[PATCH 1/2] clk: sunxi: Add support for I2C gates/resets
Samuel Holland
samuel at sholland.org
Sun Sep 12 16:47:24 CEST 2021
Currently, the I2C clocks are configured in the sunxi board code. Add
the I2C clocks to the DM clock driver so they can be enabled from the
DM I2C driver using the normal uclass methods.
