Richard Zhao	43309f3b52	i2c: imx: check busy bit when START/STOP ... The controller can't do anything else before it actually generates START/STOP. So we check busy bit to make sure START/STOP is successfully finished. If we don't check busy bit, START/STOP may fail on some fast CPUs.

Wolfram Sang	65de394df2	i2c: imx: Make disable_delay a per-device variable ... 'disable_delay' was static which is wrong as it is calculated using the per-device bus speed. This patch turns 'disable_delay' into a per-device variable.
