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.
Anybody got comments on this one? Should I pick up this series or
what's the plan?
Now that Patch 1 has been merged [1] can patch 2 and 3 be picked up?
These apply cleanly on v4.4-rc3.
Regards,
Dave
