[PATCH] counter: ti-eqep: Enable for TDA4VM/J721E

[Jason Kridner <jkridner@beagleboard.org>]

Counter TI-EQEP was tested on TDA4VM/J721E SoC.

Overlay used for testing EQEP0 and EQEP1:

    &cbass_main {
	#address-cells = <2>;
	#size-cells = <2>;

	eqep0: qep@3200000 {
		compatible = "ti,am3352-eqep";
		reg = <0 0x3200000 0 0x100>;
		power-domains = <&k3_pds 94 TI_SCI_PD_EXCLUSIVE>;
		clocks = <&k3_clks 94 0>;
		clock-names = "eqep0-ficlk";
		interrupts = <GIC_SPI 322 IRQ_TYPE_EDGE_RISING>;
		interrupt-names = "eqep0";
		symlink = "bone/eQEP0"; /* A - P9_42, B - P9_27 */

		count_mode = <0>;
		swap_input = <0>;
		invert_qa = <1>;
		invert_qb = <1>;
		invert_qi = <0>;
		invert_qs = <0>;
	};

	eqep1: qep@3210000 {
		compatible = "ti,am3352-eqep";
		reg = <0 0x3210000 0 0x100>;
		power-domains = <&k3_pds 95 TI_SCI_PD_EXCLUSIVE>;
		clocks = <&k3_clks 95 0>;
		clock-names = "eqep1-ficlk";
		interrupts = <GIC_SPI 323 IRQ_TYPE_EDGE_RISING>;
		interrupt-names = "eqep1";
		symlink = "bone/eQEP1"; /* A - P8_35, B - P8_33 */

		count_mode = <0>;
		swap_input = <0>;
		invert_qa = <1>;
		invert_qb = <1>;
		invert_qi = <0>;
		invert_qs = <0>;
	};

	eqep2: qep@3220000 {
		status = "disabled";
		compatible = "ti,am3352-eqep";
		reg = <0 0x3220000 0 0x100>;
		power-domains = <&k3_pds 96 TI_SCI_PD_EXCLUSIVE>;
		clocks = <&k3_clks 96 0>;
		clock-names = "eqep2-ficlk";
		interrupts = <GIC_SPI 324 IRQ_TYPE_EDGE_RISING>;
		interrupt-names = "eqep2";

		count_mode = <0>;
		swap_input = <0>;
		invert_qa = <1>;
		invert_qb = <1>;
		invert_qi = <0>;
		invert_qs = <0>;
	};
    };
