From: Hui Liu <quic_huliu@xxxxxxxxxxx> The Volume Down & Power buttons are controlled by the PMIC via the PON hardware, and the Volume Up is connected to a PMIC gpio. Enable the necessary hardware and setup the GPIO state for the Volume Up gpio key. Signed-off-by: Hui Liu <quic_huliu@xxxxxxxxxxx> --- Changes in v4: - Switch the order of "pinctrl-0" and "pinctrl-names". - Update "volume_up" to "Volume_up". - Remove "linux,input-type", because the default value is 1(EV_KEY). - Link to v3: https://lore.kernel.org/r/20240301-gpio-keys-v3-1-ca664de8775c@xxxxxxxxxxx Changes in v3: - Update the commit more concise and explicit. - remove "power-source" property and update the numeric value to defined name for "qcom,drive-strength". - Link to v2: https://lore.kernel.org/r/20240223-gpio-keys-v2-1-19f48b3d8762@xxxxxxxxxxx Changes in v2: - Update the commit description. - Link to v1: https://lore.kernel.org/r/20240206-gpio-keys-v1-1-7683799daf8d@xxxxxxxxxxx --- arch/arm64/boot/dts/qcom/qcm6490-idp.dts | 41 ++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/qcm6490-idp.dts b/arch/arm64/boot/dts/qcom/qcm6490-idp.dts index acf145d1d97c..12e162613ed0 100644 --- a/arch/arm64/boot/dts/qcom/qcm6490-idp.dts +++ b/arch/arm64/boot/dts/qcom/qcm6490-idp.dts @@ -9,7 +9,9 @@ #define PM7250B_SID 8 #define PM7250B_SID1 9 +#include <dt-bindings/input/linux-event-codes.h> #include <dt-bindings/leds/common.h> +#include <dt-bindings/pinctrl/qcom,pmic-gpio.h> #include <dt-bindings/regulator/qcom,rpmh-regulator.h> #include "sc7280.dtsi" #include "pm7250b.dtsi" @@ -39,6 +41,22 @@ chosen { stdout-path = "serial0:115200n8"; }; + gpio-keys { + compatible = "gpio-keys"; + + pinctrl-0 = <&key_vol_up_default>; + pinctrl-names = "default"; + + key-volume-up { + label = "Volume_up"; + gpios = <&pm7325_gpios 6 GPIO_ACTIVE_LOW>; + linux,code = <KEY_VOLUMEUP>; + wakeup-source; + debounce-interval = <15>; + linux,can-disable; + }; + }; + reserved-memory { xbl_mem: xbl@80700000 { reg = <0x0 0x80700000 0x0 0x100000>; @@ -421,6 +439,16 @@ vreg_bob_3p296: bob { }; }; +&pm7325_gpios { + key_vol_up_default: key-vol-up-state { + pins = "gpio6"; + function = "normal"; + input-enable; + bias-pull-up; + qcom,drive-strength = <PMIC_GPIO_STRENGTH_LOW>; + }; +}; + &pm8350c_pwm { status = "okay"; @@ -448,6 +476,19 @@ led@3 { }; }; +&pmk8350_pon { + status = "okay"; +}; + +&pon_pwrkey { + status = "okay"; +}; + +&pon_resin { + linux,code = <KEY_VOLUMEDOWN>; + status = "okay"; +}; + &qupv3_id_0 { status = "okay"; }; --- base-commit: 23e11d0318521e8693459b0e4d23aec614b3b68b change-id: 20240206-gpio-keys-138bbd850298 Best regards, -- Hui Liu <quic_huliu@xxxxxxxxxxx>
