1MediaTek Serial ATA controller 2 3Required properties: 4 - compatible : Must be "mediatek,<chip>-ahci", "mediatek,mtk-ahci". 5 When using "mediatek,mtk-ahci" compatible strings, you 6 need SoC specific ones in addition, one of: 7 - "mediatek,mt7622-ahci" 8 - reg : Physical base addresses and length of register sets. 9 - interrupts : Interrupt associated with the SATA device. 10 - interrupt-names : Associated name must be: "hostc". 11 - clocks : A list of phandle and clock specifier pairs, one for each 12 entry in clock-names. 13 - clock-names : Associated names must be: "ahb", "axi", "asic", "rbc", "pm". 14 - phys : A phandle and PHY specifier pair for the PHY port. 15 - phy-names : Associated name must be: "sata-phy". 16 - ports-implemented : See ./ahci-platform.txt for details. 17 18Optional properties: 19 - power-domains : A phandle and power domain specifier pair to the power 20 domain which is responsible for collapsing and restoring 21 power to the peripheral. 22 - resets : Must contain an entry for each entry in reset-names. 23 See ../reset/reset.txt for details. 24 - reset-names : Associated names must be: "axi", "sw", "reg". 25 - mediatek,phy-mode : A phandle to the system controller, used to enable 26 SATA function. 27 28Example: 29 30 sata: sata@1a200000 { 31 compatible = "mediatek,mt7622-ahci", 32 "mediatek,mtk-ahci"; 33 reg = <0 0x1a200000 0 0x1100>; 34 interrupts = <GIC_SPI 233 IRQ_TYPE_LEVEL_HIGH>; 35 interrupt-names = "hostc"; 36 clocks = <&pciesys CLK_SATA_AHB_EN>, 37 <&pciesys CLK_SATA_AXI_EN>, 38 <&pciesys CLK_SATA_ASIC_EN>, 39 <&pciesys CLK_SATA_RBC_EN>, 40 <&pciesys CLK_SATA_PM_EN>; 41 clock-names = "ahb", "axi", "asic", "rbc", "pm"; 42 phys = <&u3port1 PHY_TYPE_SATA>; 43 phy-names = "sata-phy"; 44 ports-implemented = <0x1>; 45 power-domains = <&scpsys MT7622_POWER_DOMAIN_HIF0>; 46 resets = <&pciesys MT7622_SATA_AXI_BUS_RST>, 47 <&pciesys MT7622_SATA_PHY_SW_RST>, 48 <&pciesys MT7622_SATA_PHY_REG_RST>; 49 reset-names = "axi", "sw", "reg"; 50 mediatek,phy-mode = <&pciesys>; 51 };
