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.
Best regards,
Tomasz
