Subject: [PATCH] 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.
