Since the second min() argument can be less than 0 a signed
variable is required for assignment. However, the non-sized
type size_t is passed in from the userspace handlers. In order
to firstly compare, then assign the smallest value, we firstly
need to cast them both to the same as the receiving size_t typed
variable.

It appears as though the driver data property 'resource_size_t *base'
was being used to store 2 different types of addresses (physical and
IO-mapped) under a single declared type.
Fortunately, no value is recalled from the driver data entry, so it
can be easily omitted. Instead we can use the value obtained directly
from the platform resource to pass through Regmap into the call-backs
to be used for the SMCC call and use a local dedicated __iomem
variable for IO-remapping.

This Microcontroller is present on the Khadas VIM1, VIM2, VIM3 and Edge
boards.
It has multiple boot control features like password check, power-on
options, power-off control and system FAN control on recent boards.
This implements a very basic MFD driver with the fan control and User
NVMEM cells.

Whilst it doesn't matter if the internal 32k clock register settings
are cleaned up on exit, as the part will be turned off losing any
settings, hence the driver hasn't historially bothered. The external
clock should however be cleaned up, as it could cause clocks to be
left on, and will at best generate a warning on unbind.
Add clean up on both the probe error path and unbind for the 32k
clock.

BUG_ON macros are generally frowned upon when the issue isn't super
critical, the kernel can certainly carry on with the 32k clock on the
CODEC in a bad state so change the BUG_ON to a WARN_ON.

Implement clock event driver using low power STM32 timers.
Low power timer counters running even when CPUs are stopped.
It could be used as clock event broadcaster to wake up CPUs but not like
a clocksource because each it rise an interrupt the counter restart from 0.
Low power timers have a 16 bits counter and a prescaler which allow to
divide the clock per power of 2 to up 128 to target a 32KHz rate.

SafeSetID is capable of making allow/deny decisions for set*uid calls
on a system, and we want to add similar functionality for set*gid
calls. The work to do that is not yet complete, so probably won't make
it in for v5.8, but we are looking to get this simple patch in for
v5.8 since we have it ready. We are planning on the rest of the work
for extending the SafeSetID LSM being merged during the v5.9 merge
window.
This patch was sent to the security mailing list and there were no objections.

security: Add LSM hooks to set*gid syscalls
The SafeSetID LSM uses the security_task_fix_setuid hook to filter
set*uid() syscalls according to its configured security policy. In
preparation for adding analagous support in the LSM for set*gid()
syscalls, we add the requisite hook here. Tested by putting print
statements in the security_task_fix_setgid hook and seeing them get hit
during kernel boot.
