The Amlogic P241 board is the Reference Design board for the S805X variant of the Amlogic Meson GXL SoC family.
The S805X is a variant of the Amlogic Meson GXL SoC family with the following physical limitations : - No SDCard interface - No GPIOCLK pins - No USB OTG ID pin (but Gadget feature can stil be forced) - No 5V regulator - Reduced ADC inputs (only ADC0 and ADC1) - GPIODV_26, GPIOAO_3, GPIOAO_4, GPIOAO_5, GPIOAO_6, GPIOX_14, GPIOX_15, GPIOH_3 are no more exposed on the package Amlogic exposes the following SW limitations : - HDMI max resolution should be 1080p60, VPU clock should be downgraded - Video Decoding should be limited to 1080p60, VDEC clock should be downgraded - CPU speed should be limited by SCPI OPP table to 1.2GHz - DRAM interface is limited to DDR4 16bit up to 1GiB The P241 board has the following features : - 1GiB DDR4 Memory - HDMI Connector with CEC - A/V jack with Stereo Audio and CVBS - 10/100 Ethernet - 2x USB2.0 Type-A - On-board WiFi SDIO Module - On-board eMMC storage - Infraread Received - Factory Reset button - UART connector Neil Armstrong (2): dt-bindings: amlogic: Add support for GXL S805X and the P241 board ARM64: dts: add S805X based P241 board Documentation/devicetree/bindings/arm/amlogic.txt | 6 + arch/arm64/boot/dts/amlogic/Makefile | 1 + .../boot/dts/amlogic/meson-gxl-s805x-p241.dts | 218 +++++++++++++++++++++ 3 files changed, 225 insertions(+) create mode 100644 arch/arm64/boot/dts/amlogic/meson-gxl-s805x-p241.dts -- 2.7.4
