This looks like a generic PWM output function, not specific to backlight
in any way.
Please see patch [1] adding PWM output pin groups for Exynos5420 for
reference.

Right! I just referred to the manual again, and it actually reads TOUT_0.
So, I should be probably renaming this as "pwm0_out" like in the other patch?

Yes, please. You should also add remaining ones, while at it. Basically
same patch as [1] but for Exynos5250.

Don't we also need patches to exynos_defconfig? linux.git only has
CONFIG_S3C24XX_PWM=y but for snow I've seen github.com/linux-exynos add:
CONFIG_PWM=y
CONFIG_PWM_SAMSUNG=y
CONFIG_BACKLIGHT_PWM=y

Andreas

Right. The current exynos_defconfig lacks many other options as well.
But this should be fixed by separate patch. Feel free to send a patch to
enable what you need on your hardware.
