Subject: [PATCH v2 2/2] arm64: dts: broadcom: bcm4908: Fix cpu node for smp boot
Date: Fri,  8 Jul 2022 11:25:07 -0700	[thread overview]
Message-ID: <20220708182507.23542-2-william.zhang@broadcom.com> (raw)
In-Reply-To: <20220708182507.23542-1-william.zhang@broadcom.com>

[-- Attachment #1: Type: text/plain, Size: 1090 bytes --]

Add spin-table enable-method and cpu-release-addr properties for
cpu0 node. This is required by all ARMv8 SoC. Otherwise some
bootloader like u-boot can not update cpu-release-addr and linux
fails to start up secondary cpus.

Fixes: 2961f69f151c ("arm64: dts: broadcom: add BCM4908 and Asus
GT-AC5300 early DTS files")

Signed-off-by: William Zhang <william.zhang@broadcom.com>
