Subject: Re: [PATCH v2 08/11] leds: rgb: ktd202x: Add hardware pattern support

> The KTD202x and the ET6326 can ramp the LED current up and down on
> their own: the flash timer that already does blink_set also has rise
> and fall times of up to 1.92 s. Without them, a breathing light needs
> the software pattern trigger, which is an I2C write every 50 ms.
>
> Implement pattern_set and pattern_clear for the pattern trigger's
> hw_pattern. A pattern is the one breathing cycle the hardware has,
> "0 rise brightness high brightness fall 0 low", which the software
> pattern trigger plays as the same breath, repeated forever.
>
> blink_set now clears the ramp times, so a blink after a pattern stays
> sharp.
