drm: Don't make DRM_PANEL_BRIDGE dependent on DRM_KMS_HELPERS

2022-03-17T10:07:57Z

Fix a number of undefined references to drm_kms_helper.ko in drm_dp_helper.ko: arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_duplicate_state': drm_dp_mst_topology.c:(.text+0x2df0): undefined reference to `__drm_atomic_helper_private_obj_duplicate_state' arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_delayed_destroy_work': drm_dp_mst_topology.c:(.text+0x370c): undefined reference to `drm_kms_helper_hotplug_event' arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_up_req_work': drm_dp_mst_topology.c:(.text+0x7938): undefined reference to `drm_kms_helper_hotplug_event' arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_link_probe_work': drm_dp_mst_topology.c:(.text+0x82e0): undefined reference to `drm_kms_helper_hotplug_event' This happens if panel-edp.ko has been configured with DRM_PANEL_EDP=y DRM_DP_HELPER=y DRM_KMS_HELPER=m which builds DP helpers into the kernel and KMS helpers sa a module. Making DRM_PANEL_EDP select DRM_KMS_HELPER resolves this problem. To avoid a resulting cyclic dependency with DRM_PANEL_BRIDGE, don't make the latter depend on DRM_KMS_HELPER and fix the one DRM bridge drivers that doesn't already select DRM_KMS_HELPER. As KMS helpers cannot be selected directly by the user, config symbols should avoid depending on it anyway.

drm/panel: simple: Fix Innolux G070Y2-L01 BPP settings

2022-03-16T15:35:05Z

The Innolux G070Y2-L01 supports two modes of operation: 1) FRC=Low/NC ... MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ... BPP=6 2) FRC=High ..... MEDIA_BUS_FMT_RGB888_1X7X4_SPWG ... BPP=8 Currently the panel description mixes both, BPP from 1) and bus format from 2), which triggers a warning at panel-simple.c:615. Pick the later, set bpp=8, fix the warning.

drm/imx: parallel-display: Remove bus flags check in imx_pd_bridge_atomic_check()

2022-03-16T15:35:04Z

If display timings were read from the devicetree using of_get_display_timing() and pixelclk-active is defined there, the flag DISPLAY_FLAGS_SYNC_POSEDGE/NEGEDGE is automatically generated. Through the function drm_bus_flags_from_videomode() e.g. called in the panel-simple driver this flag got into the bus flags, but then in imx_pd_bridge_atomic_check() the bus flag check failed and will not initialize the display. The original commit fe141cedc433 does not explain why this check was introduced. So remove the bus flags check, because it stops the initialization of the display with valid bus flags.

drm/mgag200: Fix PLL setup for g200wb and g200ew

2022-03-13T19:35:06Z

commit f86c3ed55920 ("drm/mgag200: Split PLL setup into compute and update functions") introduced a regression for g200wb and g200ew. The PLLs are not set up properly, and VGA screen stays black, or displays "out of range" message. MGA1064_WB_PIX_PLLC_N/M/P was mistakenly replaced with MGA1064_PIX_PLLC_N/M/P which have different addresses.

It turns out that DE3 manual has inverted YUV and YVU format numbers for P010 and P210. Invert them. This was tested by playing video decoded to P010 and additionally confirmed by looking at BSP driver source.

drm/i915/psr: Set "SF Partial Frame Enable" also on full update

2022-03-07T14:45:31Z

Currently we are observing occasional screen flickering when PSR2 selective fetch is enabled. More specifically glitch seems to happen on full frame update when cursor moves to coords x = -1 or y = -1. According to Bspec SF Single full frame should not be set if SF Partial Frame Enable is not set. This happened to be true for ADLP as PSR2_MAN_TRK_CTL_ENABLE is always set and for ADL_P it's actually "SF Partial Frame Enable" (Bit 31). Setting "SF Partial Frame Enable" bit also on full update seems to fix screen flickering. Also make code more clear by setting PSR2_MAN_TRK_CTL_ENABLE only if not on ADL_P. Bit 31 has different meaning in ADL_P.
