Please double check again if you use the R-b tags correctly. I have provided my R-b tag before but have some more minor comments below. With the minor comments: Reviewed-by: Tzung-Bi Shih <tzungbi@google.com>

To be neat, I think use mtk_adsp for all names looks better. I.e. s/adsp_ipc_send/mtk_adsp_ipc_send/.
+static void adsp_ipc_recv(struct mbox_client *c, void *msg) +{
Ditto, mtk_adsp_ipc_recv looks better to me.

Ditto, mtk_adsp_mbox_ch_info.

mtk_adsp_ipc_set_data, although there is no use case yet.
+static inline void *adsp_ipc_get_data(struct mtk_adsp_ipc *ipc) +{
mtk_adsp_ipc_get_data, although there is no use case yet.
