Subject: [PATCH v1 0/2] arm64: dts: ti: k3-am62: Add MCU MCAN

From: Francesco Dolcini <francesco.dolcini@...adex.com>

On AM62x there are no hardware interrupts routed to A53 GIC
interrupt controller for MCU MCAN IPs, so MCU MCAN nodes were
omitted from MCU dtsi.

Timer polling was introduced in commits [1][2] so now add MCU MCAN nodes
to the MCU dtsi for Cortex A53.

[1] b382380c0d2d ("can: m_can: Add hrtimer to generate software interrupt")
[2] bb410c03b999 ("dt-bindings: net: can: Remove interrupt properties for MCAN")

Once the MCU MCANs are added to the SOC dtsi, enable the Verdin CAN2.
