[v5,00/10] mips: Support for RTL9302C

Message

This series adds basic support for the RTL9302C reference board. Currently the
focus is on the CPU block stuff. I hope to get around to the DSA switch driver
eventually but this is a small start that lets me boot a mainline kernel on the
board I have. I initialiy started with code from openwrt but have paired it
down to just the clocksource driver and devicetree.

The first two patches in this series are fixing some complaints from make
dtbs_check for some existing realtek dts files. They can be applied on their
own if desired.

Chris Packham (10):
  mips: dts: realtek: use "serial" instead of "uart" in node name
  mips: dts: realtek: add device_type property to cpu node
  dt-bindings: vendor-prefixes: Add Cameo Communications
  dt-bindings: mips: realtek: Add rtl930x-soc compatible
  dt-bindings: timer: Add schema for realtek,otto-timer
  dt-bindings: interrupt-controller: realtek,rtl-intc: Add rtl9300-intc
  clocksource: realtek: Add timer driver for rtl-otto platforms
  mips: select REALTEK_OTTO_TIMER for Realtek platforms
  mips: generic: add fdt fixup for Realtek reference board
  mips: dts: realtek: Add RTL9302C board
