[PATCHv2 00/11] Multiple fixes for Devkit8000

[PATCHv2 00/11] Multiple fixes for Devkit8000

[Thomas Weber]

These patches correct errors that were done while using the board code
from beagle board for Devkit8000. 

The Devkit8000 uses the TPS65930, an reduced version of the TWL4030. 
So not all power supplies from the TWL4030 are available.
The DSS2 do not need a VDVI any longer so it is removed. 
The definition of the supplies are changed to use the new REGULATOR_SUPPLY macro.
The pins for lcd and dvi powerdown are corrected.

Changes to v1:
 -remove the patches that only fix comments
 -expand the description of the patches

[Thomas Weber]

From: Kan-Ru Chen <kanru@0xlab.org>

This patch corrects the DVI-D output setup of Devkit8000

Devkit8000 has different DVI reset pin with the BeagleBoard.
On Devkit8000 the TWL4030 GPIO_7 is assigned to do the job.

[PATCHv2 04/11] OMAP2: Devkit8000: Setup LCD reset

[Thomas Weber]

From: Kan-Ru Chen <kanru@0xlab.org>

This patch corrects the LCD reset pin configuration.

Original code from early devkit8000 patch sets the TWL4030 GPIO_1
to EHCI_nOC and TWL4030_GPIO_MAX+1 to ledA. Indeed these two pins
are both LCD_PWREN. Setup the lcd reset_gpio properly so it can be
disabled when other display is turned on.

[PATCHv2 11/11] OMAP2: Devkit8000: Fix regulator for power supply

[Thomas Weber]

Devkit8000 uses the TPS65930 and not the TWL4030.
The TPS65930 uses only a subset of the power supplies
of the TWL4030.
