2020-06-26drm/bridge: ti-sn65dsi86: ensure bridge suspend happens during PM sleepHarigovindan P1-0/+2
ti-sn65dsi86 bridge is enumerated as a runtime device. When suspend is triggered, PM core adds a refcount on all the devices and calls device suspend, since usage count is already incremented, runtime suspend will not be called and it kept the bridge regulators and gpios ON which resulted in platform not entering into XO shutdown. Add changes to force suspend on the runtime device during pm sleep.

2020-06-26drm/debug: Expose connector VRR monitor range via debugfsBhanuprakash Modem1-0/+22

2020-06-24drm/mipi-dbi: Remove ->enabledDaniel Vetter4-32/+12
The atomic helpers try really hard to not lose track of things, duplicating enabled tracking in the driver is at best confusing. Double-enabling or disabling is a bug in atomic helpers. In the fb_dirty function we can just assume that the fb always exists, simple display pipe helpers guarantee that the crtc is only enabled together with the output, so we always have a primary plane around. Now in the update function we need to be a notch more careful, since that can also get called when the crtc is off. And we don't want to upload frames when that's the case, so filter that out too.

2020-06-23drm: bridge: adv7511: Make connector creation optionalLaurent Pinchart1-8/+5
Now that the driver supports all the connector-related bridge operations, make the connector creation optional. This enables usage of the adv7511 with the DRM bridge connector helper.

2020-06-23drm: bridge: adv7511: Implement bridge connector operationsLaurent Pinchart1-4/+39
Implement the bridge connector-related .get_edid(), .detect() and .hpd_notify() operations, and report the related bridge capabilities. Output status detection is implemented using the same backend as for the DRM connector, but requires making mode retrieval at detection time optional as no pointer to the connector is available to the bridge .detect() operation. The reason for the need to retrieve modes at detection time is unclear to me, and this may benefit from further refactoring of hot plug handling code. Hot plug detection is notified through the bridge HPD notification framework when the bridge is used without creating a connector, and falls back to the existing implementation otherwise. CEC handling of disconnection is handled in the new .hpd_notify() operation in the new code path.

Function prepare_igt_frag() and get_insert_time() were casting signed value to unsigned value before returning error.
