Merge tag 'sh-pfc-for-v5.9-tag2' of git://git./linux/kernel/git/geert/renesas-drivers into devel

pinctrl: sh-pfc: Updates for v5.9 (take two)

  - Add support for the new RZ/G2H (R8A774E1) SoC,
  - One more conversion of DT bindings to json-schema,
  - Fix RZ/A1 kerneldoc.

pinctrl: rockchip: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

pinctrl: pinctrl-amd: Do not define 'struct acpi_device_id' when !CONFIG_ACPI

Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
'struct amd_gpio_acpi_match' becomes defined but unused.

of 'mtk_default_register_base_names' and there is nowhere we can place the
definition to void the need for __maybe_unused except its own headerfile,
which seems like overkill. So instead we tell the compiler that it's okay
for it to be unused by some of the consumers.

pinctrl: nsp: Set irq handler based on trig type

Rather than always using handle_simple_irq() as the gpio_irq_chip
handler, set a more appropriate handler based on the IRQ trigger type
requested. This is important for level triggered interrupts which need
to be masked during handling. Also, fix the interrupt acknowledge so
that it clears only one interrupt instead of all interrupts which are
currently active. Finally there is no need to clear the interrupt during
the interrupt handler, since the edge-triggered handler will do that for
us.

pinctrl: amd: Honor IRQ trigger type requested by the caller

This change drops the override in `amd_gpio_irq_set_type()` that
ignores the IRQ trigger type settings from the caller. The device
driver (caller) is in a better position to identify the right trigger
type for the device based on the usage as well as the information
exposed by the BIOS. There are instances where the device driver might
want to configure the trigger type differently in different modes. An
example of this is gpio-keys driver which configures IRQ type as
trigger on both edges (to identify assert and deassert events) when in
S0 and reconfigures the trigger type using the information provided by
the BIOS when going into suspend to ensure that the wake happens on
the required edge.

This override in `amd_gpio_irq_set_type()` prevents the caller from
being able to reconfigure trigger type once it is set either based on
ACPI information or the type used by the first caller for IRQ on a
given GPIO line.

Without this change, pen-insert gpio key (used by garaged stylus on a
Chromebook) works fine in S0 (i.e. insert and eject events are
correctly identified), however, BIOS configuration for wake on only
pen eject i.e. only-rising edge or only-falling edge is not honored.

With this change, it was verified that pen-insert gpio key behavior is
correct in both S0 and for wakeup from S3.

pinctrl: ingenic: Properly detect GPIO direction when configured for IRQ

The PAT1 register contains information about the IRQ type (edge/level)
for input GPIOs with IRQ enabled, and the direction for non-IRQ GPIOs.
So it makes sense to read it only if the GPIO has no interrupt
configured, otherwise input GPIOs configured for level IRQs are
misdetected as output GPIOs.

pinctrl: ingenic: Enhance support for IRQ_TYPE_EDGE_BOTH

Ingenic SoCs don't natively support registering an interrupt for both
rising and falling edges. This has to be emulated in software.

Until now, this was emulated by switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING according to the level of
the GPIO. While this worked most of the time, when used with GPIOs that
need debouncing, some events would be lost. For instance, between the
time a falling-edge interrupt happens and the interrupt handler
configures the hardware for rising-edge, the level of the pin may have
already risen, and the rising-edge event is lost.

To address that issue, instead of switching back and forth between
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING, we now switch back and
forth between IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_LEVEL_HIGH. Since we
always switch in the interrupt handler, they actually permit to detect
level changes. In the example above, if the pin level rises before
switching the IRQ type from IRQ_TYPE_LEVEL_LOW to IRQ_TYPE_LEVEL_HIGH,
a new interrupt will raise as soon as the handler exits, and the
rising-edge event will be properly detected.

pinctrl: meson: fix drive strength register and bit calculation

If a GPIO bank has greater than 16 pins, PAD_DS_REG is split into two
or more registers. However, when register and bit were calculated, the
first register defined in the bank was used, and the bit was calculated
based on the first pin. This causes problems in setting the driving
strength.

The following method was used to solve this problem:
A bit is calculated first using predefined strides. Then, If the bit is
32 or more, the register is changed by the quotient of the bit divided
by 32. And the bit is set to the remainder.

pinctrl-single: fix pcs_parse_pinconf() return value

This patch causes pcs_parse_pinconf() to return -ENOTSUPP when no
pinctrl_map is added.  The current behavior is to return 0 when
!PCS_HAS_PINCONF or !nconfs.  Thus pcs_parse_one_pinctrl_entry()
incorrectly assumes that a map was added and sets num_maps = 2.

