[PATCH v2] mailbox: Remove mailbox_client.h from controller drivers

From: Peng Fan (OSS)

Date: Wed Jan 28 2026 - 07:33:13 EST


From: Peng Fan <peng.fan@xxxxxxx>

mailbox_client.h should be used by mailbox consumer drivers, not mailbox
controller (provider) drivers. The affected drivers do not use any mailbox
client APIs, so the include can be safely removed.
