uevm is the official board supported for OMAP5 soc in the mainline.
This series renames the board dts file for OMAP5 accordingly and cleans
up the same. Also a few additional device DT entry updates are done.
This is on top of the below branch
git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git
for_3.11/dts
Boot tested on omap5-uevm after pulling in the data from below place
git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux.git
HWMOD DATA: for_3.11/omap5_data_files
CLOCK DATA: out_of_tree/omap5_clk_data

The uevm is the official board supported for the OMAP5 soc
in mainline. The uevm has an OMAP5432 with a DDR3 memory.
Renaming the board dts file and adding the following cleanups.
* There are no devices connected on I2C 2,3,4 buses. So remove
the pinmux data for the same.
* DDR3 memory is used in the uevm. Neither DVFS or temperature
polling is supported with DDR3. So remove the DDR3 device and
emif nodes.
* Keypad is not supported on uevm. So remove the device node.

Comments are redundant with the constants, so maybe you can leave this
part out.
Same for a few others below.

Mismatch between constants and comments, which mode should it be?

I guess that here you can replace '0' with GIC_SPI.

Ok, I agree here for attributes like pulls, i/o etc, comments are now not required.
But comment is still good to describe just the mux mode functionality ?
One module will use different pins, like data, clk, gpios, etc. Just MUX_MODEX does not
complete it..

Yes, the 'usbb2_hsic_strobe' part must stay, only 'INPUT | MODE 0'
should be removed
from comments.

s/corrected/removed/. This will avoid this kind of inconsistency.

Hi Sricharan,
Thanks for sending this, but some parts are outdated. See below.

clock_alias node is not required. Instead we need to rely on proper clock binding
and provide reference to the clock phandle in the PHY node.
as an example please see here
https://lkml.org/lkml/2013/4/19/124
However this clock binding technique is still under discussion/transition.
https://patchwork.kernel.org/patch/2541331/
So, I suggest you leave the auxclk1 part out for now and we can get it in later once
the clock binding stuff is sorted out. The side effect of this is that PORT 2 (i.e. USB Hub)
will not work. USB Ethernet should still work IMO.
cheers,

Roger was suggesting to remove this for now. Posted

Are you suggesting to go with your clock-binding patch ?

you cannot. Mike has already rejected that approach and I have dropped
that series and wont be following up.
See discussion https://patchwork.kernel.org/patch/2541331/
instead the new approach being discussed
https://patchwork.kernel.org/patch/2657351/ and related discussions is
the way to go.
That said, it practically blocks introduction of all code that depend on
dts nodes :(, no matter how I dont like being blocked and my many series
delayed, I believe Mike, Tero, Rajendra are doing the right architecture
and we should wait for it's upstream introduction.
That is just my 2 cents.

Thanks for the details. So dropping the alias for now, should be fine.

Booting omap5 uevm results in the following error
"did not get pins for uart error: -19"
This happens because omap5 uevm dts file is not adapted to use uart through pinctrl
framework. Populating uart pinctrl data to get rid of the error.

* [PATCH 1/4] ARM: dts: omap5: Rename omap5-evm to omap5-uevm
@ 2013-06-05 6:54 Sricharan R

From: Sricharan R @ 2013-06-05 6:54 UTC (permalink / raw)
To: linux-arm-kernel
The uevm is the official board supported for the OMAP5 soc
in mainline. The uevm has an OMAP5432 with a DDR3 memory.
Renaming the board dts file and adding the following cleanups.
* There are no devices connected on I2C 2,3,4 buses. So remove
the pinmux data for the same.
* DDR3 memory is used in the uevm. Neither DVFS or temperature
polling is supported with DDR3. So remove the DDR3 device and
emif nodes.
* Keypad is not supported on uevm. So remove the device node.
