This patch series adds support for the Compulab CM-T335 board.
The board is based on TI Sitara AM3352/4 SoC and provides folowing features:
 - 128MB to 512MB DDR3
 - 128MB to 1GB NAND as a main storage
 - Micro SD/MMC card as a secondary storage
 - USB2.0 x4 host ports or USB2.0 x1 OTG port
 - Gigabit Ethernet, WiFi 802.11, Bluetooth, CAN bus, UART
 - LCD/DVI/LVDS display, touchscreen
 - Analog audio

  cm_t335: add cm_t335 board support
  cm_t335: add support for status LED
  cm_t335: add support for pca9555 i2c gpio extender
