[PATCH 0/8] MXC: mach-mx31_3ds: Patch series that enable the support for Freescale i.MX31 3-Stack development board.

[Alberto Panizzo]

This series build the mainline architecture support for the Freescale i.MX31 3-Stack 
development board since all the drivers needed are merged in mainline from
the first 2.6.34 release candidate.

[PATCH 1/8] MXC: mach-mx31_3ds: Update variable names over recent mach name modification.

[PATCH 2/8] MXC: mach-mx31_3ds: Add support for on board NAND Flash.

[PATCH 3/8] MXC: mach-mx31_3ds: Add SPI1 device support.

[PATCH 4/8] MXC: mach-mx31_3ds: add support for freescale mc13783 power management device.

[PATCH 5/8] MXC: mach-mx31_3ds: Add support for SD card slot in the personality board.

[PATCH 6/8] MXC: mach-mx31_3ds: Add support for framebuffer and lcd.

[PATCH 7/8] MXC: mach-mx31_3ds: Add support for the keypad.

[PATCH 8/8] MXC: mach-mx31_3ds: enable mc13783 touchscreen interface.

Comments and/or suggestion are welcome.

Best Regards,

-- 
Alberto!

        Be Persistent!

This code looks wrong - the MMC core is requesting voltage ranges but
these are being non-linearly translated into specific voltages.  I
rather suspect that the standard mmc_regulator_set_ocr() function ought
to be able to cope with this, in conjunction with a regulator constraint
limiting the minimum voltage to 1.8V.  If not, some comments explaining
what's going on would really help.

Use dev_name, not dev.

I think the driver should handle the regulator stuff, not the platform.
drivers/mmc/host/pxamci.c looks like a good example.

[PATCH 7/8] MXC: mach-mx31_3ds: Add support for the keypad.

Hi


Sascha, perhaps it's time to apply this patch now? I was very close to submit a very similar patch a few moments ago (based on the current Linus git tree) but found this post in the archive.

I apologize for my delay in serving the issues raised in this thread.
Mangus, if you solve the problem (regulators handling support in imxmmc
as pxamci do) you could then post an acceptable version of this patch.
It is easy, really a bit of lines, but I do not have time now...

Then the rest of the thread can be rebased and applied.

Regards,
Alberto!

I had only the keypad-patch in mind, I have not worked with, or plan to do so, with SD-card or MMC.
The keypad patch should be ready to be appled, I didn't see any comments on that.

This patch combines 3ds platform support with the mx3 support. Can you
please send a patch with mx3 support only?

Sorry for overlaps.
Soon the two divided patches.
