2020-02-26drm/edid: Add flag to drm_display_info to identify HDMI sinksLaurent Pinchart3-0/+28
The drm_display_info structure contains many fields related to HDMI sinks, but none that identifies if a sink compliant with CEA-861 (EDID) shall be treated as an HDMI sink or a DVI sink. Add such a flag, and populate it according to section 8.3.3 ("DVI/HDMI Device Discrimination") of the HDMI v1.3 specification.

2020-02-26drm/connector: Add helper to get a connector type nameLaurent Pinchart2-0/+16
drm_connector.c contains a map of connector types (DRM_MODE_CONNECTOR_*) to name strings, but doesn't expose it. This leads to drivers having to store a similar map.

2020-02-16drm/pl111: Support Integrator IM-PD1 moduleLinus Walleij1-0/+73
The last in-kernel user of the old framebuffer driver is the IM-PD1 module for the Integrator/AP. Let's implement support for this remaining user so we can migrate the last user over to DRM and delete the old FB driver. On the Integrator/AP the IM-PD1 system controller will exist alongside the common Integrator system controller so make sure to do a special lookup for the IM-PD1 syscon and make it take precedence if found. Tested on the Integrator/AP with the IM-PD1 mounted.
