1 * Qualcomm Technologies Inc Universal Flash Storage (UFS) PHY
3 UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
4 Each UFS PHY node should have its own node.
6 To bind UFS PHY with UFS host controller, the controller node should
7 contain a phandle reference to UFS PHY node.
10 - compatible : compatible list, contains one of the following -
11 "qcom,ufs-phy-qmp-20nm" for 20nm ufs phy,
12 "qcom,ufs-phy-qmp-14nm" for legacy 14nm ufs phy,
13 "qcom,msm8996-ufs-phy-qmp-14nm" for 14nm ufs phy
14 present on MSM8996 chipset.
15 - reg : should contain PHY register address space (mandatory),
16 - reg-names : indicates various resources passed to driver (via reg proptery) by name.
17 Required "reg-names" is "phy_mem".
18 - #phy-cells : This property shall be set to 0
19 - vdda-phy-supply : phandle to main PHY supply for analog domain
20 - vdda-pll-supply : phandle to PHY PLL and Power-Gen block power supply
21 - clocks : List of phandle and clock specifier pairs
22 - clock-names : List of clock input name strings sorted in the same
23 order as the clocks property. "ref_clk_src", "ref_clk",
24 "tx_iface_clk" & "rx_iface_clk" are mandatory but
25 "ref_clk_parent" is optional
28 - vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
29 - vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply
30 - vddp-ref-clk-supply : phandle to UFS device ref_clk pad power supply
31 - vddp-ref-clk-max-microamp : specifies max. load that can be drawn from this supply
32 - vddp-ref-clk-always-on : specifies if this supply needs to be kept always on
