I understand the dependency, it does create a dtbs_check warnings on rc1, but I am picking this up since the yaml fixup is in next already and not a new compatible addition. if the fixups does'nt end up in linus-master for 6.6-rc1, we might need to look at what we need to do.

[1/2] arm64: dts: ti: k3-am62: Add MCU MCAN nodes commit: 108f61e03963a3a019486fd80cc84d5db5c204d0 [2/2] arm64: dts: ti: k3-am625-verdin: enable CAN_2 commit: 7480cea33b4c36aeffe592eb6f151bc9974fee70 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. [1] https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git
From: Francesco Dolcini <francesco.dolcini@toradex.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] commit b382380c0d2d ("can: m_can: Add hrtimer to generate software interrupt") [2] commit bb410c03b999 ("dt-bindings: net: can: Remove interrupt properties for MCAN") Once the MCU MCANs are added to the SOC dtsi, enable the Verdin CAN2. v1..v2: - fixed can node name - added commit prefix before sha in commit message Hiago De Franco (1): arm64: dts: ti: k3-am625-verdin: enable CAN_2 Judith Mendez (1): arm64: dts: ti: k3-am62: Add MCU MCAN nodes arch/arm64/boot/dts/ti/k3-am62-mcu.dtsi | 24 +++++++++++++++++++ .../boot/dts/ti/k3-am62-verdin-dahlia.dtsi | 5 ++++ .../arm64/boot/dts/ti/k3-am62-verdin-dev.dtsi | 5 ++++ .../boot/dts/ti/k3-am62-verdin-yavia.dtsi | 5 ++++ arch/arm64/boot/dts/ti/k3-am62-verdin.dtsi | 19 +++++++++++++-- 5 files changed, 56 insertions(+), 2 deletions(-)
