Subject[PATCH 0/2] Add support for S805X based P241 Reference Design board
Date
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
