From f7d933388f11f66e5af9e5663a17f26523fddd07 Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Fri, 23 Oct 2020 11:41:39 +0200 Subject: [PATCH] arm64: dts: meson: odroid-n2 plus: fix vddcpu_a pwm On the odroid N2 plus, cpufreq is not available due to an error on the cpu regulators. vddcpu a and b get the same PWM. The one provided to vddcpu A is incorrect. Because vddcpu B PWM is busy the regulator cannot register: > pwm-regulator regulator-vddcpu-b: Failed to get PWM: -16 Like on the odroid n2, use PWM A out of GPIOE_2 for vddcpu A to fix the problem Fixes: 98d24896ee11 ("arm64: dts: meson: add support for the ODROID-N2+") Signed-off-by: Jerome Brunet Acked-by: Neil Armstrong Signed-off-by: Kevin Hilman Link: https://lore.kernel.org/r/20201023094139.809379-1-jbrunet@baylibre.com --- arch/arm64/boot/dts/amlogic/meson-g12b-odroid-n2-plus.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/amlogic/meson-g12b-odroid-n2-plus.dts b/arch/arm64/boot/dts/amlogic/meson-g12b-odroid-n2-plus.dts index 5de2815..ce1198a 100644 --- a/arch/arm64/boot/dts/amlogic/meson-g12b-odroid-n2-plus.dts +++ b/arch/arm64/boot/dts/amlogic/meson-g12b-odroid-n2-plus.dts @@ -19,7 +19,7 @@ regulator-min-microvolt = <680000>; regulator-max-microvolt = <1040000>; - pwms = <&pwm_AO_cd 1 1500 0>; + pwms = <&pwm_ab 0 1500 0>; }; &vddcpu_b { -- 2.7.4
