Subject: dt-bindings: backlight: rt4831: Add the new ocp level property
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=27e5c6546333bc7bbbb58b1a823ef21a6317b546;p=linux.git

dt-bindings: backlight: rt4831: Add the new ocp level property

Add 'richtek,bled-ocp-microamp' property to make it chooseable.

The wrong backlight ocp level may affect the backlight channel output
current smaller than configured.
