* Samsung AHCI SATA Controller
SATA nodes are defined to describe on-chip Serial ATA controllers.
Each SATA controller should have its own node.
Required properties:
- compatible : compatible list, contains "samsung,exynos5-sata"
- interrupts : <interrupt mapping for SATA IRQ>
- reg : <registers mapping>
- samsung,sata-freq : <frequency in MHz>
- phys : Must contain exactly one entry as specified
in phy-bindings.txt
- phy-names : Must be "sata-phy"
Optional properties:
- clocks : Must contain an entry for each entry in clock-names.
- clock-names : Shall be "sata" for the external SATA bus clock,
and "sclk_sata" for the internal controller clock.
Example:
sata@122f0000 {
compatible = "snps,dwc-ahci";
samsung,sata-freq = <66>;
reg = <0x122f0000 0x1ff>;
interrupts = <0 115 0>;
clocks = <&clock 277>, <&clock 143>;
clock-names = "sata", "sclk_sata";
phys = <&sata_phy>;
phy-names = "sata-phy";
};
