In this patchset, all uses of 'clk_type' member from the platform data are
removed from the sdhci-s3c driver and platform code. The clk_type is a SoC
specific information and not a board/machine specific information. Hence,
this
information can be more aptly represented using SoC specific driver data
in the
sdhci-s3c driver.

Hence all uses of 'clk_type' member in sdhci-s3c driver's platform data is
removed. In place of that, the sdhci host qurik
'SDHCI_QUIRK_NONSTANDARD_CLOCK'
is used to handle controllers that do not have a standard sdclk division
(like those in the exynos4 SoC's).

This is a pre-requisite for adding device tree support for sdhci-s3c
driver.
While migrating towards device tree support, retreving 'clk_type'
information
from device tree information does not seem correct and hence it has been
added
as SoC specific driver data. All this is handled in patches 1 to 3.

Patch 4 to 6 add device tree support for sdhci-s3c driver. The fourth
patch
derives the maximum transfer width host capability from the max_width
member
in platform data. The fifth patch modifies the sdhci-s3c driver to
mainatain
a local copy of the platform data, which makes it easier to add device
tree
support for the driver. The last patch adds device tree based discovery
for
the sdhci-s3c driver.

This patchset is based on the following tree.

Hi,

Looks ok to me and I'd like to pick this series in samsung tree with Chris'
ack.

Chris, is it ok? If you need to merge this in your tree, please let me know.
I will provide topic branch for it.

If any problems, please let me know.

Thanks.

Best regards,
Kgene.
