The Pyra-Handheld originally used the tca6424 but recently we have
replaced it by the pin and package compatible pcal6524. So let's
add this to the bindings and the driver.
And while we are at it, the pcal9555a does not have a compatible entry
either but is already supported by the device id table.

With this patch both clock have now a name, but in order to be backward

use this clock with a device tree using the old binding.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma fixes from Doug Ledford:
- Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging
from bugs under load to bad error case handling
- There in one largish patch fixing the locking in bnxt_re to avoid a
machine hard lock situation
- A few core bugs on error paths
- A patch to reduce stack usage in the new CQ API
- One mlx5 regression introduced in this merge window
- There were new syzkaller scripts written for the RDMA subsystem and
we are fixing issues found by the bot
- One of the commits (aa0de36a40 “RDMA/mlx5: Fix integer overflow
while resizing CQ”) is missing part of the commit log message and one
of the SOB lines. The original patch was from Leon Romanovsky, and a
cut-n-paste separator in the commit message confused patchworks which
then put the end of message separator in the wrong place in the
downloaded patch, and I didn’t notice in time. The patch made it into
the official branch, and the only way to fix it in-place was to
rebase. Given the pain that a rebase causes, and the fact that the
patch has relevant tags for stable and syzkaller, a revert of the
munged patch and a reapplication of the original patch with the log
message intact was done.

Correct a module loading race condition between the DELL_SMBIOS backend
modules and the first user by converting them to bool features of the
DELL_SMBIOS driver. Fixup the resulting Kconfig dependency issue with
DCDBAS.
The following is an automated git shortlog grouped by driver:
- Resolve dependency error on DCDBAS
- Allow for SMBIOS backend defaults
- Link all dell-smbios-* modules together
- Rename dell-smbios source to dell-smbios-base
- Correct some style warnings
