As seen on any other pinctrl subdriver that calls code from a main driver,
each subdriver needs to have a different compatible string. We don't want
the same compatible string to match a different subdriver's pinmux data as
it's not for our SoC.
Therefore, add new compatible strings for each pinctrl subdriver. Change
driver name on all subdrivers accordingly.

pinctrl: renesas: Updates for v5.19
- Add support for the new RZ/G2UL SoC,
- Add drive-strength support for R-Car E3,
- Add RPC/QSPI pin groups on R-Car E3 and E3,
- Miscellaneous fixes and improvements.
Test case 71 'Convert perf time to TSC' is not supported on s390.
Subtest 71.1 is skipped with the correct message, but subtest 71.2 is
not skipped and fails.
The root cause is function evlist__open() called from
test__perf_time_to_tsc(). evlist__open() returns -ENOENT because the
event cycles:u is not supported by the selected PMU, for example
platform s390 on z/VM or an x86_64 virtual machine.
The PMU driver returns -ENOENT in this case. This error is leads to the
failure.
Fix this by returning TEST_SKIP on -ENOENT.
Output before:
71: Convert perf time to TSC:
71.1: TSC support: Skip (This architecture does not support)
71.2: Perf time to TSC: FAILED!
Output after:
71: Convert perf time to TSC:
71.1: TSC support: Skip (This architecture does not support)
71.2: Perf time to TSC: Skip (perf_read_tsc_conversion is not supported)
This also happens on an x86_64 virtual machine:
# uname -m

$ ./perf test -F 71
71: Convert perf time to TSC :
71.1: TSC support : Ok
71.2: Perf time to TSC : FAILED!

Continues to work on x86_64:

Since commit bb30acae4c ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't report result if the PERF_SAMPLE_DATA_SRC bit is missed in sample
type.
The commit ffab487052 ("perf: arm-spe: Fix perf report
--mem-mode") partially fixes the issue. It adds PERF_SAMPLE_DATA_SRC
bit for Arm SPE event, this allows the perf data file generated by
kernel v5.18-rc1 or later version can be reported properly.
On the other hand, perf tool still fails to be backward compatibility
for a data file recorded by an older version's perf which contains Arm
SPE trace data. This patch is a workaround in reporting phase, when
detects ARM SPE PMU event and without PERF_SAMPLE_DATA_SRC bit, it will
force to set the bit in the sample type and give a warning info.

Some of the pinmuxing bits described in rk3308_mux_recalced_data are wrong,
pointing to non-existing registers.
Fix the entire table.
Also add a comment in front of each entry with the same string that appears
in the datasheet to make the table easier to compare with the docs.
This fix has been tested on real hardware for the gpio3b3_sel entry.

Samsung pinctrl drivers fixes for v5.18
1. Fix sparse warning introduced in v5.18-rc1.
2. Fix possible unmet Kconfig dependency with COMPILE_TEST, present
since v4.3 or earlier.
By being a bit smarter about how the SoC version checks are performed,
it is possible to have all the code paths that correspond to SoCs
disabled in the kernel config automatically marked as dead code by the
compiler, and therefore garbage-collected.
With this patch, when compiling a kernel that only targets the JZ4760
for instance, the driver is now about 4.5 KiB smaller.

Pull mount_setattr fix from Christian Brauner:
"The recent cleanup in e257039f0f ("mount_setattr(): clean the
control flow and calling conventions") switched the mount attribute
codepaths from do-while to for loops as they are more idiomatic when
walking mounts.
However, we did originally choose do-while constructs because if we
request a mount or mount tree to be made read-only we need to hold
writers in the following way: The mount attribute code will grab
lock_mount_hash() and then call mnt_hold_writers() which will
_unconditionally_ set MNT_WRITE_HOLD on the mount.
Any callers that need write access have to call mnt_want_write(). They
will immediately see that MNT_WRITE_HOLD is set on the mount and the
caller will then either spin (on non-preempt-rt) or wait on
lock_mount_hash() (on preempt-rt).
The fact that MNT_WRITE_HOLD is set unconditionally means that once
mnt_hold_writers() returns we need to _always_ pair it with
mnt_unhold_writers() in both the failure and success paths.
The do-while constructs did take care of this. But Al's change to a
for loop in the failure path stops on the first mount we failed to
change mount attributes _without_ going into the loop to call
mnt_unhold_writers().
This in turn means that once we failed to make a mount read-only via
mount_setattr() - i.e. there are already writers on that mount - we
will block any writers indefinitely. Fix this by ensuring that the for
loop always unsets MNT_WRITE_HOLD including the first mount we failed
to change to read-only. Also sprinkle a few comments into the cleanup
code to remind people about what is happening including myself. After
all, I didn't catch it during review.
This is only relevant on mainline and was reported by syzbot. Details
about the syzbot reports are all in the commit message"
