The phyboard-izar kit comes with a 10.1" lvds display with usb touch as addon. dsi1 is routed to the carrier board onto a connector. To use that Phytec has developed a small extension board "PEB-AV-15" with a Lontium LT8912B dsi->hdmi bridge. Changes for v2: - Drop the following patch as it got merged in the last window: dt-bindings: display: bridge: lt8912b: Drop reset gpio requirement - In arm64: dts: ti: k3-am68-phyboard-izar: Add LVDS-Display Reduce pwm frequency to ~23kHz for the backlight. This is supported by the backlight and works better with most fans. Since the fan connector is using PWM0_A and the backlight PWM0_B they need to use the same frequency. - In arm64: dts: ti: k3-am68-phyboard-izar: Add PEB-AV-15 overlay Fix license in boilerplate: s/GPL-2.0-or-only or MIT/GPL-2.0-only OR MIT Link to v1: https://lore.kernel.org/linux-devicetree/20260130205820.83189-1-d.haller@phytec.de/ Dominik Haller (5): arm64: dts: ti: k3-am68-phyboard-izar: Assign dss clocks arm64: dts: ti: k3-am68-phycore-som: Add DSI->LVDS bridge arm64: dts: ti: k3-am68-phyboard-izar: Add LVDS-Display arm64: dts: ti: k3-j721s2-main: Add DSI1 arm64: dts: ti: k3-am68-phyboard-izar: Add PEB-AV-15 overlay arch/arm64/boot/dts/ti/Makefile | 8 + ...-am68-phyboard-izar-lvds-ph128800t006.dtso | 125 ++++++++++++ .../ti/k3-am68-phyboard-izar-peb-av-15.dtso | 192 ++++++++++++++++++ .../boot/dts/ti/k3-am68-phyboard-izar.dts | 18 ++ .../boot/dts/ti/k3-am68-phycore-som.dtsi | 17 ++ arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi | 39 ++++ 6 files changed, 399 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-am68-phyboard-izar-lvds-ph128800t006.dtso create mode 100644 arch/arm64/boot/dts/ti/k3-am68-phyboard-izar-peb-av-15.dtso -- 2.43.0
