Hi all,
Now that pinctrl-single driver is merged, this series enables
pinctrl for omap2/3/4.
Regards,
Tony

The extra serial port is not available on 34xx. And the current
omap3-beagle.dts file is for omap3-beagle-xm.dts as it lists 512MB
of memory.
Please somebody submit a new omap3-beagle.dts for the original 34xx
BeagleBoard after testing it properly.

Indeed, my Beagle is in fact a xM :-)
It is too bad that we do have to duplicate the DTS file for all the board variants. Peter already did that for pandaES and at that time I was wondering if this was needed or not.
That being said, I'm not sure we have any good way to handle two boards using the same DTS. It means that will we will have to rely on the bootloader now to select the proper DTB.
Please not that's I'm queuing a bunch of OMAP2/3/4/5/AM33XX for you, so you might have to rebase that one on top.
The branch is there.
git://git.kernel.org/pub/scm/linux/kernel/git/bcousson/linux-omap-dt.git for_3.7/dts
I'm still waiting for a couple of AM33xx pinmux patches from Anil that should re acked by some folks who know that (like you :-)).
I'll send you the pull request next week.

Benoit

* [PATCH 2/5] arm/dts: Add pinctrl driver entries for omap2/3/4

Add pinctrl driver entries for omap2+. These all use
the generic pinctrl-single driver for the padconf
registers.
Note that as 2420 and 2430 have different padmux
registers, we now need to include omap2420.dtsi from
omap2420-h4.dts.

Request pins using pinctrl framework. Only show a warning
on error as some boards set the pins in the bootloader
even if CONFIG_PINCTRL is enabled.

Greg, this patch should be OK for you to pick, it should not break
anything even if pinctrl is not available yet. Let me know if it
needs rebasing on top of other things you've queued for omap-serial.

Tony

Hmm the tty-next fails to build right now for omaps:
drivers/tty/serial/omap-serial.c: In function ‘serial_omap_set_mctrl’:
drivers/tty/serial/omap-serial.c:514: error: ‘struct uart_omap_port’ has no member named ‘DTR_gpio’
Maybe check how you want to fix that first? I can then update
my patch for tty-next.
Regards,
Tony
