The speed is limited by TWL5030/GAIA; a higher speed could lead to errors on the interface. The maximum I2C speed depends on the system clock for GAIA: 2.2 MHz (sys-clk = 19.2 MHz) 2.4 MHz (sys-clk = 26 MHz) 2.9 MHz (sys-clk = 38.4 MHz) For Zoom2/Zoom3/SDP3630 the system clock is 26Mhz and hence choose 2.4Mhz for I2C1 bus speed Signed-off-by: Vikram Pandita Signed-off-by: Tony Lindgren --- Reading git-diff-tree failed
