Message

This patch provides mediatek adsp ipc support for SOF.
ADSP IPC protocol offers (send/recv) interfaces using
mediatek-mailbox APIs.

This patch was tested and confirmed to work with SOF fw on 
MT8195 cherry board and MT8186 krabby board.

changes since v8:
- fix patchset 2 and 3.
  move "depends on MTK_ADSP_IPC" from SND_SOC_SOF_MTK_COMMON
  to SND_SOC_SOF_MT8195/MT8186 to prevent generating wrong
  config.

changes since v7:
- rebase to linux-next/next-22020504
- use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL in mtk-adsp-ipc.c 
- move mtk-adsp-ipc.c out from driver/firmware/mediatek
- add user of mtk-adsp-ipc.h in patchset 2 and 3.

changes since v6:
- rebase to matthias.bgg/linux.git, v5.18-next/soc
- Prefer "GPL" over "GPL v2" for MODULE_LICENSE

changes since v5:
- fix WARNING: modpost: missing MODULE_LICENSE() in drivers/mailbox
  /mtk-adsp-mailbox.o. Add MODULE_LICENSE in the last line.
- Due to WARNING: Missing or malformed SPDX-License-Identifier tag
  in line 1 in checkpatch, we don't remove SPDX-License in line 1.

changes since v4:
- add error message for wrong mbox chan

changes since v3:
- rebase on v5.16-rc8
- update reviewers

changes since v2:
- add out tag for two memory free phases

changes since v1:
- add comments for mtk_adsp_ipc_send and mtk_adsp_ipc_recv
- remove useless MODULE_LICENSE
- change label name to out_free

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a 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.

Thanks,
Mark
