They are needed for USB to work properly if CONFIG_USB_OTG_FSM

decided that it's easier to disable the OTG FSM altogether using
these properties. This works fine for most use cases, because the
OTG FSM isn't needed for simple dual role host/gadget operation.

So far we had some supplies defined for all boards in msm8916.dtsi,
while others were duplicated into every board-specific device tree.

Now that we have msm8916-pm8916.dtsi as a common include for all
standard MSM8916 devices using PM8916, move the remaining common
supplies to msm8916-pm8916.dtsi to reduce duplication a bit.

arm64: dts: qcom: msm8916: Move PM8916-specific parts to msm8916-pm8916.dtsi

Device trees for newer SoCs avoid defining the regulator nodes directly
in the SoC device tree (here: msm8916.dtsi). The reason for this is that
theoretically it is possible to combine the SoC with a different PMIC,
or to use all the regulators in a board-specific way.

Therefore let's remove those from the SoC include (msm8916.dtsi).

In practice, pretty much all MSM8916 boards were combined with PM8916,
and use the regulators in similar ways. After looking at many different
MSM8916 boards (mostly smartphones and tablets), I haven't seen a single
device that isn't using the same regulators for components integrated
into the SoC.

If all boards end up defining all regulators and supplies in the same way
then it is useful to have an include for that, so we can avoid duplicating
it everywhere. If there is really a super special board that does it
differently it could just override some properties or avoid using the
include altogether.

This patch moves the regulator and common supply definitions to
a new include called "msm8916-pm8916.dtsi".

This is also going to be useful when introducing CPR (Core Power
Reduction) later because we can configure the CPU regulator
(pm8916_spmi_s2) for all devices in this common include.

Device trees for newer SoCs avoid replicating the entire device

they set additional properties only by referencing labels,
sorted alphabetically.

Now that we have labels for all relevant nodes, convert the MSM8916
board device trees to use the same style and remove the "soc" node
entirely.

Note: There is a large block of coresight nodes in apq8016-sbc.dtsi,
which are enabled by setting status = "okay". I kept them grouped
together (not alphabetically sorted with everything else),
since that would be just unnecessarily verbose and hard to see.

This commit only moves all existing properties to nodes that reference
the respective label. The resulting binary DTBs are exactly the same.

Amit Pundir [Fri, 11 Sep 2020 16:15:40 +0000 (21:45 +0530)]
arm64: dts: qcom: Add support for Xiaomi Poco F1 (Beryllium)

Add initial dts support for Xiaomi Poco F1 (Beryllium).

This initial support is based on upstream Dragonboard 845c
(sdm845) device. With this dts, Beryllium boots AOSP up to
ADB shell over USB-C.

Supported functionality includes UFS, USB-C (peripheral),
microSD card and Vol+/Vol-/power keys. Bluetooth should work
too but couldn't be verified from adb command line, it is
verified when enabled from UI with few WIP display patches.

Just like initial db845c support, initializing the SMMU is
clearing the mapping used for the splash screen framebuffer,
which causes the device to hang during boot and recovery
needs a hard power reset. This can be worked around using:

    fastboot oem select-display-panel none

To switch ON the display back run:

    fastboot oem select-display-panel

But this only works on Beryllium devices running bootloader
version BOOT.XF.2.0-00369-SDM845LZB-1 that shipped with
Android-9 based release. Newer bootloader version do not
support switching OFF the display panel at all.

Matthias Kaehlcke [Thu, 13 Aug 2020 18:30:33 +0000 (11:30 -0700)]
arm64: dts: qcom: sc7180: Add 'sustainable_power' for CPU thermal zones

The 'sustainable_power' attribute provides an estimate of the sustained
power that can be dissipated at the desired control temperature. One
could argue that this value is not necessarily the same for all devices
with the same SoC, which may have different form factors or thermal
designs. However there are reasons to specify a (default) value at SoC
level for SC7180: most importantly, if no value is specified at all the
power_allocator thermal governor (aka 'IPA') estimates a value, using the
minimum power of all cooling devices of the zone, which can result in
overly aggressive thermal throttling. For most devices an approximate
conservative value should be more useful than the minimum guesstimate
of power_allocator. Devices that need a different value can overwrite
it in their <device>.dts. Also the thermal zones for SC7180 have a high
level of granularity (essentially one for each function block), which
makes it more likely that the default value just works for many devices.

The values correspond to 1901 MHz for the big cores, and 1804 MHz for
the small cores. The values were determined by limiting the CPU
frequencies to different max values and launching a bunch of processes
that cause high CPU load ('while true; do true; done &' is simple and
does a good job). A frequency is deemed sustainable if the CPU
temperatures don't rise (consistently) above the second trip point
('control temperature', 95 degC in this case). Once the highest
sustainable frequency is found, the sustainable power can be calculated
by multiplying the energy consumption per core at this frequency (which
can be found in /sys/kernel/debug/energy_model/) with the number of
cores that are specified as cooling devices.

The sustainable frequencies were determined at room temperature
on a device without heat sink or other passive cooling elements.

4 years agoparisc: fix PMD pages allocation by restoring pmd_alloc_one()

parisc: fix PMD pages allocation by restoring pmd_alloc_one()

Commit 1355c31eeb7e ("asm-generic: pgalloc: provide generic pmd_alloc_one()
and pmd_free_one()") converted parisc to use generic version of
pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for
PMD.

Restore the original version of pmd_alloc_one() for parisc, just use
GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and
memset.

io_uring: sanitize double poll handling

poll driven retry.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().

Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

iomap: constify ioreadX() iomem argument (as in generic implementation)

Patch series "iomap: Constify ioreadX() iomem argument", v3.

The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.

It seems there is nothing really stopping all of them to take pointer to
const.

This patch (of 4):

The ioreadX() and ioreadX_rep() helpers have inconsistent interface.  On
some architectures void *__iomem address argument is a pointer to const,
on some not.

Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

In general, strncpy() should behave like below.

char dest[10];
char *src = "12345";

strncpy(dest, src, 10);
// dest = {'1', '2', '3', '4', '5',
           '\0','\0','\0','\0','\0'}

But, current SH strnpy() has 2 issues.
1st is it will access to out-of-memory (= src + 10).
2nd is it needs big fixup for it, and maintenance __asm__
code is difficult.

To solve these issues, this patch simply uses generic strncpy()
instead of architecture specific one.
