arm64: dts: amlogic-t7-a311d2-khadas-vim4: add initial device-tree
The Khadas VIM4 uses the Amlogic A311D2 SoC, based on the Amlogic T7 SoC family, on a board with the same form factor as the VIM3 models. - 8GB LPDDR4X 2016MHz - 32GB eMMC 5.1 storage - 32MB SPI flash - 10/100/1000 Base-T Ethernet - AP6275S Wireless (802.11 a/b/g/n/ac/ax, BT5.1) - HDMI 2.1 video - HDMI Input - 1x USB 2.0 + 1x USB 3.0 ports - 1x USB-C (power) with USB 2.0 OTG - 3x LED's (1x red, 1x blue, 1x white) - 3x buttons (power, function, reset) - M2 socket with PCIe, USB, ADC & I2C - 40pin GPIO Header - 1x micro SD card slot Signed-off-by: Lucas Tanure <tanure@linux.com> Link: https://lore.kernel.org/r/20230629073419.207886-5-tanure@linux.com Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Signed-off-by: Neil Armstrong <neil.armstrong@linaro.org>
