Thank you! [1/2] arm64: dts: ti: k3-j722s-main: Add R5F and C7x remote processor nodes commit: 05b1653c4fc148189743e4b3cbef798e49db61f0 [2/2] arm64: dts: ti: k3-j722s-evm: Enable Inter-Processor Communication commit: 5b035d14a508efd065895607ae7a6f913b26fef8 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
Hello All, The K3 J722S SoCs have one single-core Arm Cortex-R5F processor in each of the WAKEUP, MCU and MAIN voltage domain, and two C71x DSP subsystems in MAIN voltage domain. Thus, this series adds the DT Nodes for the remote processors to add support for IPC. This series also enables IPC on the J722S-EVM platform based on the above SoC by adding the mailbox instances, shared memory carveouts and reserving the conflicting timer nodes (as they are used by remoteproc firmware). v5: Changelog: - Collected Reviewed-by tags from Udit and Andrew given in v4 version of patch ("arm64: dts: ti: k3-j722s-main: Add R5F and C7x remote processor nodes") * Udit 1) Updated commit message to correctly reflect the host core name (A53 not A72) in patch "arm64: dts: ti: k3-j722s-evm: Enable Inter-Processor Communication" 2) Updated mbox DT node label and name to "mbox_wkup_r5_0" from "mbox_r5_0" for clarity in patch "arm64: dts: ti: k3-j722s-evm: Enable Inter-Processor Communication" Link to v4: https://lore.kernel.org/all/20240829060932.3441295-1-b-padhi@ti.com/ v4: Changelog: * Nishanth: 1) Fixed DT node properties order to put standard properties before vendor specific properties in patch "arm64: dts: ti: k3-j722s-main: Add R5F and C7x remote processor nodes" 2) Put "status" property at the end in extended DT nodes and preceded child nodes with a single blank line wherever applicable in patch "arm64: dts: ti: k3-j722s-evm: Enable Inter-Processor Communication" following kernel DTS coding style. Link to v3: https://lore.kernel.org/all/20240828112713.2668526-1-b-padhi@ti.com/ v3: Changelog: 1) Reserved conflicting Timer Nodes in k3-j722s-evm.dts file to avoid remotecore boot failures. Link to v2: https://lore.kernel.org/all/20240612112259.1131653-1-b-padhi@ti.com/ v2: Changelog: 1) Addressed Andrew's comments to refactor remotecore nodes into k3-j722s-main.dtsi file. 2) Squashed Patch 2 and 3 from V1 into Patch 2 in V2 as they were doing the same logical thing. 3) The DTBs check warnings from V1 are automatically fixed after a dt-binding patch[0] was merged in linux-next.
