[PATCH v4 0/4] ARM: s3c: crag6410: Convert to software nodes and properties

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

Hi,

This series converts the Cragganmore 6410 board to generic software nodes
and device properties, allowing the removal of legacy GPIO lookup tables.

We add software node propagation support to the wm831x MFD core to route
DVS GPIOs to the PMIC regulator, and convert the peripherals on the
Cragganmore board (PMIC DVS GPIO, basic-mmio-gpio, LEDs, WM1250, and SPI0)
from legacy GPIO lookup tables to software nodes and properties. This
eliminates the legacy GPIO lookup tables on the board and fixes incorrect
GPIO chip names from previous conversions.

Hopefully Krzysztof can finish merging the series through the soc tree
once Lee acks the MFD part.

Thanks!

Changes in v4:
- Patches 1-6 from v3 were applied to the samsung-soc tree
- Rebased onto latest linux-next
- Capitalized the MFD patch subject per MFD subsystem conventions
- Added Lee Jones and the MFD mailing list to recipients
- Link to v3: https://patch.msgid.link/20260711-samsung-kp-v3-0-b2fcaba77aff@gmail.com

Changes in v3:
- Fixed legacy property handling regression in the keypad driver by
  separating compact and verbose binding paths
- Removed redundant registration of crag6410_mmgpio_node from
  mach-crag6410.c
- Removed dead S3C64XX_SETUP_KEYPAD Kconfig symbol definition and
  selection
- Fixed missing newline in pr_err() message in mach-crag6410.c
- Redesigned PMIC DVS support to keep regulator driver changes minimal
  (untouched) and only use software nodes for GPIO routing via MFD core
- Link to v2: https://patch.msgid.link/20260708-samsung-kp-v2-0-3c6ed4c9b3b6@gmail.com

Changes in v2:
- Patches 1-8 of v1 were merged into mainline, dropping them from this
  series
- Rebased patches 9-14 of v1 onto latest next
- Resolved conflicts in mach-crag6410.c
- Removed redundant "out of memory" error messages from the keypad
  driver
- Added an infrastructure patch to register and attach software nodes
  for Samsung gpio_chips
- Converted basic-mmio-gpio and LEDs on Cragganmore 6410 to software
  properties in a new separate patch
- Addressed DT bindings feedback on the compact binding patch
- Fixed proximity switch event type for GPIO keys
- Added support for software nodes in wm831x regulator driver
- Converted PMIC DVS on Cragganmore 6410 to software properties using
  the new driver support
- Removed legacy DVS platform data fields and cleaned up driver
  fallback.
