   4 Subject: [PATCH] ARM: dts: BCM5301X: Specify PWM in the DT
   5
   6 The BCM53016 in the Meraki MR32 uses the on-chip PWM
   7 controller to drive a tri-color RGB LED. Since I plan
   8 to use the PWM, I made a label for the pwm's pinmux
   9 node. This way, it can be easily referenced.... And
  10 Also included a label for the i2c since I'm going to
  11 need it in the future too.
