Merge "dt-bindings: dcc: Add subnode for support multiple link-lists"

- qcom,save-reg: boolean, To save dcc registers state in memory after dcc

		 enable and disable

- link-list subnode: Each link-list subnode represents a link-list configured by default.

		     It supports configure multiple link-list nodes.

link-list subnode properties:

- qcom,data-sink: string, To specify default data sink for dcc, should be one

		  of the following:

		  "atb"	  : To send captured data over ATB to a trace sink

		clocks = <&clock_gcc clk_gcc_dcc_ahb_clk>;

		clock-names = "dcc_clk";

		qcom,save-reg;

		link_list_0 {

			qcom,curr-link-list = <2>;

			qcom,data-sink = "sram";

			qcom,link-list = <DCC_READ 0x1740300 6 0>,

					 <DCC_READ 0x1620500 4 0>,

					 <DCC_READ 0x7840000 1 0>,

					 <DCC_READ 0x7842000 16 0>,

					 <DCC_READ 0x7842500 2 0>;

		qcom,save-reg;

		};

		link_list_2 {

			qcom,curr-link-list = <3>;

			qcom,data-sink = "atb";

			qcom,link-list = <DCC_READ 0x18220d14 3 0>,
