Hi list, This series adds support for 2 new revisions of Radxa's ROCK Pi 4, namely ROCK Pi 4A+ and ROCK Pi 4B+. While most things are in common with the previous 4A and 4B revisions, they have OP1 revision of the SoC and eMMC soldered on board. Patch 4 and 5 add SPDIF and anlog Codec to the common device tree, since they are in place in previous revisions as well. It superseeds https://lore.kernel.org/linux-rockchip/d4e4e06e-6ddd-4707-232d-b829c1d646e6@xxxxxxxxx/ There is no example (which I could find) for Rockchip on how to deal with "+" revisions - so I looked up other SoCs and the rule seems to be to use the "+" for the model name (which is the "offical" name), but use "-plus" for compatible name and device tree files names (see "Raspberry Pi Model A+", for instance). A short node for testing ES8316 codec: The driver disables the headphone jack by default - for testing one would have to enable it via amixer with: amixer [card index] 'Right Headphone Mixer Right DAC' on amixer [card index] 'Left Headphone Mixer Left DAC' on Alex Changes in v2: - added additional compatibles for the new revisions (Heiko) - renamed ES8316 audio card name to "Analog" (Johan) - added patch for SPDIF - aligned spelling of board name(s) Alex Bee (5): dt-bindings: Add doc for ROCK Pi 4 A+ and B+ arm64: dts: rockchip: Add RK3399 ROCK Pi 4A+ board arm64: dts: rockchip: Add RK3399 ROCK Pi 4B+ board arm64: dts: rockchip: add ES8316 codec for ROCK Pi 4 arm64: dts: rockchip: add SPDIF node for ROCK Pi 4 .../devicetree/bindings/arm/rockchip.yaml | 4 +- arch/arm64/boot/dts/rockchip/Makefile | 2 + .../boot/dts/rockchip/rk3399-rock-pi-4.dtsi | 54 +++++++++++++++++++ .../dts/rockchip/rk3399-rock-pi-4a-plus.dts | 14 +++++ .../dts/rockchip/rk3399-rock-pi-4b-plus.dts | 47 ++++++++++++++++ 5 files changed, 120 insertions(+), 1 deletion(-) create mode 100644 arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4a-plus.dts create mode 100644 arch/arm64/boot/dts/rockchip/rk3399-rock-pi-4b-plus.dts base-commit: 009c9aa5be652675a06d5211e1640e02bbb1c33d -- 2.27.0
