Anil Kumar - Feb. 10, 2013, 4:05 p.m.
DevKit8000 is a beagle board clone from Timll, sold by
armkits.com. The DevKit8000 has RS232 serial port, LCD, DVI-D,
S-Video, Ethernet, SD/MMC, keyboard, camera, SPI, I2C, USB and
JTAG interface.

This patch adds the basic DT support for devkit8000. At this time, Information
of twl4030, MMC1, I2C1, leds and there pim mux information are added.

 -This patch is based on top of kernel 3.8-rc5.

 -Tested on Devkit8000.

For V2:

 -Change model name as "TimLL OMAP3 Devkit8000"
 -Change compatible as "timll,omap3-devkit8000"
 -Doing i2c1 pinmux default with pinctrl-single driver instead of i2c1
  driver probe time.