Analysis:
=========
The function pcs_parse_one_pinctrl_entry() calls pcs_parse_pinconf()
if PCS_HAS_PINCONF is enabled.  The function pcs_parse_pinconf()
returns 0 to indicate there was no error and num_maps is then set to 2:

980 static int pcs_parse_one_pinctrl_entry(struct pcs_device *pcs,
981                                                 struct device_node *np,
982                                                 struct pinctrl_map **map,
983                                                 unsigned *num_maps,
984                                                 const char **pgnames)
985 {
<snip>
1053         (*map)->type = PIN_MAP_TYPE_MUX_GROUP;
1054         (*map)->data.mux.group = np->name;
1055         (*map)->data.mux.function = np->name;
1056
1057         if (PCS_HAS_PINCONF && function) {
1058                 res = pcs_parse_pinconf(pcs, np, function, map);
1059                 if (res)
1060                         goto free_pingroups;
1061                 *num_maps = 2;
1062         } else {
1063                 *num_maps = 1;
1064         }

However, pcs_parse_pinconf() will also return 0 if !PCS_HAS_PINCONF or
!nconfs.  I believe these conditions should indicate that no map was
added by returning -ENOTSUPP. Otherwise pcs_parse_one_pinctrl_entry()
will set num_maps = 2 even though no maps were successfully added, as
it does not reach "m++" on line 940:

895 static int pcs_parse_pinconf(struct pcs_device *pcs, struct device_node *np,
896                              struct pcs_function *func,
897                              struct pinctrl_map **map)
898
899 {
900         struct pinctrl_map *m = *map;
<snip>
917         /* If pinconf isn't supported, don't parse properties in below. */
918         if (!PCS_HAS_PINCONF)
919                 return 0;
920
921         /* cacluate how much properties are supported in current node */
922         for (i = 0; i < ARRAY_SIZE(prop2); i++) {
923                 if (of_find_property(np, prop2[i].name, NULL))
924                         nconfs++;
925         }
926         for (i = 0; i < ARRAY_SIZE(prop4); i++) {
927                 if (of_find_property(np, prop4[i].name, NULL))
928                         nconfs++;
929         }
930         if (!nconfs)
919                 return 0;
932
933         func->conf = devm_kcalloc(pcs->dev,
934                                   nconfs, sizeof(struct pcs_conf_vals),
935                                   GFP_KERNEL);
936         if (!func->conf)
937                 return -ENOMEM;
938         func->nconfs = nconfs;
939         conf = &(func->conf[0]);
940         m++;

This situtation will cause a boot failure [0] on the BeagleBone Black
(AM3358) when am33xx_pinmux node in arch/arm/boot/dts/am33xx-l4.dtsi
has compatible = "pinconf-single" instead of "pinctrl-single".

The patch fixes this issue by returning -ENOSUPP when !PCS_HAS_PINCONF
or !nconfs, so that pcs_parse_one_pinctrl_entry() will know that no
map was added.

Logic is also added to pcs_parse_one_pinctrl_entry() to distinguish
between -ENOSUPP and other errors.  In the case of -ENOSUPP, num_maps
is set to 1 as it is valid for pinconf to be enabled and a given pin
group to not any pinconf properties.

Revert "btrfs: switch to iomap_dio_rw() for dio"

This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.

The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.

Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.

There have been discussions how to fix that, but revert seems to be the
least intrusive option.

net: ethernet: ti: ale: fix allmulti for nu type ale

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.

This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").

Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

"The x86 entry, exception and interrupt code rework

  This all started about 6 month ago with the attempt to move the Posix
  CPU timer heavy lifting out of the timer interrupt code and just have
  lockless quick checks in that code path. Trivial 5 patches.

  This unearthed an inconsistency in the KVM handling of task work and
  the review requested to move all of this into generic code so other
  architectures can share.

  Valid request and solved with another 25 patches but those unearthed
  inconsistencies vs. RCU and instrumentation.

  Digging into this made it obvious that there are quite some
  inconsistencies vs. instrumentation in general. The int3 text poke
  handling in particular was completely unprotected and with the batched
  update of trace events even more likely to expose to endless int3
  recursion.

  In parallel the RCU implications of instrumenting fragile entry code
  came up in several discussions.

