v2:

- The changes must be relative to the below tree since one critial patch
for the rtc-mt6397.c the series depends on was being applied into
the tree. Otherwise, for example, if the series are applied on the top
of [1], a build error must happen due to an implicit declaration of
function 'irq_create_mapping' as kbuild test robot was reporting in [2].

tree : https://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git
branch : mfd/ib-mfd-input-rtc-4.18

- changes since v1:
* Define the power controller as a function of MT6323 MFD.
* Refine the whole series commit message and title.
* Add tag Reviewed-by and Acked-by got from v1 result.
* Reuse use the DEFINE_RES_* helpers in mfd driver.
* Remove an overdone patch rtc: mediatek: remove unnecessary parentheses.
* Use devm_rtc_allocate_device() and rtc_register_device instead of
devm_rtc_device_register.
* Have an improvement according to the license rule the SPDX notation
for C header file.
* Move a file from include/linux/rtc/mt6397.h to include/linux/mfd/mt6397/rtc.h
* Refine include/linux/mfd/mt6397/rtc.h

v1:

Hi,

The series keeps to extend the capability of BPI-R2 board with MT7623 and
the result can as well bring benefits into the other MediaTek PMICs such
as MT6397 or SoCs.

The series sent across mfd, rtc, pm, dt-binding sub-system is for hoping
to let people have a simple cross-reference to know the exact dependency
and why those patches are being split in that way between each one.

Patch 1-3: Add dt-binding to the related devices newly or already
supported.
Patch 4-5: Extend driver with the functionality of MT6323 RTC device.
Patch 6-9 and 12-13: Add a few of trivial fixups, cleanups and
improvements.
Patch 10-11: It's a preparation for Patch 14 adding a new driver.
Patch 14: Add a new driver for a power-off driver.
Patch 15-16: Update MAINTAINERS with these new files being added.
