Subject[PATCH] counter: ti-eqep: Enable for TDA4VM/J721E
Date
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>;
};
};
