    Subject[PATCH v3 0/3] soc: ti: Introduce wkup_m3_ipc driver
    Date
    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.

    Regards,
    Dave
