BTW, as I asked on patch 2, Khadas asked me to rename the board to "vim3l", which is the commercial name, should I only change the DT name or also the compatible "khadas,vim3l" ? Neil

Add the Amlogic SM1 based Khadas VIM3, sharing all the same features as the G12B based one, but: - a different DVFS support since only a single cluster is available - audio is still not available on SM1 Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> --- arch/arm64/boot/dts/amlogic/Makefile | 1 + .../dts/amlogic/meson-sm1-khadas-vim3.dts | 69 +++++++++++++++++++ 2 files changed, 70 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-sm1-khadas-vim3.dts
