It introduces the Qualcomm Shikra MDSS display subsystem support at the SoC level, and enables display on the Qualcomm Shikra CQS EVK and CQM EVK boards with the required DSI panel nodes. Dependencies: https://lore.kernel.org/all/20260929-wled-supply-series-v1-0-75d0a83b4b00@oss.qualcomm.com/ --- Changes in v5: - Drive the panel backlight from an external WLED driver whose enable input is wired to GPIO91, modeled as a fixed regulator (vreg_wled) (Dmitry) - Wire it up as the panel's wled-supply and drop the now-unused panel_bl_en/panel_bl_en_suspend pinctrl states(Dmitry) - Link to v4: https://lore.kernel.org/all/20260916-shikra-dt-changes-v4-0-d5d5c3ffe070@oss.qualcomm.com/ Changes in v4: - Rebased on top of next-20260915 tag. - Dropped all prerequisite-message-id references since the dependent patches have been merged. - Link to v3: https://lore.kernel.org/all/20260713-shikra-dt-changes-v3-0-15102fca9570@oss.qualcomm.com/ Changes in v3: - Drop redundant vph_pwr fixed-regulator node (Krzysztof Kozlowski) - Remove vin-supply = <&vph_pwr> from lcd_bias node (Krzysztof Kozlowski). - Add the new line between the last property and the following subnodes in mdss block(Konrad). - Link to v2: https://patch.msgid.link/20260706-shikra-dt-changes-v2-0-56fcd1659ea4@oss.qualcomm.com Changes in v2: - Replace QCM2290-specific RPM power domain identifiers with generic RPMPD_VDDCX/VDDMX macros in Shikra display and DSI nodes. - Add missing blank line before status = "okay" in &mdss_dsi0 node(Dmitry). - Split avdd-supply and avee-supply into separate regulators vreg_disp_p and vreg_disp_n instead of sharing the same lcd_bias regulator(Dmitry). - Sort tlmm pin state entries by pin number: gpio3, gpio86, gpio91, gpio151 (Dmitry). - Add vph_pwr as an always-on fixed regulator representing the main board power supply, used as vin-supply for lcd_bias. - Droped the 5th patch "Shikra LT9611UXD support". NAK by Dmitry. Once the hdmi-dsi driver is fixed then we will post DT changes. - Link to v1: https://patch.msgid.link/20260627-shikra-dt-changes-v1-0-449a402673d0@oss.qualcomm.com Signed-off-by: Arpit Saini Signed-off-by: Nabige Aala To: Bjorn Andersson To: Konrad Dybcio To: Rob Herring To: Krzysztof Kozlowski To: Conor Dooley To: Abel Vesa Cc: linux-arm-msm@vger.kernel.org Cc: devicetree@vger.kernel.org Cc: linux-kernel@vger.kernel.org Cc: arpit.saini@oss.qualcomm.com --- Arpit Saini (3): arm64: dts: qcom: shikra-cqs-evk: Enable display and add ili7807s panel arm64: dts: qcom: shikra-cqm-evk: Enable display and add ili7807s panel arm64: defconfig: Enable ILI7807S DSI panel driver Nabige Aala (1): arm64: dts: qcom: shikra: Add MDSS display subsystem arch/arm64/boot/dts/qcom/shikra-cqm-evk.dts | 110 +++++++++++++++ arch/arm64/boot/dts/qcom/shikra-cqs-evk.dts | 110 +++++++++++++++ arch/arm64/boot/dts/qcom/shikra.dtsi | 206 +++++++++++++++++++++++++++- arch/arm64/configs/defconfig | 1 + 4 files changed, 425 insertions(+), 2 deletions(-) --- base-commit: 6474fa070f2b8013b4b87350b775b8c3be6e8aac change-id: 20260626-shikra-dt-changes-8d127be951d5 Best regards, -- Nabige Aala
