MT8183 is a SoC based on 64bit ARMv8 architecture.
It contains 4 CA53 and 4 CA73 cores.
MT8183 share many HW IP with MT65xx series.
This patchset was tested on MT8183 evaluation board, and boot to shell ok.
This series contains document bindings, device tree including interrupt, uart.
Change in v2:
1. Split dt-bindings into different patches
2. Correct bindings for supported SoCs (mtk-uart.txt)
Ben Ho (1):
arm64: dts: Add Mediatek SoC MT8183 and evaluation board dts and
Makefile
Erin Lo (3):
dt-bindings: arm: Add bindings for Mediatek MT8183 SoC Platform
dt-bindings: mtk-sysirq: Add compatible for Mediatek MT8183
dt-bindings: serial: Add compatible for Mediatek MT8183
