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.
