Define SRAM, mailbox and ACPM protocol in device tree. Enable the mailbox and ACPM protocol in defconfig. Changes in v3: - ACPM: don't specify the channel ID and type in DT: the channel ID is discovered at runtime and the channel type is always DOORBELL for the ACPM interface. - mbox: update #mbox-cells = <0>; - rebase on top of v6.13-rc3 - Link to v2: https://lore.kernel.org/r/20241212-b4-acpm-v4-upstream-dts-v2-0-91b7a6f6d0b0@xxxxxxxxxx Changes in v2: - update nodes based on the bindings updates - update mailbox and power-management (mailbox client) nodes to specify channel type (doorbell or data) and channel ID. v1: Link: https://lore.kernel.org/linux-arm-kernel/20241205180200.203146-1-tudor.ambarus@xxxxxxxxxx/ Signed-off-by: Tudor Ambarus <tudor.ambarus@xxxxxxxxxx> --- Tudor Ambarus (4): arm64: dts: exynos: gs101: add SRAM node arm64: dts: exynos: gs101: add AP to APM mailbox node arm64: dts: exynos: gs101: add ACPM protocol node arm64: defconfig: enable ACPM protocol and Exynos mailbox arch/arm64/boot/dts/exynos/google/gs101.dtsi | 25 +++++++++++++++++++++++++ arch/arm64/configs/defconfig | 2 ++ 2 files changed, 27 insertions(+) --- base-commit: 78d4f34e2115b517bcbfe7ec0d018bbbb6f9b0b8 change-id: 20241220-gs101-acpm-dt-6dcde166530a Best regards, -- Tudor Ambarus <tudor.ambarus@xxxxxxxxxx>
