Subject: [PATCH v3 4/7] ARM: dts: lan966x: add all flexcom usart nodes
Date: Tue,  5 Apr 2022 18:08:34 +0200	[thread overview]
Message-ID: <20220405160837.4093563-5-michael@walle.cc> (raw)
In-Reply-To: <20220405160837.4093563-1-michael@walle.cc>

Add all the remaining usart nodes for the flexcom block. Although the
DMA channels are specified, DMA is not enabled by default because break
detection doesn't work with DMA.

Keep the nodes disabled by default.
