Subject: [PATCH v4 4/6] arm64: dts: ti: k3-j721e-common-proc-board: Add support for mcu and main mcan nodes
From: Faiz Abbas <faiz_abbas@...com>
Add four MCAN nodes present on the common processor board and set a
maximum data rate of 5 Mbps. Disable all other nodes as they
are not brought out on the common processor board.
