In order to:
1. prevent BCLK from turning on by other component.
2. keep BCLK and LRCLK being present at the same time

- 2 SDMMC slots.
- A Realtek rtl8821cs WiFi/Bluetooth adapter.
- A mini HDMI port.
- A USB C host port and a USB C otg port (currently only working as

- Multiple GPIO buttons and a single ADC button.

- A headphone jack with amplified stereo speakers via a SGM4865 amp.
- A PWM based vibrator for force feedback.
The RG353P has:
- 2GB LPDDR4 RAM.
- A 32GB eMMC.
- A 3.5 inch 640x480 4-lane DSI panel of unknown origin with an i2c
controlled touchscreen (touchscreen is a Hynitron CST340).
The RG503 has:
- 1GB LPDDR4 RAM.
- A 5 inch 960x544 AMOLED 2-lane DSI/DBI panel manufactured by Samsung
with part number ams495qa04. Data for this panel is provided via the
DSI interface, however commands are sent via a 9-bit 3-wire SPI
interface. The MISO pin of SPI3 of the SOC is wired to the input of
the panel, so it must be bitbanged.
This devicetree enables the following hardware:
- HDMI (plus audio).
- Analog audio, including speakers.
- All buttons.
- All SDMMC/eMMC/SDIO controllers.
- The ADC joysticks (note a pending patch is required to use them).
- WiFi/Bluetooth (note out of tree drivers are required).
- The PWM based vibrator motor.
The following hardware is not enabled:
- The display panels (drivers are being written and there are issues
with the upstream DSI and VOP2 subsystems).
- Battery (driver pending).
- Touchscreen on the RG353P (note the i2c2 bus is enabled for it).

tracing/eprobes: Have event probes be consistent with kprobes and uprobes
Currently, if a symbol "@" is attempted to be used with an event probe
(eprobes), it will cause a NULL pointer dereference crash.
Both kprobes and uprobes can reference data other than the main registers.
Such as immediate address, symbols and the current task name. Have eprobes
do the same thing.
For "comm", if "comm" is used and the event being attached to does not
have the "comm" field, then make it the "$comm" that kprobes has. This is
consistent to the way histograms and filters work.

relational/dynamic etc.

The variable $comm is hard coded as a string, which is true for both

most cases the "comm" field would be a string, but there's no guarantee of
that fact.
Do not assume that comm is a string. Not to mention, it currently forces
comm fields to fault, as string processing for event probes is currently
broken.

tracing/perf: Fix double put of trace event when init fails
If in perf_trace_event_init(), the perf_trace_event_open() fails, then it
will call perf_trace_event_unreg() which will not only unregister the perf
trace event, but will also call the put() function of the tp_event.
The problem here is that the trace_event_try_get_ref() is called by the
caller of perf_trace_event_init() and if perf_trace_event_init() returns a
failure, it will then call trace_event_put(). But since the
perf_trace_event_unreg() already called the trace_event_put() function, it
triggers a WARN_ON().
WARNING: CPU: 1 PID: 30309 at kernel/trace/trace_dynevent.c:46 trace_event_dyn_put_ref+0x15/0x20
If perf_trace_event_reg() does not call the trace_event_try_get_ref() then
the perf_trace_event_unreg() should not be calling trace_event_put(). This
breaks symmetry and causes bugs like these.
Pull out the trace_event_put() from perf_trace_event_unreg() and call it
in the locations that perf_trace_event_unreg() is called. This not only
fixes this bug, but also brings back the proper symmetry of the reg/unreg
vs get/put logic.

tracing: React to error return from traceprobe_parse_event_name()
The function traceprobe_parse_event_name() may set the first two function

unsuccessful completion of the function. Hence, it is not sufficient to
just check the result of the two function arguments for being not null,

Prior to that commit, the modules order was determined based on
vmlinux-dirs, which lists core-y/m, drivers-y/m, libs-y/m, in this order.
Now, subdir-modorder lists them in a different order: core-y/m, libs-y/m,
drivers-y/m.
Presumably, there was no practical issue because the modules in drivers
and libs are orthogonal, but there is no reason to have this distortion.
Get back to the original order.

