[PATCH v3 3/8] ARM: shmobile: simplify armadillo800eva and kzm9g Kconfig dependencies

From: Guennadi Liakhovetski <hidden>
Date: 2013-01-23 16:37:46 

Reference kernel configurations for armadillo800eva and kzm9g boards do not
have to depend on their respective "legacy" configurations, doing device
instantiation in .c, they can be configured and built independently.

[PATCH v3 7/8] ARM: shmobile: completely switch MMC interfaces on mackerel-reference to DT

From: Guennadi Liakhovetski <hidden>
Date: 2013-01-23 16:37:50 

Switch MMCIF, SDHI0 and SDHI2 to complete DT initialisation: use DT
bindings to configure interface pins, card-detect GPIOs, various
interface configuration parameters. Notice, since MMCIF and SDHI1 share
the same card slot, both devices cannot be successfully probed
simultaneously: they both would try to get the card-detection GPIO and only
one would succeed. Ideally it should be possible to let the user decide
which device to enable by, possibly, patching the DT at run-time. As long as
this is unsupported, we choose to enable MMCIF and remove SDHI1 from DT
completely.

[PATCH v3 8/8] ARM: shmobile: completely switch MMC interfaces on armadillo800eva-reference to DT

From: Bastian Hecht <hidden>
Date: 2013-02-18 19:10:35 

Hello,

I'm looking for a branch to test out my new SCI DT version on my
Armadillo. I saw that topic/intc-of features the armadillo-reference
implementation so I wanted to use that. But "make dtbs" fails with:

Error: arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts:152.2-3
label or path, 'gpio', not found
FATAL ERROR: Syntax error parsing input tree

The error is introduced by this commit. I'm unsure if it is the patch
itself or the branch stacking though.

Thanks,

 Bastian

[PATCH v3 8/8] ARM: shmobile: completely switch MMC interfaces on armadillo800eva-reference to DT

From: Bastian Hecht <hidden>
Date: 2013-02-18 19:34:43 

Hi,

I got out of place by 1 commit in the intc-of branch:
It's "ARM: shmobile: move pin configuration on
armadillo800eva-reference to DT" not "ARM: shmobile: completely switch
MMC interfaces on armadillo800eva-reference to DT" that breaks "make
dtbs".

Thanks,

 Bastian

[PATCH v3 8/8] ARM: shmobile: completely switch MMC interfaces on armadillo800eva-reference to DT

Hi,

I got out of place by 1 commit in the intc-of branch:
It's "ARM: shmobile: move pin configuration on
armadillo800eva-reference to DT" not "ARM: shmobile: completely switch
MMC interfaces on armadillo800eva-reference to DT" that breaks "make
dtbs".
Could you please try the topic/all+next branch? It should contain all 
other branches and as such be the most complete one.

Thanks
Guennadi

Thanks,

 Bastian

Hello,

I'm looking for a branch to test out my new SCI DT version on my
Armadillo. I saw that topic/intc-of features the armadillo-reference
implementation so I wanted to use that. But "make dtbs" fails with:

Error: arch/arm/boot/dts/r8a7740-armadillo800eva-reference.dts:152.2-3
label or path, 'gpio', not found
FATAL ERROR: Syntax error parsing input tree

The error is introduced by this commit. I'm unsure if it is the patch
itself or the branch stacking though.

Thanks,

 Bastian

bindings to configure regulators, interface pins, card-detect GPIOs,
various interface configuration parameters.

Oh great, thanks for pointing out the correct branch to me! This one
looks good for my testing purposes.

Hi,

I got out of place by 1 commit in the intc-of branch:
It's "ARM: shmobile: move pin configuration on
armadillo800eva-reference to DT" not "ARM: shmobile: completely switch
MMC interfaces on armadillo800eva-reference to DT" that breaks "make
dtbs".
Thanks for pointing that out.

I have resolved this problem by rebasing the topic/intc-of branch
on a merge that includes the topic/pinmux branch. topic/pinmux includes
the following patch which provides 'gpio'.

* ARM: shmobile: r8a7740: Add pin control device in device tree

Could you please try the topic/all+next branch? It should contain all
other branches and as such be the most complete one.
Yes, it is the most complete one.

Oh great, thanks for pointing out the correct branch to me! This one
looks good for my testing purposes.
