The actual regulator switch is done by the patch 'arm64: dts: qcom: sc7180-trogdor: Make pp3300_a the default supply for pp3300_hub', since it affects the entire trogdor platform. Here we only add the .dts files for lazor rev2 and replace the generic compatible entries in the rev1 .dts files.

The 'pp3300_a' path includes a load switch that can be controlled through GPIO84. Initially trogdor boards used 'pp3300_l7c' to power the USB hub, newer revisions (will) use 'pp3300_a' as supply for 'pp3300_hub'. Add a DT node for the 'pp3300_a' path and a pinctrl entry for the GPIO. Make this path the default and keep trogdor rev1, lazor rev0 and rev1 on 'pp3300_l7c'. These earlier revisions also allocated the GPIO to the purpose of controlling the power switch, so there is no need to limit the pinctrl config to newer revisions. Remove the platform-wide 'always-on' property from 'pp3300_l7c' and add it to the boards that use this supply. Also delete the 'always-on' of 'pp3300_hub' for these boards. Signed-off-by: Matthias Kaehlcke --- Changes in v2: - added 'always-on' and 'boot-on' properties for new 'pp3300_hub' - removed platform-wide 'always-on' property for 'pp3300_l7c' - added 'always-on' property to 'pp3300_l7c' for boards that still use 'pp3300_l7c' - delete 'always-on' property of 'pp3300_hub' for boards that still use 'pp3300_l7c' - got rid of 'pp3300_hub_7c' label, just use 'pp3300_l7c' - fixed position of 'en_pp3300_hub' node to respect ordering - updated commit message .../boot/dts/qcom/sc7180-trogdor-lazor-r0.dts | 13 ++++++++ .../boot/dts/qcom/sc7180-trogdor-lazor-r1.dts | 13 ++++++++ .../arm64/boot/dts/qcom/sc7180-trogdor-r1.dts | 13 ++++++++ arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi | 33 ++++++++++++++++++- 4 files changed, 71 insertions(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r0.dts b/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r0.dts index ae4c23a4fe65..1d809269e7ef 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r0.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r0.dts @@ -14,6 +14,15 @@ / { compatible = "google,lazor-rev0", "qcom,sc7180"; }; +&pp3300_hub { + /* pp3300_l7c is used to power the USB hub */ + /delete-property/regulator-always-on; +}; + +&pp3300_l7c { + regulator-always-on; +}; + &sn65dsi86_out { /* * Lane 0 was incorrectly mapped on the cable, but we've now decided @@ -22,3 +31,7 @@ &sn65dsi86_out { */ lane-polarities = <1 0>; }; + +&usb_hub { + vdd-supply = <&pp3300_l7c>; +}; diff --git a/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r1.dts b/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r1.dts index f6ee1beba458..1d573523d6b6 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r1.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-trogdor-lazor-r1.dts @@ -13,3 +13,16 @@ / { model = "Google Lazor (rev1)"; compatible = "google,lazor-rev1", "qcom,sc7180"; }; + +&pp3300_hub { + /* pp3300_l7c is used to power the USB hub */ + /delete-property/regulator-always-on; +}; + +&pp3300_l7c { + regulator-always-on; +}; + +&usb_hub { + vdd-supply = <&pp3300_l7c>; +}; diff --git a/arch/arm64/boot/dts/qcom/sc7180-trogdor-r1.dts b/arch/arm64/boot/dts/qcom/sc7180-trogdor-r1.dts index 0a281c24841c..6603f2102233 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-trogdor-r1.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-trogdor-r1.dts @@ -58,10 +58,23 @@ ap_ts: touchscreen@10 { }; }; +&pp3300_hub { + /* pp3300_l7c is used to power the USB hub */ + /delete-property/regulator-always-on; +}; + +&pp3300_l7c { + regulator-always-on; +}; + &sdhc_2 { status = "okay"; }; +&usb_hub { + vdd-supply = <&pp3300_l7c>; +}; + /* PINCTRL - board-specific pinctrl */ &tlmm { diff --git a/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi b/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi index bf875589d364..50e733412a7f 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi @@ -174,6 +174,25 @@ pp3300_fp_tp: pp3300-fp-tp-regulator { vin-supply = <&pp3300_a>; }; + pp3300_hub: pp3300-hub { + compatible = "regulator-fixed"; + regulator-name = "pp3300_hub"; + + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + + gpio = <&tlmm 84 GPIO_ACTIVE_HIGH>; + enable-active-high; + pinctrl-names = "default"; + pinctrl-0 = <&en_pp3300_hub>; + + /* AP turns on with en_pp3300_hub; always on for AP */ + regulator-always-on; + regulator-boot-on; + + vin-supply = <&pp3300_a>; + }; + /* BOARD-SPECIFIC TOP LEVEL NODES */ backlight: backlight { @@ -469,7 +488,6 @@ ppvar_l6c: ldo6 { regulator-initial-mode = ; }; - pp3300_hub: pp3300_l7c: ldo7 { regulator-min-microvolt = <3304000>; regulator-max-microvolt = <3304000>; @@ -1164,6 +1182,19 @@ pinconf { }; }; + en_pp3300_hub: en-pp3300-hub { + pinmux { + pins = "gpio84"; + function = "gpio"; + }; + + pinconf { + pins = "gpio84"; + drive-strength = <2>; + bias-disable; + }; + }; + fpmcu_boot0: fpmcu-boot0 { pinmux { pins = "gpio10";
