I was just doing some build tests on the series and noticed that it
fails with this:

	  CC [M]  drivers/pwm/pwm-imx.o
	/home/thierry.reding/src/kernel/linux-pwm.git/drivers/pwm/pwm-imx.c: In function 'imx_pwm_config_v2':
	/home/thierry.reding/src/kernel/linux-pwm.git/drivers/pwm/pwm-imx.c:140:2: error: implicit declaration of function 'cpu_is_mx25' [-Werror=implicit-function-declaration]

This breaks bisection in the middle of the series. It seems to be
related to this change.

This probably needs to be postponed to the next patch, until the final
reference to cpu_is_mx25() is removed.
