Signed-off-by: Yuvaraj Kumar C D --- Changes since V6:none Changes since V5:none Changes since V4: 1.Used the new phandle "sata_phy_i2c" in the DT entry. 2.Updated binding document. Changes since V3: 1.Moved the binding info to the /bindings/phy/ Changes since V2: 1.Used syscon interface to PMU handling. 2.Changed "sata-phy-i2c" to "exynos-sataphy-i2c". Changes since V1: 1.Minor changes to node name convention. 2.Updated binding document. .../devicetree/bindings/ata/exynos-sata-phy.txt | 14 -------- .../devicetree/bindings/ata/exynos-sata.txt | 25 +++++++++----- .../devicetree/bindings/phy/samsung-phy.txt | 36 ++++++++++++++++++++ arch/arm/boot/dts/exynos5250-arndale.dts | 11 ++++++ arch/arm/boot/dts/exynos5250-smdk5250.dts | 8 ++--- arch/arm/boot/dts/exynos5250.dtsi | 17 ++++++--- 6 files changed, 78 insertions(+), 33 deletions(-) delete mode 100644 Documentation/devicetree/bindings/ata/exynos-sata-phy.txt diff --git a/Documentation/devicetree/bindings/ata/exynos-sata-phy.txt b/Documentation/devicetree/bindings/ata/exynos-sata-phy.txt deleted file mode 100644 index 37824fa..0000000 --- a/Documentation/devicetree/bindings/ata/exynos-sata-phy.txt +++ /dev/null @@ -1,14 +0,0 @@ -* Samsung SATA PHY Controller - -SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers. -Each SATA PHY controller should have its own node. - -Required properties: -- compatible : compatible list, contains "samsung,exynos5-sata-phy" -- reg : - -Example: - sata@ffe07000 { - compatible = "samsung,exynos5-sata-phy"; - reg = <0xffe07000 0x1000>; - }; diff --git a/Documentation/devicetree/bindings/ata/exynos-sata.txt b/Documentation/devicetree/bindings/ata/exynos-sata.txt index 0849f10..b2adb1f 100644 --- a/Documentation/devicetree/bindings/ata/exynos-sata.txt +++ b/Documentation/devicetree/bindings/ata/exynos-sata.txt @@ -4,14 +4,21 @@ SATA nodes are defined to describe on-chip Serial ATA controllers.
