A1 is an application processor designed for smart audio and IoT applications, with Dual core ARM Cortex-A35 CPU. Unlike the previous GXL and G12 series, there is no Cortex-M3 AO CPU in it. This serial add basic support for the Amlogic A1 based Amlogic AD401 board: which describe components as follows: Reserve Memory, CPU, GIC, IRQ, Timer, UART. It's capable of booting up into the serial console. The pclk for uart_AO_B need to be fixed once A1 clock driver is merged. In this version, it rely on bootloader to enable the pclk gate Jianxin Pan (4): soc: amlogic: meson-gx-socinfo: Add A1 and A113L IDs dt-bindings: arm: amlogic: add A1 bindings dt-bindings: arm: amlogic: add Amlogic AD401 bindings arm64: dts: add support for A1 based Amlogic AD401 Documentation/devicetree/bindings/arm/amlogic.yaml | 6 + arch/arm64/boot/dts/amlogic/Makefile | 1 + arch/arm64/boot/dts/amlogic/meson-a1-ad401.dts | 30 +++++ arch/arm64/boot/dts/amlogic/meson-a1.dtsi | 121 +++++++++++++++++++++ drivers/soc/amlogic/meson-gx-socinfo.c | 2 + 5 files changed, 160 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-a1-ad401.dts create mode 100644 arch/arm64/boot/dts/amlogic/meson-a1.dtsi -- 2.7.4
