[U-Boot] [PATCH 00/50] rockchip: Add support for cros_ec keyboard

[Simon Glass]

This series provides a number of new features and improvements leading to
enabling the keyboard (via Chrome OS EC) on jerry. This is conneected via
SPI and uses its own message protocol.

Features and fixes are needed in the rockchip code to make this work include:
    - RK808 PMIC and regulator driver
    - Fixes and improvements to the i2c and SPI drivers
    - A full implementation of the GPIO driver
    - Additional clock support
    - Additional pinctrl support

The series moves a few rockchip boards to use the full pinctrl driver. I'm
not sure this is a great idea, as it slows down start-up noticeably. It is
currently needed for the display series (to come), but I intend to change
that.

  dm: power: Tidy up debugging output and return values
  dm: power: Allow regulators to not implement all operations
  dm: clk: Add a simple version of clk_get_by_index()
  rockchip: sdram: Use the rk_clr/setreg() interface
  rockchip: reset: Use the rk_clr/setreg() interface
  rockchip: spi: Remember the last speed to avoid re-setting it
  rockchip: spi: Correct the bus init code
  rockchip: clk: Make rkclk_get_clk() SoC-specific
