[PATCH 0/3] Add device tree support to AM33XX SoC

[AnilKumar Ch]

This patch series add device tree support for AM33XX SoC family.

Initialy Hiremath Vaibhav submitted a patch for AM33XX devices
based on omap3 family. Details at
http://marc.info/?t=132687107200002&r=1&w=2

AM33XX family is varied from omap3 family in these aspects
like memory maps, peripheral base addresses and configuration
parameters. In some cases we have to use a mix of omap3 and
omap4 parameters. So a seperate am33xx.dtsi file is created
for all the devices comes under am33xx family and revert of
above patch is required.

Two sepearte device tree source files are created (am335x-evm.dts
and am335x-bone.dts) to add support for AM335X EVM and BeagleBone
boards.

Linux booting is tested on AM335X-EVM and BeagleBone boards.

As that has not been merged yet, I'll just drop it and set up
a new devel-dt branch. Applying the reset into devel-dt.

Yeah, that's better.

Care to include it into you next pull request.

devel-dt branch is created but these patches are not pushed yet.

Let me know do you have any comments on the patches.

Oops, sorry yes looks like I only dropped the one you wanted
to revert but forgot to apply the new ones. Applied now to
devel-dt and pushed out.

[PATCH 2/4] arm/dts: Add initial DT support for AM33XX SoC family

[AnilKumar Ch]

Add device tree source include file for the AM33XX SoC family.
An additional .dtsi file is created to describe the generic
AM33XX CPU module like intc, ocp.

Actual selection of available peripherals is handled in seperate
.dts files using this am33xx.dtsi generic header file.

I realized that for mcspi and mmc, the compatible name supposed tobe close to
omap4-mcspi. 
These changes seems to went from my local branch, so could you please merge

I don't quite follow, do you mean you want to change some compatible names?
Your patch is just removing entries though?

Anyways, please just send a fix with a proper description and Signed-off-by
on top of the devel-dt branch.