modpost: fix module versioning when a symbol lacks valid CRC
Since commit
7b4537199a4a ("kbuild: link symbol CRCs at final link,
removing CONFIG_MODULE_REL_CRCS"), module versioning is broken on
some architectures. Loading a module fails with "disagrees about
version of symbol module_layout".
On such architectures (e.g. ARCH=sparc build with sparc64_defconfig),
modpost shows a warning, like follows:
WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
Is "_mcount" prototyped in <asm/asm-prototypes.h>?
Previously, it was a harmless warning (CRC check was just skipped),
but now wrong CRCs are used for comparison because invalid CRCs are
just skipped.

Please notice __crc__mcount is missing here.
When the module subsystem looks up a CRC that comes after, it results
in reading out a wrong address. For example, when __crc__printk is
needed, the module subsystem reads 0xc53b44 instead of 0xc53b40.
All CRC entries must be output for correct index accessing. Invalid
CRCs will be unused, but are needed to keep the one-to-one mapping
between __ksymtab_* and __crc_*.
The best is to fix all modpost warnings, but several warnings are still
remaining on less popular architectures.

ata: libata: Set __ATA_BASE_SHT max_sectors
Commit
0568e6122574 ("ata: libata-scsi: cap ata_device->max_sectors
according to shost->max_sectors") inadvertently capped the max_sectors
value for some SATA disks to a value which is lower than we would want.
For a device which supports LBA48, we would previously have request queue
max_sectors_kb and max_hw_sectors_kb values of 1280 and 32767 respectively.
For AHCI controllers, the value chosen for shost max sectors comes from
the minimum of the SCSI host default max sectors in
SCSI_DEFAULT_MAX_SECTORS (1024) and the shost DMA device mapping limit.
This means that we would now set the max_sectors_kb and max_hw_sectors_kb
values for a disk which supports LBA48 at 512, ignoring DMA mapping limit.
As report by Oliver at [0], this caused a performance regression.
Fix by picking a large enough max sectors value for ATA host controllers
such that we don't needlessly reduce max_sectors_kb for LBA48 disks.

perf tools: Support reading PERF_FORMAT_LOST
The recent kernel added lost count can be read from either read(2) or
ring buffer data with PERF_SAMPLE_READ. As it's a variable length data
we need to access it according to the format info.
But for perf tools use cases, PERF_FORMAT_ID is always set. So we can
only check PERF_FORMAT_LOST bit to determine the data format.
Add sample_read_value_size() and next_sample_read_value() helpers to
make it a bit easier to access. Use them in all places where it reads
the struct sample_read_value.

libperf: Handle read format in perf_evsel__read()
The perf_counts_values should be increased to read the new lost data.
Also adjust values after read according the read format.
This supports PERF_FORMAT_GROUP which has a different data format but
it's only available for leader events. Currently it doesn't have an API
to read sibling (member) events in the group. But users may read the
sibling event directly.
Also reading from mmap would be disabled when the read format has ID or

perf cpumap: Fix alignment for masks in event encoding
A mask encoding of a cpu map is laid out as:
u16 nr
u16 long_size
unsigned long mask[];
However, the mask may be 8-byte aligned meaning there is a 4-byte pad
after long_size. This means 32-bit and 64-bit builds see the mask as
being at different offsets. On top of this the structure is in the byte
data[] encoded as:
u16 type
char data[]
This means the mask's struct isn't the required 4 or 8 byte aligned, but
is offset by 2. Consequently the long reads and writes are causing
undefined behavior as the alignment is broken.
Fix the mask struct by creating explicit 32 and 64-bit variants, use a
union to avoid data[] and casts; the struct must be packed so the
layout matches the existing perf.data layout. Taking an address of a
member of a packed struct breaks alignment so pass the packed
perf_record_cpu_map_data to functions, so they can access variables with
the right alignment.
As the 64-bit version has 4 bytes of padding, optimizing writing to only
write the 32-bit version.
Committer notes:
Disable warnings about 'packed' that break the build in some arches like
riscv64, but just around that specific struct.
