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. Signed-off-by: Richard Zhao <linuxzsc@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
