Enable the main RGB sensor on the Lenovo x13s a five megapixel 2 lane DPHY MIPI sensor connected to cisphy0. With the pm8008 patches recently applied to the x13s dtsi we can now also enable the RGB sensor. Once done we have all upstream support necessary for the RGB sensor on x13s. Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx> --- The Lenovo x13s has a five megapixel ov5675 sensor as well as a one megpixel ov9734 B+W NOIR sensor for low-light face detection login. This patch enables the RGB sensor. A gpio exists in the upstream dts to indicate camera activity which currently we don't tie to CAMSS activity yet. Running - A Linux distro which ships libcamera > 0.3.0 - Firefox nightly - Setting Firefox about:config:media.webrtc.capture.allow-pipewire = true It should then be possible to use the on-board MIPI camera for Zoom, Hangouts etc. Changes in v2: - Drops useless assigned-clocks entry - Link to v1: https://lore.kernel.org/r/20240801-b4-linux-next-24-07-31-camss-sc8280xp-lenovo-rgb-v2-v1-1-30622c6a0c48@xxxxxxxxxx --- .../dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts | 72 ++++++++++++++++++++++ 1 file changed, 72 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 a7c5a3f5926c7..2bdfff2a16cad 100644 --- a/arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts +++ b/arch/arm64/boot/dts/qcom/sc8280xp-lenovo-thinkpad-x13s.dts @@ -592,6 +592,62 @@ vreg_l10d: ldo10 { }; }; +&camcc { + status = "okay"; +}; + +&camss { + vdda-phy-supply = <&vreg_l6d>; + vdda-pll-supply = <&vreg_l4d>; + + status = "okay"; + + ports { + /* The port index denotes CSIPHY id i.e. csiphy0 */ + port@0 { + csiphy0_lanes01_ep: endpoint@0 { + reg = <0>; + clock-lanes = <7>; + data-lanes = <0 1>; + remote-endpoint = <&ov5675_ep>; + }; + }; + }; +}; + +&cci2 { + status = "okay"; +}; + +&cci2_i2c1 { + camera@10 { + compatible = "ovti,ov5675"; + reg = <0x10>; + + reset-gpios = <&tlmm 15 GPIO_ACTIVE_LOW>; + pinctrl-names = "default"; + pinctrl-0 = <&cam_rgb_default>; + + clocks = <&camcc CAMCC_MCLK3_CLK>; + + orientation = <0>; /* Front facing */ + + avdd-supply = <&vreg_l6q>; + dvdd-supply = <&vreg_l2q>; + dovdd-supply = <&vreg_l7q>; + + port { + ov5675_ep: endpoint { + clock-lanes = <0>; + data-lanes = <1 2>; + link-frequencies = /bits/ 64 <450000000>; + remote-endpoint = <&csiphy0_lanes01_ep>; + }; + }; + + }; +}; + &dispcc0 { status = "okay"; }; @@ -1436,6 +1492,22 @@ cam_indicator_en: cam-indicator-en-state { bias-disable; }; + cam_rgb_default: cam-rgb-default-state { + mclk-pins { + pins = "gpio17"; + function = "cam_mclk"; + drive-strength = <16>; + bias-disable; + }; + + sc-rgb-xshut-n-pins { + pins = "gpio15"; + function = "gpio"; + drive-strength = <2>; + bias-disable; + }; + }; + edp_reg_en: edp-reg-en-state { pins = "gpio25"; function = "gpio"; --- base-commit: cd19ac2f903276b820f5d0d89de0c896c27036ed change-id: 20240731-b4-linux-next-24-07-31-camss-sc8280xp-lenovo-rgb-v2-525b250dfb84 Best regards, -- Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx>
