Subject: [PATCH v1 5/6] ARM: dts: lan966x: add flexcom I2C nodes
Date: Thu, 3 Mar 2022 17:03:22 +0100 [thread overview]
Message-ID: <20220303160323.3316317-6-michael@walle.cc> (raw)
In-Reply-To: <20220303160323.3316317-1-michael@walle.cc>
Add all I2C nodes of the flexcom IP blocks. The driver supports
FIFO, DMA or both combined. But the latter isn't working correctly.
Thus, skip the fifo-size property for now. DMA is doing single byte
reads in this case.
Keep the nodes disabled by default.
