Hello,

This patch set adds support for Variscite OM44 series of system on modules and boards.

There weren't many comments on v1 of this patch set so I hope this can make it into 3.16. Changes since v2:
* Use OMAP IOPAD macros

Patch 1: Add support for the SoM itself and the reference carrier board. Together these make the VAR-STK-OM44 dev kit. Patch 2: Add support for VAR-DVK-OM44 which is just the STK with a LCD display.
Patch 3: Nodes for WLAN/BT support.
Patch 4: Add quirks so that WLAN can be used. Still waiting for proper DT bindings.

Since this patch set now uses the IOPAD macros a fix from Tony is need.
See: https://patchwork.kernel.org/patch/4025421/

Just noted that the macro won't work while was about to apply these, sorry. So we're back to either using the existing OMAP4_WKUP_IOPAD or raw offset from the padconf area unless you have some great macro ideas.

I see. I'll take another look at the macro's and see what I can come up with.

Note that patch 1 relies upon a patch from Tomi Valkeinen add hpd-gpio (hotplug detect) to the "hdmi-connector".

Patch 2 also relies upon a patch from Tomi that adds DT support to panel-dpi.

Maybe also leave out the DSS changes until Tomi has confirmed those?

I can split the patch set and put a patch with the DSS DT nodes at the end. Maybe this last patch can go through Tomi if he has a DSS DT branch. I don't want to drop it entirely from the patch set because some other people has expressed interest in testing it with full display and hdmi support.
