arm64: dts: ti: k3-am62: Add MCU MCAN nodes
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 the Cortex A53. [1] commit b382380c0d2d ("can: m_can: Add hrtimer to generate software interrupt") [2] commit bb410c03b999 ("dt-bindings: net: can: Remove interrupt properties for MCAN") [fd: fixed labels to match datasheet numbering, revised commit message, fixed reg/reg-names order] Signed-off-by: Judith Mendez <[email protected]> Signed-off-by: Francesco Dolcini <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Nishanth Menon <[email protected]>
