[PATCH v2 0/2] Add Nuvoton MA35D1 keypad controller support

[Feng-Yi Hsueh <fyhsueh4linux@gmail.com>]

The Nuvoton MA35D1 SoC provides a hardware matrix keypad
controller supporting up to eight rows and eight columns.

This series adds the Device Tree binding and input driver
for key press/release events, clock management, and system
suspend/resume support.

Tested on a Nuvoton MA35D1 board with a 4x1 keypad
configuration and a 1 MHz KPI clock using evtest.

Changes since v1:
  - dt-bindings: add optional resets and reference input.yaml.
  - dt-bindings: fix interrupt, clock, and keymap formatting.
  - input: use guard(mutex) in suspend/resume callbacks.
  - input: rename error variables from ret to error and
    explicitly return 0 on successful resume.
  - input: remove the unnecessary linux/mod_devicetable.h include.
