Subject: [RFC 20/27] PCI: dwc/keystone: Drop duplicated 'num-viewport'
Date: Mon, 3 Aug 2020 15:01:09 -0600 [thread overview]
Message-ID: <20200803210116.3132633-21-robh@kernel.org> (raw)
In-Reply-To: <20200803210116.3132633-1-robh@kernel.org>
The DWC core driver already parses and stores the 'num-viewport' DT
property, so there is no need for the Keystone driver to store it.
