As part of testing ahci_st driver working on stih407 I noticed several things wrong in the DT documentation: - 1) Compatible string doesn't match the driver code 2) pwr-rst reset isn't documented (but exists in the driver) 3) some whitespace issues (spaces not tabs) Also add in a stih407 family example into the doc.

STMicroelectronics STi SATA controller
|
|
|
|
This binding describes a SATA device.
|
|
|
|
Required properties:
|
|
- compatible : Must be "st,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 : The phandle for the clock
|
|
- clock-names : Associated name must be; "ahci_clk"
|
|
- phys : The phandle for the PHY port
|
|
- phy-names : Associated name must be; "ahci_phy"
|
|
|
|
Optional properties:
|
|
- resets : The power-down, soft-reset and power-reset lines of SATA IP
|
|
- reset-names : Associated names must be; "pwr-dwn", "sw-rst" and "pwr-rst"
|
|
|
|
Example:
|
|
|
|
/* Example for stih416 */
|
|
sata0: sata@fe380000 {
|
|
compatible = "st,ahci";
|
|
reg = <0xfe380000 0x1000>;
|
|
interrupts = <GIC_SPI 157 IRQ_TYPE_NONE>;
|
|
interrupt-names = "hostc";
|
|
phys = <&phy_port0 PHY_TYPE_SATA>;
|
|
phy-names = "ahci_phy";
|
|
resets = <&powerdown STIH416_SATA0_POWERDOWN>,
|
|
<&softreset STIH416_SATA0_SOFTRESET>;
|
|
reset-names = "pwr-dwn", "sw-rst";
|
|
clocks = <&clk_s_a0_ls CLK_ICN_REG>;
|
|
clock-names = "ahci_clk";
