1 STMicroelectronics STi MIPHY365x PHY binding
2 ============================================
3
4 This binding describes a miphy device that is
5 for SATA and PCIe.
6
7 Required properties (controller (parent) node)
8 - compatible : Should be "st,miphy365x-phy"
9 - st,syscfg : Phandle / integer array prop
10 containing the miphy registe
11 an entry for each port sub-n
12 register offset inside the s
13
14 Required nodes : A sub-node is required for
15 provides. Address range inf
16 'reg' and 'reg-names' prope
17 nodes to describe the contr
18 are translated by the drive
19
20 Required properties (port (child) node):
21 - #phy-cells : Should be 1 (See second exam
22 Cell after port phandle is d
23 - PHY_TYPE_SATA
24 - PHY_TYPE_PCI
25 - reg : Address and length of regist
26 "reg-names"
27 - reg-names : The names of the register ad
28 registers filled in "reg":
29 - sata: For SATA dev
30 - pcie: For PCIe dev
31
32 Optional properties (port (child) node):
33 - st,sata-gen : Generation of locally
34 are {1,2,3). If not su
35 be expected
36 - st,pcie-tx-pol-inv : Bool property to inver
37 - st,sata-tx-pol-inv : Bool property to inver
38
39 Example:
40
41 miphy365x_phy: miphy365x@fe382000 {
42 compatible = "st,miphy365
43 st,syscfg = <&syscfg_rea
44 #address-cells = <1>;
45 #size-cells = <1>;
46 ranges;
47
48 phy_port0: port@fe382000 {
49 reg = <0xfe382000 0x10
50 reg-names = "sata", "p
51 #phy-cells = <1>;
52 st,sata-gen = <3>;
53 };
54
55 phy_port1: port@fe38a000 {
56 reg = <0xfe38a000 0x10
57 reg-names = "sata", "p
58 #phy-cells = <1>;
59 st,pcie-tx-pol-inv;
60 };
61 };
62
63 Specifying phy control of devices
64 =================================
65
66 Device nodes should specify the configuration
67 property, containing a phandle to the phy port
68
69 Example:
70
71 #include <dt-bindings/phy/phy.h>
72
73 sata0: sata@fe380000 {
74 ...
75 phys = <&phy_port0 PHY_TY
76 ...
77 };
