Add dt-bindings\n2. In i2c-ls2x driver, the definition of pclk and div variables is placed on\none line\n3. list the different value of clock-input and clock-div on different platforms\n\nThanks.\n\nwanghongliang (2):\n dt-bindings: i2c: ls2x-i2c: Add clock- related properties\n i2c: ls2x: Add clock-input and clock-div properties parsing\n\n .../devicetree/bindings/i2c/loongson,ls2x-i2c.yaml | 13 +++++++++++++\n drivers/i2c/busses/i2c-ls2x.c | 7 ++++++-\n 2 files changed, 19 insertions(+), 1 deletion(-)" }
