[PATCH] i2c: mediatek: Get device clock-stretch time via dts

From: Qii Wang tSU,STA/tHD,STA/tSU,STOP maybe out of spec due to device clock-stretching or circuit loss, we could get device clock-stretch time from dts to adjust these parameters to meet the spec via EXT_CONF register. Signed-off-by: Qii Wang --- drivers/i2c/busses/i2c-mt65xx.c | 6 +- 1
