Subject: [PATCH v2 1/2] arm64: dts: broadcom: bcm4908: Fix timer node for BCM4906 SoC
Date: Fri,  8 Jul 2022 11:25:06 -0700	[thread overview]
Message-ID: <20220708182507.23542-1-william.zhang@broadcom.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 1286 bytes --]

The cpu mask value in interrupt property inherits from bcm4908.dtsi
which sets to four cpus. Correct the value to two cpus for dual core
BCM4906 SoC.

Fixes: c8b404fb05dc ("arm64: dts: broadcom: bcm4908: add BCM4906
Netgear R8000P DTS files")
