This series adds support for several popular Amlogic S905X3 (SM1) Android Set-Top Box devices. Like most Android box devices, they ship in variants with multiple RAM, eMMC, WiFi and BT configurations. RAM and eMMC are not something we need to consider to get a working boot, but we do need to get the correct connectivity spec. Broadly speaking we see boxes with Higher and Lower spec connectivity; High spec is Gigabit Ethernet and Faster dual antennna WiFi, and Lower spec is Megabit Ethernet and a single antenna. In some low-end boxes BT is omitted. As initial distro setup is frequently performed over SSH or an HDMI GUI app it is important for users to pick a device-tree with the correct Ethernet PHY spec else connectivity is impossible. To aid this we append a -gbit suffix to X96-AIR and A95XF3-AIR models using an external Gigabit PHY, while 10/00 models with internal PHY have no suffix. NB: At the current time the Realtek 8822CS and MT7668 WiFi/BT modules we have seen on 'AIR' devices are not supported in the kernel so these are deliberately omitted. The H96-Max uses a conventional Broadcom module so has more complete support. For now the boxes have simple HDMI audio support; wiring up the Headphone socket will be done at a later date. Changes since RFC(v1) series: - Add Robs binding acks on patches 4/7/8 (patches 2/5 still need acks) - Rename and rework patches around -gbit (as requested by Neil) - Correct 'manufacturer' typo on patch 8 - Rebase against v5.18/dt64 branch Christian Hewitt (9): arm64: dts: meson: add common SM1 ac2xx dtsi dt-bindings: arm: amlogic: add X96-AIR bindings arm64: dts: meson: add initial device-trees for X96-AIR dt-bindings: vendor-prefixes: add cyx prefix dt-bindings: arm: amlogic: add A95XF3-AIR bindings arm64: dts: meson: add initial device-trees for A95XF3-AIR dt-bindings: vendor-prefixes: add haochuangyi prefix dt-bindings: arm: amlogic: add H96-Max bindings arm64: dts: meson: add initial device-tree for H96-Max .../devicetree/bindings/arm/amlogic.yaml | 5 + .../devicetree/bindings/vendor-prefixes.yaml | 4 + arch/arm64/boot/dts/amlogic/Makefile | 5 + .../dts/amlogic/meson-sm1-a95xf3-air-gbit.dts | 129 ++++++++ .../boot/dts/amlogic/meson-sm1-a95xf3-air.dts | 108 +++++++ .../boot/dts/amlogic/meson-sm1-ac2xx.dtsi | 300 ++++++++++++++++++ .../boot/dts/amlogic/meson-sm1-h96-max.dts | 145 +++++++++ .../dts/amlogic/meson-sm1-x96-air-gbit.dts | 133 ++++++++ .../boot/dts/amlogic/meson-sm1-x96-air.dts | 112 +++++++ 9 files changed, 941 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-a95xf3-air-gbit.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-a95xf3-air.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-ac2xx.dtsi create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-h96-max.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-x96-air-gbit.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-x96-air.dts -- 2.17.1
