From: Ivan Belokobylskiy <belokobylskij@xxxxxxxxx> Add initial support for LG Nexus 4 (mako). Features currently working: regulators, eMMC, and volume keys. Signed-off-by: Ivan Belokobylskiy <belokobylskij@xxxxxxxxx> Co-developed-by: David Heidelberg <david@xxxxxxx> Signed-off-by: David Heidelberg <david@xxxxxxx> --- Changes in v4: - Sorted regulators and added regulators compatible. - Corrected pmic include and references. - Moved &rpm outside of / node. - Moved and simplify pm8921 keypad. - Added chasis-type. - Dropped incomplete WiFi node, will be provided in future contributions. - Link to v3: https://lore.kernel.org/r/20250309-lg-nexus4-mako-v3-1-1dc2807df296@xxxxxxx Changes in v3: - rebased against next-20250307 - dropped backlight until driver gets converted to DT Changes in v2: - lge vendor doesn't exist anymore, rename to lg - sdcc@ to mmc@ to comply with dt-schema --- arch/arm/boot/dts/qcom/Makefile | 1 + .../boot/dts/qcom/qcom-apq8064-lg-nexus4-mako.dts | 344 +++++++++++++++++++++ 2 files changed, 345 insertions(+) diff --git a/arch/arm/boot/dts/qcom/Makefile b/arch/arm/boot/dts/qcom/Makefile index f06c6d425e91dd73c2b453d15543d95bd32383b9..0c1d116f6e84f76994aa8c8286350bdcd1657a42 100644 --- a/arch/arm/boot/dts/qcom/Makefile +++ b/arch/arm/boot/dts/qcom/Makefile @@ -12,6 +12,7 @@ dtb-$(CONFIG_ARCH_QCOM) += \ qcom-apq8064-ifc6410.dtb \ qcom-apq8064-sony-xperia-lagan-yuga.dtb \ qcom-apq8064-asus-nexus7-flo.dtb \ + qcom-apq8064-lg-nexus4-mako.dtb \ qcom-apq8074-dragonboard.dtb \ qcom-apq8084-ifc6540.dtb \ qcom-apq8084-mtp.dtb \ diff --git a/arch/arm/boot/dts/qcom/qcom-apq8064-lg-nexus4-mako.dts b/arch/arm/boot/dts/qcom/qcom-apq8064-lg-nexus4-mako.dts new file mode 100644 index 0000000000000000000000000000000000000000..51edd661e4bd903a32445d15955585a194574f30 --- /dev/null +++ b/arch/arm/boot/dts/qcom/qcom-apq8064-lg-nexus4-mako.dts @@ -0,0 +1,344 @@ +// SPDX-License-Identifier: GPL-2.0-only +#include <dt-bindings/gpio/gpio.h> +#include <dt-bindings/input/input.h> +#include <dt-bindings/mfd/qcom-rpm.h> +#include <dt-bindings/pinctrl/qcom,pmic-gpio.h> + +#include "qcom-apq8064-v2.0.dtsi" +#include "pm8821.dtsi" +#include "pm8921.dtsi" + +/ { + model = "LG Nexus 4 (mako)";
