From: Preetham Ramchandra <redacted> This adds bindings documentation for the AHCI controller on Tegra210 Signed-off-by: Preetham Chandru R <redacted> --- v7: * For Aux register set drop the Tegra210 since this register set also works on Tegra124 * rephrase the sentence for cml1 clock * change the commit subject to include ahci-tegra * drop pll_e since CCF handles it automatically as CML1 is a child clock of it. 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 | 35 ++++++++++++++-------- 1 file changed, 22 insertions(+), 13 deletions(-)
