This chip is not the same as A311D used in Vim3 board. Work based on Khadas 5.4 branch: https://github.com/khadas/linux/tree/khadas-vims-5.4.y The current status is Vim4 board booting to emergency shell via uart. Board Features: - 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 Changes Since v4: - Use S4 instead of G12a for uart fallback - Add OF_EARLYCON_DECLARE for T7 uart Changes Since v3: - Fix issues with "amlogic,meson-t7-uart" documentation Changes Since v2: - Add "amlogic,meson-t7-uart" documentation Changes Since v1: - Drop the T7 clock driver as it is not needed for serial boot. It will later use the S4 clock driver as S4 and T7 seems to be similar chips. - Use "arm,gic-400" for interrupt controller to fix dtb_check - Remove CPU node properties not needed for serial boot - Move UART node to apb4 node - Drop T7 UART compatible line and use S4 uart - Use psci V1 instead of 0.2, it works, but I can't verify is correct as the datasheet I have doesn't contain that information. - Remove compatible from meson-t7.dtsi, move it to vim4 board dts - Add memory node with 8GB. Not sure about this one, works without, but doesn't detect 8GB - Use defines for GIC_CPU_MASK_SIMPLE, IRQ_TYPE_LEVEL_LOW, IRQ_TYPE_LEVEL_HIGH instead of hardcoded values Lucas Tanure (4): dt-bindings: arm: amlogic: add Amlogic A311D2 bindings dt-bindings: serial: amlogic,meson-uart: Add compatible string for T7 tty: serial: meson: Add a earlycon for the T7 SoC arm64: dts: meson-t7-a311d2-khadas-vim4: add initial device-tree .../devicetree/bindings/arm/amlogic.yaml | 7 + .../bindings/serial/amlogic,meson-uart.yaml | 4 + arch/arm64/boot/dts/amlogic/Makefile | 1 + .../amlogic/meson-t7-a311d2-khadas-vim4.dts | 52 ++++++ arch/arm64/boot/dts/amlogic/meson-t7.dtsi | 158 ++++++++++++++++++ drivers/tty/serial/meson_uart.c | 2 + 6 files changed, 224 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-t7-a311d2-khadas-vim4.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-t7.dtsi --- 2.41.0
