linux-toradex.git/include/linux/wkup_m3_ipc.h, branch v4.9.14 Linux kernel for Apalis and Colibri modules soc: ti: Add wkup_m3_ipc driver 2015-12-03T15:24:29+00:00 Dave Gerlach d-gerlach@ti.com 2015-09-23T00:14:54+00:00 cdd5de500b2c90d5181ebc963826019a0a4234ba Introduce a wkup_m3_ipc driver to handle communication between the MPU and Cortex M3 wkup_m3 present on am335x. This driver is responsible for actually booting the wkup_m3_rproc and also handling all IPC which is done using the IPC registers in the control module, a mailbox, and a separate interrupt back from the wkup_m3. A small API is exposed for executing specific power commands, which include configuring for low power mode, request a transition to a low power mode, and status info on a previous transition.
