drm: Don't make DRM_PANEL_BRIDGE dependent on DRM_KMS_HELPERS

2022-03-17T10:07:57+00:00

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

2022-03-16T15:35:05+00:00

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/panel: Select DRM_DP_HELPER for DRM_PANEL_EDP

2022-03-12T07:41:30+00:00

As reported in [1], DRM_PANEL_EDP depends on DRM_DP_HELPER. Select
the option to fix the build failure. The error message is shown
below.

  arm-linux-gnueabihf-ld: drivers/gpu/drm/panel/panel-edp.o: in function
    `panel_edp_probe': panel-edp.c:(.text+0xb74): undefined reference to

The issue has been reported before, when DisplayPort helpers were
hidden behind the option CONFIG_DRM_KMS_HELPER. [2]

drm/panel: simple: Assign data from panel_dpi_probe() correctly

2022-02-06T09:55:42+00:00

In the function panel_simple_probe() the pointer panel->desc is
assigned to the passed pointer desc. If function panel_dpi_probe()
is called panel->desc will be updated, but further on only desc
will be evaluated. So update the desc pointer to be able to use
the data from the function panel_dpi_probe().

2021-12-07T16:14:26+00:00

At present, we have enough panel to confirm the effect,
update the initial code to achieve the best effect.
Such as gamma, Gop timing. They are all minor modifications
and doesn't affect the lighting of the panel.

a)Boe-tv110c9m panel Optimized touch horizontal grain.
b)Inx-hj110iz panel Optimized GOP timing and gamma.

drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

2021-11-30T10:10:03+00:00

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER
has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting
KMS helpers and CMA will now automatically enable CMA KMS helpers.

Some drivers' Kconfig files did not correctly select KMS or CMA helpers.
Fix this as part of the change.

The edp_panel_entry members 'delay' and 'name' are documented, but
without the correct syntax for kernel doc.

This generates the following warnings:

drivers/gpu/drm/panel/panel-edp.c:204: warning: Function parameter or member 'name' not described in 'edp_panel_entry'
