Hi, This series is version 3 of the code to introduce a wkup_m3_ipc driver to handle communication between the MPU and Cortex M3 present on TI AM335x and AM437x SoCs. v2 of this series can be found at [1]. Only patch 3 has been changed based on a request from Tony and a few cleanups: - Rather than exporting all of the functionality of the driver, added wkup_m3_ipc_get and wkup_m3_ipc_put to allow users to just get a handle containing an ops structure for use. - Changed all ops (previously exported functions) to take pointer to struct wkup_m3_ipc as an argument now that user code will get this from wkup_m3_ipc_get. - General cleanup to probe function - Added MODULE_DEVICE_TABLE so driver can probe automatically. The series containing the DT nodes can be found here [2]. The actual dt nodes for wkup_m3_ipc (last two patches) have been merged but discussion is still open for the ti,mbox-send-noirq flag patches and depends on the comments provided for the omap-mailbox change presented in patch 1 of this series. A full branch containing all necessary PM code for both am335x and am437x has been pushed here [3] to provide a big picture view of the plan for this series. This driver relies on the firmware at [4] in the next-upstream branch being present in /lib/firmware in the rootfs or built in to the kernel.
