  - Add Multiplatform support
  - Add Reference DT

* r8a7791 (R-Car M2) based Koelsch board
  - Add pinctrl_register_mappings() for Koelsch
  - Hook up SW30-SW36 on Koelsch
  - Mark GPIO keys as wake-up sources
  - Use ->init_late()
  - Add Multiplatform support
  - Set .debounce_interval for GPIO keys
  - Add SW2 to GPIO keys
  - Add Led 6, 7 and 8 support
  - Add reference DT
  - Enable PFC/GPIO

* r8a7790 (R-Car H2) based Lager board
  - Add gpio/fixed regulator for SDHI
  - Add SPI FLASH support on QSPI
  - Mark GPIO keys as wake-up sources
  - Use ->init_late()
  - Set .debounce_interval for GPIO keys

* r8a7778 (R-Car M1) based Bock-W board

Allows the configuration of the timer frequency. It is customary
to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
case of low timer frequencies other values may be more suitable.
SH-Mobile systems using a 32768 Hz RCLK for clock events may want
to select a HZ value such as 128 that can evenly divide RCLK.

want to select a HZ value such as 128 that can evenly divide RCLK.
A HZ value that does not divide evenly may cause timer drift.
