Must be 'ceva,ahci-1v84'. - clocks: Input clock specifier. Refer to common clock bindings. - interrupts: Interrupt specifier. Refer to interrupt binding. - ceva,p0-cominit-params: OOB timing value for COMINIT parameter for port 0. - ceva,p1-cominit-params: OOB timing value for COMINIT parameter for port 1. The fields for the above parameter must be as shown below: ceva,pN-cominit-params = /bits/ 8 <CIBGMN CIBGMX CIBGN CINMP>; CINMP : COMINIT Negate Minimum Period. CIBGN : COMINIT Burst Gap Nominal. CIBGMX: COMINIT Burst Gap Maximum. CIBGMN: COMINIT Burst Gap Minimum. - ceva,p0-comwake-params: OOB timing value for COMWAKE parameter for port 0. - ceva,p1-comwake-params: OOB timing value for COMWAKE parameter for port 1. The fields for the above parameter must be as shown below: ceva,pN-comwake-params = /bits/ 8 <CWBGMN CWBGMX CWBGN CWNMP>; CWBGMN: COMWAKE Burst Gap Minimum. CWBGMX: COMWAKE Burst Gap Maximum. CWBGN: COMWAKE Burst Gap Nominal. CWNMP: COMWAKE Negate Minimum Period. - ceva,p0-burst-params: Burst timing value for COM parameter for port 0. - ceva,p1-burst-params: Burst timing value for COM parameter for port 1. The fields for the above parameter must be as shown below: ceva,pN-burst-params = /bits/ 8 <BMX BNM SFD PTST>; BMX: COM Burst Maximum. BNM: COM Burst Nominal. SFD: Signal Failure Detection value. PTST: Partial to Slumber timer value. - ceva,p0-retry-params: Retry interval timing value for port 0. - ceva,p1-retry-params: Retry interval timing value for port 1. The fields for the above parameter must be as shown below: ceva,pN-retry-params = /bits/ 16 <RIT RCT>; RIT: Retry Interval Timer. RCT: Rate Change Timer. Optional properties: - ceva,broken-gen2: limit to gen1 speed instead of gen2. - phys: phandle for the PHY device - resets: phandle to the reset controller for the SATA IP Examples: ahci@fd0c0000 { compatible = "ceva,ahci-1v84"; reg = <0xfd0c0000 0x200>; interrupt-parent = <&gic>; interrupts = <0 133 4>; clocks = <&clkc SATA_CLK_ID>; ceva,p0-cominit-params = /bits/ 8 <0x0F 0x25 0x18 0x29>; ceva,p0-comwake-params = /bits/ 8 <0x04 0x0B 0x08 0x0F>; ceva,p0-burst-params = /bits/ 8 <0x0A 0x08 0x4A 0x06>; ceva,p0-retry-params = /bits/ 16 <0x0216 0x7F06>; ceva,p1-cominit-params = /bits/ 8 <0x0F 0x25 0x18 0x29>; ceva,p1-comwake-params = /bits/ 8 <0x04 0x0B 0x08 0x0F>; ceva,p1-burst-params = /bits/ 8 <0x0A 0x08 0x4A 0x06>; ceva,p1-retry-params = /bits/ 16 <0x0216 0x7F06>; ceva,broken-gen2; phys = <&psgtr 1 PHY_TYPE_SATA 1 1>; resets = <&zynqmp_reset ZYNQMP_RESET_SATA>; }; |
