From: Preetham Chandru R <pchandru@xxxxxxxxxx> This adds bindings documentation for the AHCI controller on Tegra210 Signed-off-by: Preetham Chandru R <pchandru@xxxxxxxxxx> --- v4: * changed the commit message * changed 'sata-cold' reset to mandatory for t210 and t124 * Removed the regulators for T210 since these regulators will be enabled in phy driver. v3: * Add AUX register. v2: * change cml1, pll_e and phy regulators as optional for T210. --- .../bindings/ata/nvidia,tegra124-ahci.txt | 38 ++++++++++++++-------- 1 file changed, 25 insertions(+), 13 deletions(-) diff --git a/Documentation/devicetree/bindings/ata/nvidia,tegra124-ahci.txt b/Documentation/devicetree/bindings/ata/nvidia,tegra124-ahci.txt index 66c83c3..df4dc2c 100644 --- a/Documentation/devicetree/bindings/ata/nvidia,tegra124-ahci.txt +++ b/Documentation/devicetree/bindings/ata/nvidia,tegra124-ahci.txt @@ -1,20 +1,19 @@ -Tegra124 SoC SATA AHCI controller +Tegra SoC SATA AHCI controller Required properties : -- compatible : For Tegra124, must contain "nvidia,tegra124-ahci".
