This patchset is used to fix a host version register bug in the T4240-
R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 15 previous
version
patchsets had tried many methods but all of them were rejected by
reviewers.
Such as
????????- dts compatible method
????????- syscon method
????????- ifdef PPC method
????????- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only
available
method left now. This v11 patchset introduces the soc_device_match
interface in
soc driver.

The first four patches of Yangbo are to add the GUTS driver. This is used
to
register a soc device which contain soc version and revision information.
The other three patches introduce the soc_device_match method in soc
driver
and apply it on esdhc driver to fix this bug.

Thanks, applied on my mmc tree for next!

I noticed that some DT compatibles weren't documented, according to
checkpatch. Please fix that asap!

They are documented, in fsl/guts.txt (the file moved in patch 2/7):

?- compatible : Should define the compatible device type for
???global-utilities.
???Possible compatibles:
????????"fsl,qoriq-device-config-1.0"
????????"fsl,qoriq-device-config-2.0"
????????"fsl,<chip>-device-config"
????????"fsl,<chip>-guts"

Checkpatch doesn't understand compatibles defined in such a way.
