This patchset aimed to add minimal support for the Amlogic P212 reference board from Amlogic based on the Meson S905X SoC from the Meson GXL SoC Family.
The initial support is composed of : - GXL pinctrl driver - Minimal boot support with serial, MMC and SDCard - Updated DTS from Linux 4.13.5
Commands to generate a valid binary are provided in the board README.
The following work will be pushed later on : - Support for dynamic reading of DDR memory size from registers - Support for the Internal Ethernet PHY is WiP - USB DWC3 Host Support with PHY support
This patchset can boot Linux Mainline 4.14-rc4 with the Video Pipeline disables, since it currently depends on Power Domains initialization from Vendor u-boot. Dedicated reset and init code for the Video Pipeline for mainline Linux is in the work.
