[0/6] 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.

Chris Packham (6):
  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: generic: add fdt fixup for Realtek reference board
  mips: dts: realtek: Add RTL9302C board
