I think that comment is incorrect. If tcmp is written as -1UL then the
LED totally turns off. And there is nothing in the Exynos4412 manual
to suggest that -1UL should be set in the TCMP

This is strange. I remember verifying various edge cases with a scope on
an Exynos4210-based Origen board and I don't recall any issues.
Unfortunately I don't have appropriate hardware to recheck this specific
case
Hi,
I'm using pwm-samsung on Exynos4412 for a variable-brightness LED.
When the LED is set to maximum brightness via the pwm-leds driver, we
arrive at pwm_samsung_config with duty_ns = period_ns, i.e. 100% duty
cycle.
This function does:
/* -1UL will give 100% duty. */
--tcmp;
