Yes the configuration appear to be similar but there always the same. When they are, it is usually by lack of knowledge of the platform and its use cases. Using the same sound card model is particularily bad. > arm64: dts: meson: convert ugoos-am6 to common w400 dtsi > arm64: dts: meson: convert odroid-n2 to hdmi dtsi > arm64: dts: meson: convert khadas-vim3/vim3l to hdmi dtsi For example on the vim3, copying the sei610 was not the best choice possible. - SEI 610 prepares TDM B for 8 ch HDMI because TDM A is used for the internal speaker - VIM3 has the TDM B on the 40 pin header and TDM C on the M2 port. It would be better to use TDM A for HDMI is this case (patch will follow) This is just an example. Bottom, it designs are really copy/paste of the ref design, the dtsi should include all the platform, not just the sound. > arm64: dts: meson: convert x96max to hdmi dtsi > > .../amlogic/meson-g12-audio-hdmi-spdif.dtsi | 139 +++++ > .../dts/amlogic/meson-g12-audio-hdmi.dtsi | 96 ++++ > .../boot/dts/amlogic/meson-g12a-x96-max.dts | 131 +---- > .../dts/amlogic/meson-g12b-khadas-vim3.dtsi | 85 --- > .../boot/dts/amlogic/meson-g12b-odroid-n2.dts | 89 +-- > .../boot/dts/amlogic/meson-g12b-ugoos-am6.dts | 541 +----------------- > .../boot/dts/amlogic/meson-g12b-w400.dtsi | 423 ++++++++++++++ > .../boot/dts/amlogic/meson-khadas-vim3.dtsi | 1 + > 8 files changed, 663 insertions(+), 842 deletions(-) > create mode 100644 arch/arm64/boot/dts/amlogic/meson-g12-audio-hdmi-spdif.dtsi > create mode 100644 arch/arm64/boot/dts/amlogic/meson-g12-audio-hdmi.dtsi > create mode 100644 arch/arm64/boot/dts/amlogic/meson-g12b-w400.dtsi
