X-Git-Tag: v5.10.7~1320^2~48^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ea4b29d149586667d96767f1fc8e57ee942c1b0;p=platform%2Fkernel%2Flinux-rpi.git

ARM: dts: BCM5301X: Specify PWM in the DT

The BCM53016 in the Meraki MR32 uses the on-chip PWM
controller to drive a tri-color RGB LED. Since I plan
to use the PWM, I made a label for the pwm's pinmux
node. This way, it can be easily referenced.... And
Also included a label for the i2c since I'm going to
need it in the future too.
