Hi All,

Here are 2 patches which together fix the LCD panel staying black
(backlight brightness 0) after a suspend / resume on some Bay Trail
devices. I guess these devices are unique in that their firmware
disables the LPSS PWM APB clock / reset bits on a suspend / resume.

The first patch is necessary to fix the second patch potentially
causing a regression on some devices. So I suggest that we merge both
patches through the pwm tree, with an ack from Rafael for the ACPI
bits. Rafael, can we have your ack for that please?

Regards,

Hans
