[PATCH 0/4] OMAPDSS: sharp-ls037v7dw01 DT support

[Tomi Valkeinen]

Hi,

These are slightly reworked versions of the patches Tony sent:

* Split the DT doc into separate patch
* Handle errors from gpio functions
* Remove QVGA support
* Removed the change to arch/arm/mach-omap2/display.c. I'll add that to my
  patch which moves the conversion code to omapdss. Note that if you test this
  version, you need to add the panel name to the conversion list for now.
* Set MO gpio GPIO_ACTIVE_HIGH in omap3-evm-common.dtsi
* Set the GPIO default values the same way for DT and non-DT versions.

Tony, I removed the QVGA support as it was a new feature, not supported by the
non-DT version. Also, I don't think it should be done as you had implemented
it, but rather either have a flag in the DT data in case the pin is hardwired
in the hardware, or let the user select the mode at runtime.

Also, I didn't quite understand the implementation. You had set initial values
in the driver for MO and RESB differently than on the non-DT version. Was that
on purpose?

You said in a comment: "The LCD is sideways, so we want the VGA mode instead of
QVGA mode.". Why is that? How does the resolution affect the orientation?

With my version, the panel (should) always be in VGA mode, like the non-DT
version does.

Only compile tested, I don't have boards with the panel.

 Tomi
