The Synopsys I2C Controller has a bus clock that some SoCs require to access the registers. This series also details the new clock property in the bindings documentation.
v3: - busclk renamed to pclk. - Added comment with dw_i2c_dev struct definition describing pclk. - Added enable rollback of first clock if second fails to enable. - Changed clocks and clock-names sections to use term "peripheral clock" (pclk) instead of "bus clock" (busclk) in dt-bindings documentation. v2: - Use new devm_clk_get_optional() function as it simplifies handling when the optional clock is not present.
