This patchset adds support for sdhci controller on S5P6440 and S5P6450.
Since this patchset is based on "mmc: sdhci-s3c: Rework platform data
and add device tree support" clk_type member has been removed from
platform data.
This patchset depends on the patchs:
ARM: S5P64X0: Modified files for SPI consolidation work.
mmc: sdhci-s3c: Rework platform data and add device tree support.
Rajeshwari Shinde (3):
ARM: S5P64X0: Add HSMMC setup for host Controller
ARM: S5P64X0: Add lookup of sdhci-s3c clocks using generic names
ARM: S5P64X0: Enable SDHCI support

Hi Rajeshwari,
I need to sort out your this patches and Thomas' sdhci dt patches.
And it's merge window, so will be back on this after that.
Thanks.
Best regards,
Kgene.
