This patchset removes all uses of 'clk_type' member from the platform data of sdhci-s3c driver and adds device tree support for sdhci-s3c driver. This patchset has merged the following two patchsets submitted earlier into one patchset. [PATCH 0/3] mmc: sdhci-s3c: Remove 'clk_type' member from platform data [PATCH 0/3] mmc: sdhci-s3c: Add device tree support for Samsung's sdhci controller driver This patchset is rebased over the patches for sdhci clock lookup using generic names. 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 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. Fifth patch adds support for parsing of mmc host controller capabilities from a device node. This code would be reusable across other platforms as well. The last patch adds device tree based discovery for the sdhci-s3c driver. In this patchset, the comments from Rob Herring for the fifth patch in this series has been addressed. This patchset is based on the following tree. https://github.com/kgene/linux-samsung.git branch: next-samsung-dt Thomas Abraham (6): mmc: sdhci-s3c: Remove usage of clk_type member in platform data arm: exynos4: use 'exynos4-sdhci' as device name for sdhci controllers arm: samsung: remove all uses of clk_type member in sdhci platform data mmc: sdhci-s3c: Keep a copy of platform data and use it mmc: Add OF bindings support for mmc host controller capabilities mmc: sdhci-s3c: Add device tree support .../devicetree/bindings/mmc/linux-mmc-host.txt | 13 + .../devicetree/bindings/mmc/samsung-sdhci.txt | 75 +++++++ arch/arm/mach-exynos4/clock.c | 24 +- arch/arm/mach-exynos4/cpu.c | 5 + arch/arm/mach-exynos4/mach-armlex4210.c | 3 - arch/arm/mach-exynos4/mach-nuri.c | 3 - arch/arm/mach-exynos4/mach-origen.c | 2 - arch/arm/mach-exynos4/mach-smdk4x12.c | 2 - arch/arm/mach-exynos4/mach-smdkv310.c | 4 - arch/arm/mach-exynos4/mach-universal_c210.c | 2 - arch/arm/plat-samsung/devs.c | 4 - arch/arm/plat-samsung/include/plat/sdhci.h | 34 +++- arch/arm/plat-samsung/platformdata.c | 2 - drivers/mmc/core/host.c | 31 +++ drivers/mmc/host/sdhci-s3c.c | 231 +++++++++++++++++++- include/linux/mmc/host.h | 1 + 16 files changed, 386 insertions(+), 50 deletions(-) create mode 100644 Documentation/devicetree/bindings/mmc/linux-mmc-host.txt create mode 100644 Documentation/devicetree/bindings/mmc/samsung-sdhci.txt -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
