This patch adds the device tree node entries for exynos5420 SOC. Exynos5420 has a different version of DWMMC controller,so a new compatible string is used to distinguish it from the prior SOC's. This patch depends on mmc: dw_mmc: exynos: Add a new compatible string for exynos5420 changes since v5: 1.removed instance index from node name. 2.changed the node name to mshc. 3.changed the reg property value for mshc_2. changes since v4: 1.Droppped the bypass-smu binding property. 2.Used compatible string "samsung,exynos5250-dw-mshc" for controller instance which does not have SMU. changes since V3: 1.change fifo-depth size from 0x80 to 0x40 2.Move the below properties a.card-detect-delay b.samsung,dw-mshc-ciu-div c.samsung,dw-mshc-sdr-timing d.samsung,dw-mshc-ddr-timing from SOC dts to board dts file as suggested by Doug Anderson changes since V2: 1.dropped num-slots property from node as its not required if number of card slots available is 1. 2.Move the below properties a.fifo-depth b.card-detect-delay c.samsung,dw-mshc-ciu-div d.samsung,dw-mshc-sdr-timing e.samsung,dw-mshc-ddr-timing from board dts to SOC dts,as these are not board specific properties. 3.Updated the binding document exynos-dw-mshc.txt. changes since V1: 1.disable node by status = disabled in SOC file 2.enable node by status = okay in board specific file Signed-off-by: Yuvaraj Kumar C D <yuvaraj.cd@samsung.com> --- .../devicetree/bindings/mmc/exynos-dw-mshc.txt | 2 + arch/arm/boot/dts/exynos5420-smdk5420.dts | 33 +++++++++++++++++ arch/arm/boot/dts/exynos5420.dtsi | 39 ++++++++++++++++++++ 3 files changed, 74 insertions(+)
