    Subject[PATCH v8 0/3] firmware: mtk: add adsp ipc protocol for SOF
    Date
    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 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

    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:

    - remove useless MODULE_LICENSE
    - change label name to out_free
