Merge tag 'tb-mfd-regulator-rtc-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd into regulator-5.14

Immutable branch between MFD, Regulator and RTC due for the v5.14 merge window

For rk3399pro boards the tcs4526 regulator supports the vdd_gpu
regulator. The tcs4526 regulator has a chip id of <0>.
Add the compatibile tcs,tcs4526

without this patch, the dmesg output is:
  fan53555-regulator 0-0010: Chip ID 0 not supported!
  fan53555-regulator 0-0010: Failed to setup device!
  fan53555-regulator: probe of 0-0010 failed with error -22
with this patch, the dmesg output is:
  vdd_gpu: supplied by vcc5v0_sys

The regulators are described as:
- Dedicated power management IC TCS4525
- Lithium battery protection chip TCS4526

This has been tested with a Radxa Rock Pi N10.

This adds support for the MediaTek MT6359 PMIC. This is a
multifunction device with the following sub modules:

- Codec
- Interrupt
- Regulator
- RTC

It is interfaced to the host controller using SPI interface
by a proprietary hardware called PMIC wrapper or pwrap.
MT6359 MFD is a child device of the pwrap.

The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.
