[PATCHv2 0/2] misc Devkit8000 fixes

[Thomas Weber]

Here is a set of misc fixes for the devkit8000.

The only really notable one is the lcd enable gpio fix. It gets rid
of some nasty low level twl4030 calls and replaces them with generic gpio
calls. It also fixes a bug where the screen would not turn off when
blanking.

Changes from v1: 
	Pull the indention fix into "Change lcd power pin".
	Change the pin for lcd pwren.
	Fix the pullup/pulldown configuration after lcd prwen correction.

[PATCHv2 1/2] OMAP3: Devkit8000: Change lcd power pin

[Thomas Weber]

The reset_gpio pin for lcd is connected with TWL4030 LedA.
TWL4030 GPIO.1 has a not connected resistor.

Fix indention issue. The comment line uses 8 whitespaces. 
Replaced with one tabulator.

[PATCHv2 2/2] omap3: devkit8000: fix tps65930 pullup/pulldown configuration

[Thomas Weber]

From: Daniel Morsing <daniel.morsing@gmail.com>

gpio7 on the tps65930 is used as an output on the devkit8000 and gpio1
is not connected. Remove gpio7 and change gpio1 to pulldown

Hey Thomas.

Only real issue I can see is that fact that the commit message doesn't
mention the removal of the low level twl4030 calls. They are essentially
non-functional in their current state and mentioning that and why they
were removed would help in any future code archaeology.

Regards,
Daniel
