+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.

+        The Serial setting is 115200-8-N-1. The board has a populated
+        right angle 1x4 0.1" pinheader.
+        The pinout is: VCC, RX, TX, GND.
+
+Odd stuff:
+       - uart0 clock frequency is 62.5 MHz.
+       - The LEDs are labeled as SYS-LED1 through SYS-LED3
+         because of the silkscreen on the PCB.
+       - the original u-boot has been compiled with most functions
+         and commands disabled. The u-boot env isn't setup properly
+         either and as a result, the bcm47xxpart probing is not
+         working. Hence, the nand partitions are specified through a
+         "fixed-partition" binding.
+       - The "WICED SMART(TM)" Bluetooth LE 4.0 BCM20732 chip is
+         connected to uart2 of the SoC. The BCM20732 does not
+         provide a HCI. So the linux' bluetooth stack is useless.
+         The mock-up node with the compatible binding and
+         enable-gpios property is provided solely as documentation.

-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.

-add support for the Cisco Meraki MR32.

-The unit was donated by Chris Blake. Thank you!

-
-SERIAL:
-       WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
-        The Serial setting is 115200-8-N-1. The board has a populated
-        right angle 1x4 0.1" pinheader.
-        The pinout is: VCC, RX, TX, GND.
-
-Odd stuff:
-       - uart0 clock frequency is 62.5 MHz.
-       - The LEDs are labeled as SYS-LED1 through SYS-LED3
-         because of the silkscreen on the PCB.
-       - the original u-boot has been compiled with most functions
-         and commands disabled. The u-boot env isn't setup properly
-         either and as a result, the bcm47xxpart probing is not
-         working. Hence, the nand partitions are specified through a
-         "fixed-partition" binding.
-       - The "WICED SMART(TM)" Bluetooth LE 4.0 BCM20732 chip is
-         connected to uart2 of the SoC. The BCM20732 does not
-         provide a HCI. So the linux' bluetooth stack is useless.
-         The mock-up node with the compatible binding and
-         enable-gpios property is provided solely as documentation.
