Subject: [v3, 3/3] Documentation: dt: binding: fsl: Add 'fsl, ippdexpcr-alt-addr' property
Date: Tue, 24 Sep 2019 10:45:48 +0800 [thread overview]
Message-ID: <20190924024548.4356-3-biwen.li@nxp.com> (raw)
In-Reply-To: <20190924024548.4356-1-biwen.li@nxp.com>
The 'fsl,ippdexpcr-alt-addr' property is used to handle an errata A-008646
on LS1021A
Signed-off-by: Biwen Li <biwen.li@nxp.com>

Change in v3:
- rename property name
fsl,rcpm-scfg -> fsl,ippdexpcr-alt-addr
Change in v2:
- update desc of the property 'fsl,rcpm-scfg'
