1* Broadcom SATA3 PHY 2 3Required properties: 4- compatible: should be one or more of 5 "brcm,bcm7425-sata-phy" 6 "brcm,bcm7445-sata-phy" 7 "brcm,iproc-ns2-sata-phy" 8 "brcm,iproc-nsp-sata-phy" 9 "brcm,phy-sata3" 10 "brcm,iproc-sr-sata-phy" 11 "brcm,bcm63138-sata-phy" 12- address-cells: should be 1 13- size-cells: should be 0 14- reg: register ranges for the PHY PCB interface 15- reg-names: should be "phy" and "phy-ctrl" 16 The "phy-ctrl" registers are only required for 17 "brcm,iproc-ns2-sata-phy" and "brcm,iproc-sr-sata-phy". 18 19Sub-nodes: 20 Each port's PHY should be represented as a sub-node. 21 22Sub-nodes required properties: 23- reg: the PHY number 24- phy-cells: generic PHY binding; must be 0 25 26Sub-nodes optional properties: 27- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port 28 This property is not applicable for "brcm,iproc-ns2-sata-phy", 29 "brcm,iproc-nsp-sata-phy" and "brcm,iproc-sr-sata-phy". 30 31- brcm,rxaeq-mode: string that indicates the desired RX equalizer 32 mode, possible values are: 33 "off" (equivalent to not specifying the property) 34 "auto" 35 "manual" (brcm,rxaeq-value is used in that case) 36 37- brcm,rxaeq-value: when 'rxaeq-mode' is set to "manual", provides the RX 38 equalizer value that should be used. Allowed range is 0..63. 39 40Example 41 sata-phy@f0458100 { 42 compatible = "brcm,bcm7445-sata-phy", "brcm,phy-sata3"; 43 reg = <0xf0458100 0x1e00>, <0xf045804c 0x10>; 44 reg-names = "phy"; 45 #address-cells = <1>; 46 #size-cells = <0>; 47 48 sata-phy@0 { 49 reg = <0>; 50 #phy-cells = <0>; 51 }; 52 53 sata-phy@1 { 54 reg = <1>; 55 #phy-cells = <0>; 56 }; 57 }; 58
