This series also details the new clock property in the bindings documentation. v4: - Code comments and commit messages updated to reference "peripheral clock" instead of "bus clock". - Rebased onto next-20190221. 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.
