Also adds OF_DEV_AUXDATA for EHRPWM & ECAP driver to use EHRPWM & ECAP clock. Signed-off-by: Philip Avinash --- Changes since v4: - Add pin mux for PWM devices ECAP & EHRPWM. Changes since v3: - add pin mux info for EHRPWM1. Changes since v1: - Reusing ti,am33xx as compatible field as both IP's are similar with am33xx platform and da850 has no platform specific dependency. arch/arm/boot/dts/da850.dtsi | 73 ++++++++++++++++++++++++++++++++++++++ arch/arm/mach-davinci/da8xx-dt.c | 5 +++ 2 files changed, 78 insertions(+) diff --git a/arch/arm/boot/dts/da850.dtsi b/arch/arm/boot/dts/da850.dtsi index 3ade343..b2ae730 100644 --- a/arch/arm/boot/dts/da850.dtsi +++ b/arch/arm/boot/dts/da850.dtsi @@ -71,6 +71,49 @@ 0x28 0x00222222 0x00ffffff >; }; + ehrpwm0a_pins: pinmux_ehrpwm0a_pins { + pinctrl-single,bits = < + /* EPWM0A */ + 0xc 0x00000002 0x0000000f + >; + }; + ehrpwm0b_pins: pinmux_ehrpwm0b_pins { + pinctrl-single,bits = < + /* EPWM0B */ + 0xc 0x00000020 0x000000f0 + >; + }; + ehrpwm1a_pins: pinmux_ehrpwm1a_pins { + pinctrl-single,bits = < + /* EPWM1A */ + 0x14 0x00000002 0x0000000f + >; + }; + ehrpwm1b_pins: pinmux_ehrpwm1b_pins { + pinctrl-single,bits = < + /* EPWM1B */ + 0x14 0x00000020 0x000000f0 + >; + }; + ecap0_pins: pinmux_ecap0_pins { + pinctrl-single,bits = < + /* ECAP0_APWM0 */ + 0x8 0x20000000 0xf0000000 + >; + }; + ecap1_pins: pinmux_ecap1_pins { + pinctrl-single,bits = < + /* ECAP1_APWM1 */ + 0x4 0x40000000 0xf0000000 + >; + }; + ecap2_pins: pinmux_ecap2_pins { + pinctrl-single,bits = < + /* ECAP2_APWM2 */ + 0x4 0x00000004 0x0000000f + >; + }; + }; serial0: serial@1c42000 { compatible = "ns16550a"; @@ -122,6 +165,36 @@ interrupts = <16>; status = "disabled"; }; + ehrpwm0: ehrpwm@01f00000 { + compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm"; + #pwm-cells = <3>; + reg = <0x300000 0x2000>; + status = "disabled"; + }; + ehrpwm1: ehrpwm@01f02000 { + compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm"; + #pwm-cells = <3>; + reg = <0x302000 0x2000>; + status = "disabled"; + }; + ecap0: ecap@01f06000 { + compatible = "ti,da850-ecap", "ti,am33xx-ecap"; + #pwm-cells = <3>; + reg = <0x306000 0x80>; + status = "disabled"; + }; + ecap1: ecap@01f07000 { + compatible = "ti,da850-ecap", "ti,am33xx-ecap"; + #pwm-cells = <3>; + reg = <0x307000 0x80>; + status = "disabled"; + }; + ecap2: ecap@01f08000 { + compatible = "ti,da850-ecap", "ti,am33xx-ecap"; + #pwm-cells = <3>; + reg = <0x308000 0x80>; + status = "disabled"; + }; }; nand_cs3@62000000 { compatible = "ti,davinci-nand"; diff --git a/arch/arm/mach-davinci/da8xx-dt.c b/arch/arm/mach-davinci/da8xx-dt.c index d83de8f..05bb9a2 100644 --- a/arch/arm/mach-davinci/da8xx-dt.c +++ b/arch/arm/mach-davinci/da8xx-dt.c @@ -41,6 +41,11 @@ struct of_dev_auxdata da850_auxdata_lookup[] __initdata = { OF_DEV_AUXDATA("ti,davinci-i2c", 0x01c22000, "i2c_davinci.1", NULL), OF_DEV_AUXDATA("ti,davinci-wdt", 0x01c21000, "watchdog", NULL), OF_DEV_AUXDATA("ti,da830-mmc", 0x01c40000, "da830-mmc.0", NULL), + OF_DEV_AUXDATA("ti,da850-ehrpwm", 0x01f00000, "ehrpwm", NULL), + OF_DEV_AUXDATA("ti,da850-ehrpwm", 0x01f02000, "ehrpwm", NULL), + OF_DEV_AUXDATA("ti,da850-ecap", 0x01f06000, "ecap", NULL), + OF_DEV_AUXDATA("ti,da850-ecap", 0x01f07000, "ecap", NULL), + OF_DEV_AUXDATA("ti,da850-ecap", 0x01f08000, "ecap", NULL), {} }; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
