NXP's i.MX8 SoCs have system controller (M4 core) which takes control of timer management, including watchdog, srtc and system counter etc., other clusters like Cortex-A35 can send out command via MU (Message Unit) to system controller for timer operation. This patch adds timer IPC(inter-processor communication) support. Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
