Subject: [PATCH v2] arm64: dts: fix endianness issue of rcpm
Date: Tue, 29 Sep 2020 09:30:21 +0800 [thread overview]
Message-ID: <20200929013021.46395-1-ran.wang_1@nxp.com> (raw)
From: Biwen Li <biwen.li@nxp.com>
Add little-endian property to RCPM node (for ls1028a,ls1088a,ls208xa),
otherwise RCPM driver will program hardware with incorrect setting,
causing system (such as LS1028ARDB) failed to be waked by wakeup source.
Fixes: 791c88ca5713 (“arm64: dts: ls1028a: Add ftm_alarm0 DT node”)
Fixes: f4fe3a8665495 (“arm64: dts: layerscape: add ftm_alarm0 node”)
