Signed-off-by: Steev Klimaszewski Reviewed-by: Bjorn Andersson --- Changes since v6: * Remove allowed-modes as they aren't needed * Remove regulator-allow-set-load * Set regulator-always-on because the wifi chip also uses the regulator * cts pin uses bias-bus-hold * Alphabetize uart2 pins Changes since v5: * Update patch subject * Specify initial mode (via guess) for vreg_s1c * Drop uart17 definition * Rename bt_en to bt_default because configuring more than one pin * Correct (maybe) bias configurations * Correct cts gpio * Split rts-tx into two nodes * Drop incorrect link in the commit message Changes since v4: * Address Konrad's review comments. Changes since v3: * Add vreg_s1c * Add regulators and not dead code * Fix commit message changelog Changes since v2: * Remove dead code and add TODO comment * Make dtbs_check happy with the pin definitions .../qcom/sc8280xp-lenovo-thinkpad-x13s.dts | 78 +++++++++++++++++++ 1 file changed, 78 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts b/arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts index 92d365519546..05e66505e5cc 100644 --- a/arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts +++ b/arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts @@ -24,6 +24,7 @@ / { aliases { i2c4 = &i2c4; i2c21 = &i2c21; + serial1 = &uart2; }; wcd938x: audio-codec { @@ -431,6 +432,14 @@ regulators-1 { qcom,pmic-id = "c"; vdd-bob-supply = <&vreg_vph_pwr>; + vreg_s1c: smps1 { + regulator-name = "vreg_s1c"; + regulator-min-microvolt = <1880000>; + regulator-max-microvolt = <1900000>; + regulator-initial-mode = ; + regulator-always-on; + }; + vreg_l1c: ldo1 { regulator-name = "vreg_l1c"; regulator-min-microvolt = <1800000>; @@ -918,6 +927,32 @@ &qup0 { status = "okay"; }; +&uart2 { + pinctrl-0 = <&uart2_default>; + pinctrl-names = "default"; + + status = "okay"; + + bluetooth { + compatible = "qcom,wcn6855-bt"; + + vddio-supply = <&vreg_s10b>; + vddbtcxmx-supply = <&vreg_s12b>; + vddrfacmn-supply = <&vreg_s12b>; + vddrfa0p8-supply = <&vreg_s12b>; + vddrfa1p2-supply = <&vreg_s11b>; + vddrfa1p7-supply = <&vreg_s1c>; + + max-speed = <3200000>; + + enable-gpios = <&tlmm 133 GPIO_ACTIVE_HIGH>; + swctrl-gpios = <&tlmm 132 GPIO_ACTIVE_HIGH>; + + pinctrl-0 = <&bt_default>; + pinctrl-names = "default"; + }; +}; + &qup1 { status = "okay"; }; @@ -1192,6 +1227,21 @@ hastings_reg_en: hastings-reg-en-state { &tlmm { gpio-reserved-ranges = <70 2>, <74 6>, <83 4>, <125 2>, <128 2>, <154 7>; + bt_default: bt-default-state { + hstp-sw-ctrl-pins { + pins = "gpio132"; + function = "gpio"; + bias-pull-down; + }; + + hstp-bt-en-pins { + pins = "gpio133"; + function = "gpio"; + drive-strength = <16>; + bias-disable; + }; + }; + edp_reg_en: edp-reg-en-state { pins = "gpio25"; function = "gpio"; @@ -1213,6 +1263,34 @@ i2c4_default: i2c4-default-state { bias-disable; }; + uart2_default: uart2-default-state { + cts-pins { + pins = "gpio121"; + function = "qup2"; + bias-bus-hold; + }; + + rts-pins { + pins = "gpio122"; + function = "qup2"; + drive-strength = <2>; + bias-disable; + }; + + rx-pins { + pins = "gpio124"; + function = "qup2"; + bias-pull-up; + }; + + tx-pins { + pins = "gpio123"; + function = "qup2"; + drive-strength = <2>; + bias-disable; + }; + }; + i2c21_default: i2c21-default-state { pins = "gpio81", "gpio82"; function = "qup21";