  The conclusion of the x86 maintainer team was to go all the way and
  make the protection against any form of instrumentation of fragile and
  dangerous code pathes enforcable and verifiable by tooling.

  A first batch of preparatory work hit mainline with commit
  d5f744f9a2ac ("Pull x86 entry code updates from Thomas Gleixner")

  That (almost) full solution introduced a new code section
  '.noinstr.text' into which all code which needs to be protected from
  instrumentation of all sorts goes into. Any call into instrumentable
  code out of this section has to be annotated. objtool has support to
  validate this.

  Kprobes now excludes this section fully which also prevents BPF from
  fiddling with it and all 'noinstr' annotated functions also keep
  ftrace off. The section, kprobes and objtool changes are already
  merged.

  The major changes coming with this are:

    - Preparatory cleanups

    - Annotating of relevant functions to move them into the
      noinstr.text section or enforcing inlining by marking them
      __always_inline so the compiler cannot misplace or instrument
      them.

    - Splitting and simplifying the idtentry macro maze so that it is
      now clearly separated into simple exception entries and the more
      interesting ones which use interrupt stacks and have the paranoid
      handling vs. CR3 and GS.

    - Move quite some of the low level ASM functionality into C code:

       - enter_from and exit to user space handling. The ASM code now
         calls into C after doing the really necessary ASM handling and
         the return path goes back out without bells and whistels in
         ASM.

       - exception entry/exit got the equivivalent treatment

       - move all IRQ tracepoints from ASM to C so they can be placed as
         appropriate which is especially important for the int3
         recursion issue.

    - Consolidate the declaration and definition of entry points between
      32 and 64 bit. They share a common header and macros now.

    - Remove the extra device interrupt entry maze and just use the
      regular exception entry code.

    - All ASM entry points except NMI are now generated from the shared
      header file and the corresponding macros in the 32 and 64 bit
      entry ASM.

    - The C code entry points are consolidated as well with the help of
      DEFINE_IDTENTRY*() macros. This allows to ensure at one central
      point that all corresponding entry points share the same
      semantics. The actual function body for most entry points is in an
      instrumentable and sane state.

      There are special macros for the more sensitive entry points, e.g.
      INT3 and of course the nasty paranoid #NMI, #MCE, #DB and #DF.
      They allow to put the whole entry instrumentation and RCU handling
      into safe places instead of the previous pray that it is correct
      approach.

    - The INT3 text poke handling is now completely isolated and the
      recursion issue banned. Aside of the entry rework this required
      other isolation work, e.g. the ability to force inline bsearch.

    - Prevent #DB on fragile entry code, entry relevant memory and
      disable it on NMI, #MC entry, which allowed to get rid of the
      nested #DB IST stack shifting hackery.

    - A few other cleanups and enhancements which have been made
      possible through this and already merged changes, e.g.
      consolidating and further restricting the IDT code so the IDT
      table becomes RO after init which removes yet another popular
      attack vector

    - About 680 lines of ASM maze are gone.

  There are a few open issues:

   - An escape out of the noinstr section in the MCE handler which needs
     some more thought but under the aspect that MCE is a complete
     trainwreck by design and the propability to survive it is low, this
     was not high on the priority list.

   - Paravirtualization

     When PV is enabled then objtool complains about a bunch of indirect
     calls out of the noinstr section. There are a few straight forward
     ways to fix this, but the other issues vs. general correctness were
     more pressing than parawitz.

   - KVM

     KVM is inconsistent as well. Patches have been posted, but they

   - IDLE

     Pretty much the same problems can be found in the low level idle
     code especially the parts where RCU stopped watching. This was
     beyond the scope of the more obvious and exposable problems and is
     on the todo list.

  The lesson learned from this brain melting exercise to morph the
  evolved code base into something which can be validated and understood
  is that once again the violation of the most important engineering
  principle "correctness first" has caused quite a few people to spend
  valuable time on problems which could have been avoided in the first
  place. The "features first" tinkering mindset really has to stop.

  With that I want to say thanks to everyone involved in contributing to
  this effort. Special thanks go to the following people (alphabetical
  order): Alexandre Chartre, Andy Lutomirski, Borislav Petkov, Brian
  Gerst, Frederic Weisbecker, Josh Poimboeuf, Juergen Gross, Lai
  Jiangshan, Macro Elver, Paolo Bonzin,i Paul McKenney, Peter Zijlstra,
  Vitaly Kuznetsov, and Will Deacon"
