[PATCH v2 0/5] arm64: bcmbca: add bcm63158 soc support under bcmbca arch

[William Zhang]

[-- Attachment #1.1: Type: text/plain, Size: 1477 bytes --]

This change adds the basic support for Broadcom's ARM64 based
Broadband SoC BCM63158. The initial support includes a bare-bone dts
for quad core ARM A53 with a ARM PL011 uart. Linux kernel image can be
built with the ARM64 defconfig.

Changes in v2:
- Simplify dt-bindings patch subject line
- Change internal bus address and size cells from 2 to 1
- Fix pmu compatible string
- Remove unnecessary cpu_on and cpu_off properties from psci node
- Add the missing gic registers and interrupts property to gic node
