[PATCH 0/4] MIPS: CI20: DTS: Add nodes to Creator CI20 board

[PATCH 0/4] MIPS: CI20: DTS: Add nodes to Creator CI20 board

[Alexandre GRIVEAUX]

Attemping to make my CI20 more usefull than a paperweight, I add nodes to Devicetree, at this time:

- The IW8103 need some work to stay alive because power seem to turn off.
- The leds patch lack of correct option in ci20_defconfig.
- The Cpu patch isn't usefull without SMP support of jz4780.

  MIPS: CI20: DTS: Add IW8103 Wifi + bluetooth
  MIPS: CI20: DTS: Add Leds
  MIPS: JZ4780: DTS: Add CPU nodes
