MT2712 is a SoC based on 64bit ARMv8 architecture.
MT2712 share many HW IP with MT8173. This patchset was tested on MT2712
evaluation board, and boot to shell ok.
This series contains document bindings, device tree including interrupt
and uart.
Changes compared to v2:
- remove alias from serial1 to serial5
- remove initrd-start and initrd-end
- change GIC_CPU_MASK_SIMPLE(6) to GIC_CPU_MASK_RAW(0x13)
- change gic-400 reg range
Changes compared to v1:
- change subject prefix for bindings
- change device tree license to SPDX tag.
- change bootargs parameter to DT usage.
- change intpol-controller to interrupt-controller
