From: Anil Kumar
Date: Wed Feb 20 2013 - 08:44:28 EST


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 (PMIC), MMC1, I2C1 and leds are added.

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

-Tested on Devkit8000.

For V4:
-Tiny nitpick.

For V3:
- Remove pin mux as done at device boot time by default.

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.
