Hi all, * Dave Gerlach <d-gerlach@xxxxxx> [150922 17:20]: > 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?
