2021-01-05drm: rcar-du: Skip encoder allocation for LVDS1 in dual-link modeLaurent Pinchart1-34/+25
The rcar-du driver skips registration of the encoder for the LVDS1 output when LVDS is used in dual-link mode, as the LVDS0 and LVDS1 links are bundled and handled through the LVDS0 output. It however still allocates the encoder and immediately destroys it, which is pointless. Skip allocation of the encoder altogether in that case.

2021-01-05drm: rcar-du: Fix crash when using LVDS1 clock for CRTCLaurent Pinchart3-12/+9
On D3 and E3 platforms, the LVDS encoder includes a PLL that can generate a clock for the corresponding CRTC, used even when the CRTC output to a non-LVDS port. This mechanism is supported by the driver, but the implementation is broken in dual-link LVDS mode. In that case, the LVDS1 drm_encoder is skipped, which causes a crash when trying to access its bridge later on. Fix this by storing bridge pointers internally instead of retrieving them from the encoder. The rcar_du_device encoders field isn't used anymore and can be dropped.

2021-01-05drm: Add default modes for connectors in unknown stateLaurent Pinchart1-1/+2
The DRM CRTC helpers add default modes to connectors in the connected state if no mode can be retrieved from the connector. This behaviour is useful for VGA or DVI outputs that have no connected DDC bus. However, in such cases, the status of the output usually can't be retrieved and is reported as connector_status_unknown. Extend the addition of default modes to connectors in an unknown state to support outputs that can retrieve neither the modes nor the connection status.

2020-12-18drm/i915/tgl: Fix REVID macros for TGL to fetch correct steppingAditya Swarup1-6/+6
Fix TGL REVID macros to fetch correct display/gt stepping based on SOC rev id from INTEL_REVID() macro. Previously, we were just returning the first element of the revid array instead of using the correct index based on SOC rev id.

2020-12-18drm/i915: Fix mismatch between misplaced vma check and vma insertChris Wilson1-1/+1
When inserting a VMA, we restrict the placement to the low 4G unless the caller opts into using the full range. This was done to allow usersapce the opportunity to transition slowly from a 32b address space, and to avoid breaking inherent 32b assumptions of some commands. However, for insert we limited ourselves to 4G-4K, but on verification we allowed the full 4G. This causes some attempts to bind a new buffer to sporadically fail with -ENOSPC, but at other times be bound successfully. commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1 page") suggests that there is a genuine problem with stateless addressing that cannot utilize the last page in 4G and so we purposefully excluded it. This means that the quick pin pass may cause us to utilize a buggy placement.
