Subject: [PATCH v2 04/15] dt-bindings: ufs: drop unused/old ufs-qcom PHY bindings

The Qualcomm UFS PHY bindings are documented in
bindings/phy/qcom,qmp-phy.yaml and the compatibles from separate file
bindings/ufs/ufs-qcom.txt are not used at all.

-* Qualcomm Technologies Inc Universal Flash Storage (UFS) PHY
-
-UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
-Each UFS PHY node should have its own node.
-
-To bind UFS PHY with UFS host controller, the controller node should
-contain a phandle reference to UFS PHY node.
-
-Required properties:
-- compatible        : compatible list, contains one of the following -
-			"qcom,ufs-phy-qmp-20nm" for 20nm ufs phy,
-			"qcom,ufs-phy-qmp-14nm" for legacy 14nm ufs phy,
-			"qcom,msm8996-ufs-phy-qmp-14nm" for 14nm ufs phy
-			 present on MSM8996 chipset.
-- reg               : should contain PHY register address space (mandatory),
-- reg-names         : indicates various resources passed to driver (via reg proptery) by name.
-                      Required "reg-names" is "phy_mem".
-- #phy-cells        : This property shall be set to 0
-- vdda-phy-supply   : phandle to main PHY supply for analog domain
-- vdda-pll-supply   : phandle to PHY PLL and Power-Gen block power supply
-- clocks	    : List of phandle and clock specifier pairs
-- clock-names       : List of clock input name strings sorted in the same
-		      order as the clocks property. "ref_clk_src", "ref_clk",
-		      "tx_iface_clk" & "rx_iface_clk" are mandatory but
-		      "ref_clk_parent" is optional
-
-Optional properties:
-- vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
-- vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply
-- vddp-ref-clk-supply   : phandle to UFS device ref_clk pad power supply
-- vddp-ref-clk-max-microamp : specifies max. load that can be drawn from this supply
-- resets : specifies the PHY reset in the UFS controller
-
-Example:
-
-	ufsphy1: ufsphy@...97000 {
-		compatible = "qcom,ufs-phy-qmp-20nm";
-		reg = <0xfc597000 0x800>;
-		reg-names = "phy_mem";
-		#phy-cells = <0>;
-		vdda-phy-supply = <&pma8084_l4>;
-		vdda-pll-supply = <&pma8084_l12>;
-		vdda-phy-max-microamp = <50000>;
-		vdda-pll-max-microamp = <1000>;
-		clock-names = "ref_clk_src",
-			"ref_clk_parent",
-			"ref_clk",
-			"tx_iface_clk",
-			"rx_iface_clk";
-		clocks = <&clock_rpm clk_ln_bb_clk>,
-			<&clock_gcc clk_pcie_1_phy_ldo >,
-			<&clock_gcc clk_ufs_phy_ldo>,
-			<&clock_gcc clk_gcc_ufs_tx_cfg_clk>,
-			<&clock_gcc clk_gcc_ufs_rx_cfg_clk>;
-		resets = <&ufshc 0>;
-	};
-
-	ufshc: ufshc@...98000 {
-		#reset-cells = <1>;
-		...
-		phys = <&ufsphy1>;
-		phy-names = "ufsphy";
-	};
