Subject: [PATCH v5 0/2] i2c: designware: Add support for a bus clock
Date: Thu, 28 Feb 2019 13:52:08 +0000 [thread overview]
Message-ID: <1551361930-24434-1-git-send-email-gareth.williams.jx@renesas.com> (raw)
The Synopsys I2C Controller has an interface clock that some SoCs
require to access the registers. This series also details the new clock
property in the bindings documentation.
v5:
- Code comments and commit messages updated to reference "interface clock"
instead of "peripheral clock".
v4:
- Code comments and commit messages updated to reference "peripheral
clock"
instead of "bus clock".
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.
