This patch series aims to add initial support for the Xiaomi Mi TV Stick. Xiaomi Mi TV Stick is a small Amlogic-based Android TV stick released in 2020, and known as `xiaomi-aquaman` internally (in the downstream kernel, u-boot, ...) Its specifications are as follows: * Amlogic S805Y SoC (believed to be mostly identical to S805X) * 8 GB eMMC * 1 GB of RAM * Android TV 9, upgradable to Android TV 10 There are multiple variants: * 1. Green PCB, manufactured in 2020, known UART pinout (helpfully labeled on the board) * 2. Blue PCB, not much documentation about it, presumably manufactured between 2021 and 2023 * 3. Green PCB, manufactured in 2023, known UART pinout, some layout changes compared to the 2020 variant Among these variants, there are many boards using multiple different Wi-Fi chips. Supporting all of them is out of scope for this patch series. As of the time of writing this has only been tested on the 3rd variant. It is believed that software-wise all three work mostly the same (if we don't count Wi-Fi), but testing on the other variants would still be appreciated. The devicetree is based on the Amlogic P241 DTS. Changes since v1 [1]: * remove useless nodes: cvbs-connector, ethmac, internal_phy, ir * add `amlogic,s805y` DT binding section * add S805Y dtsi: meson-gxl-s805y.dtsi * adjust DT `model` to "Xiaomi Mi TV Stick (Aquaman)" * explain the changes being done a bit more in the commit message for the DT patch * drop `clocks` and `clock-names` from pwm_ef (background: [2]) * change sound `model` to "XIAOMI-AQUAMAN" [1]: https://lore.kernel.org/all/20250131200319.19996-1-funderscore@xxxxxxxxxxxxxxxx/ [2]: https://lore.kernel.org/linux-amlogic/20241227212514.1376682-1-martin.blumenstingl@xxxxxxxxxxxxxx/ Ferass El Hafidi (2): dt-bindings: arm: amlogic: add S805Y and Mi TV Stick arm64: dts: amlogic: add support for xiaomi-aquaman/Mi TV Stick .../devicetree/bindings/arm/amlogic.yaml | 7 + arch/arm64/boot/dts/amlogic/Makefile | 1 + .../meson-gxl-s805y-xiaomi-aquaman.dts | 288 ++++++++++++++++++ .../boot/dts/amlogic/meson-gxl-s805y.dtsi | 10 + 4 files changed, 306 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-gxl-s805y-xiaomi-aquaman.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-gxl-s805y.dtsi -- 2.47.1
