to make multicolor PWM LEDs behavior more consistent with vendor

sorry, but that is definitly not a valid reason.
I see. I'll not change it.
A devicetree does describe actual hardware and is not a space for
configuration choices. So that whole notion to "match a kernel"
is not correct.
Looking at
https://wiki.radxa.com/Rock3/CM/CM3I/E25/getting_started
the specification table clearly designates the board's LED as
"RGB LED" - so one LED and multicolor .
I understand following behavior is not possible on mainline.
https://github.com/radxa-pkg/rsetup/blob/main/config/00-rgb0-rainbow.conf
this is not what we(Radxa) want, but we need to follow the rule.
(btw wiki.radxa.com is outdated, it's not used anymore)
Your Radxa vendor kernel and whatever you have *MUST* align to the
upstream, not the other way. The upstream is the correct source of doing
things, not the other way.
could you tell me how to make rainbow color effect with
"pwm-leds-multicolor" driver?
as far as I know, "pattern" trigger can change (only) brightness, not color.
