-MediaTek Serial ATA controller
-
-Required properties:
- - compatible : Must be "mediatek,<chip>-ahci", "mediatek,mtk-ahci".
- When using "mediatek,mtk-ahci" compatible strings, you
- need SoC specific ones in addition, one of:
- - "mediatek,mt7622-ahci"
- - reg : Physical base addresses and length of register sets.
- - interrupts : Interrupt associated with the SATA device.
- - interrupt-names : Associated name must be: "hostc".
- - clocks : A list of phandle and clock specifier pairs, one for each
- entry in clock-names.
- - clock-names : Associated names must be: "ahb", "axi", "asic", "rbc", "pm".
- - phys : A phandle and PHY specifier pair for the PHY port.
- - phy-names : Associated name must be: "sata-phy".
- - ports-implemented : See ./ahci-platform.txt for details.
-
-Optional properties:
- - power-domains : A phandle and power domain specifier pair to the power
- domain which is responsible for collapsing and restoring
- power to the peripheral.
- - resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
- - reset-names : Associated names must be: "axi", "sw", "reg".
- - mediatek,phy-mode : A phandle to the system controller, used to enable
- SATA function.
-
-Example:
-
- sata: sata@1a200000 {
- compatible = "mediatek,mt7622-ahci",
- "mediatek,mtk-ahci";
- reg = <0 0x1a200000 0 0x1100>;
- interrupts = <GIC_SPI 233 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-names = "hostc";
- clocks = <&pciesys CLK_SATA_AHB_EN>,
- <&pciesys CLK_SATA_AXI_EN>,
- <&pciesys CLK_SATA_ASIC_EN>,
- <&pciesys CLK_SATA_RBC_EN>,
- <&pciesys CLK_SATA_PM_EN>;
- clock-names = "ahb", "axi", "asic", "rbc", "pm";
- phys = <&u3port1 PHY_TYPE_SATA>;
- phy-names = "sata-phy";
- ports-implemented = <0x1>;
- power-domains = <&scpsys MT7622_POWER_DOMAIN_HIF0>;
- resets = <&pciesys MT7622_SATA_AXI_BUS_RST>,
- <&pciesys MT7622_SATA_PHY_SW_RST>,
- <&pciesys MT7622_SATA_PHY_REG_RST>;
- reset-names = "axi", "sw", "reg";
