Subject[PATCH v4 0/2] i2c: designware: Add support for a bus clock
Date
The Synopsys I2C Controller has a peripheral clock that some SoCs 
require to access the registers. 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.
