> 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 . 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 . 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  to provide a big picture view of the plan for
> this series.
> This driver relies on the firmware at  in the next-upstream branch
> being present in /lib/firmware in the rootfs or built in to the kernel.
Anybody got comments on this one? Should I pick up this series or
what's the plan?
