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. Feng-Yi Hsueh (2): dt-bindings: input: Add Nuvoton MA35D1 keypad controller Input: keyboard: Add Nuvoton MA35D1 keypad driver --- 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. .../bindings/input/nuvoton,ma35d1-keypad.yaml | 75 ++++ drivers/input/keyboard/Kconfig | 11 + drivers/input/keyboard/Makefile | 1 + drivers/input/keyboard/ma35d1_keypad.c | 407 ++++++++++++++++++ 4 files changed, 494 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/nuvoton,ma35d1-keypad.yaml create mode 100644 drivers/input/keyboard/ma35d1_keypad.c -- 2.43.0
