[PATCH v4 0/4] Add basic support for Mediatek MT8173 SoC

[PATCH v4 0/4] Add basic support for Mediatek MT8173 SoC

[Eddie Huang]

MT8173 is a SoC based on 64bit ARMv8 architecture. It contains 2 CA53 + 2 CA57 cores.
MT8173 share many HW IP with MT8135 and other MT65xx series. This patchset was tested
on MT8173 engineer sample, and boot to shell ok.

This series contains document bindings, device tree, defconfig, and one sysirq
modification for MT8173.

Changes in v4:
1. Add sysirq, uart binding documents.
2. Disable UART in mt8173.dtsi, enable needed UART in mt8173-evb.dtsi

This patch base on 3.19-rc1, Joe's sysirq patch [1] and test boot to shell with
Catalin Marinas's arch_timer virtual counter patch [2]

[PATCH v4 2/4] irqchip: mtk-sysirq: Get irq number from register resource size

[Eddie Huang]

From: Yingjoe Chen <yingjoe.chen@mediatek.com>

Originally mtk-sysirq hardcoded supported irq number to 224. This
was fine since all SoCs before support the same number of irqs for
intpol.

However MT8173 intpol support 32 more irq pins, changes to get
irq number from register resource size to suppor MT8173 properly.
