Merge "Documentation: bindings: Add description for ICE instance"

                          	  property.

  - qcom,instance-type  	: describe the storage type for which ICE node is defined

			 	  currently, only "ufs" and "sdcc" are supported storage type

  - vdd-hba-supply		: regulated supply to be used by ICE HW

  - qcom,msm-bus,name		: bus for ICE transactions

  - qcom,msm-bus,num-cases	: bus case mapping for ICE HW

  - qcom,msm-bus,num-paths	: bus path mapping for iCE HW

  - qcom,msm-bus,vectors-KBps	: bus bandwidth to be voted

  - qcom,bus-vector-names	: bus vectors mapping

Example:

        ufs_ice: ufsice@630000 {

		qcom,instance-type = "ufs";

                status = "disabled";

        };

		compatible = "qcom,ice_card";

		reg = <0x1db0000 0x8000>;

		qcom,enable-ice-clk;

		clock-names = "ufs_core_clk", "bus_clk",

			      "iface_clk", "ice_core_clk";

		clocks = <&clock_gcc GCC_UFS_CARD_AXI_CLK>,

			 <&clock_gcc GCC_UFS_CARD_CLKREF_CLK>,

			 <&clock_gcc GCC_UFS_CARD_AHB_CLK>,

			 <&clock_gcc GCC_UFS_CARD_ICE_CORE_CLK>;

		qcom,op-freq-hz = <0>, <0>, <0>, <300000000>;

		vdd-hba-supply = <&ufs_card_gdsc>;

		qcom,msm-bus,name = "ufs_card_ice_noc";

		qcom,msm-bus,num-cases = <2>;

		qcom,msm-bus,vectors-KBps =

				<1 650 0 0>,    /* No vote */

				<1 650 1000 0>; /* Max. bandwidth */

		qcom,bus-vector-names = "MIN",

					"MAX";

		qcom,instance-type = "ufs_card";
