Re: [PATCH v2] drm/omap: force runtime PM suspend on system suspend

* Tomi Valkeinen tomi.valkeinen@ti.com [200618 09:53]:

Use SET_LATE_SYSTEM_SLEEP_PM_OPS in DSS submodules to force runtime PM suspend and resume.

We use suspend late version so that omapdrm's system suspend callback is called first, as that will disable all the display outputs after which it's safe to force DSS into suspend.

This would be great to have merged as a fix for v5.8 as it fixes a suspend and resume regression:
