On some platforms (i.MX 7) the peripheral clock is required during register access. Make sure that the clock is kept enabled when accessing registers. Signed-off-by: Stefan Agner <stefan@agner.ch> --- Hi Thierry, hi Lukasz, This patch applies ontop of Lukasz "pwm: imx: Provide atomic operation for IMX PWM driver" patchset. With that, my expressed concern to patch 2 is solved. -- Stefan drivers/pwm/pwm-imx.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
