[ Upstream commit 812f0116c66a3ebaf0b6062226aa85574dd79f67 ]
The System Controller Firmware (SCFW) is a low-level system function which runs on a dedicated Cortex-M core to provide power, clock, and resource management. It exists on some i.MX8 processors. e.g. i.MX8QM (QM, QP), and i.MX8QX (QXP, DX). SCU driver manages the IPC interface between host CPU and the SCU firmware running on M4.
For i.MX8QM, stop mode request is controlled by System Controller Unit(SCU) firmware, this patch introduces FLEXCAN_QUIRK_SETUP_STOP_MODE_SCFW quirk for this function.

This is adding a new feature and not fixing a bug.
Why does it qualify for stable inclusion?
