drm/bridge: anx7625: Propagate errors from sp_tx_edid_read()

2021-08-18T18:57:03+00:00

During the sp_tx_edid_read() call the return value of sp_tx_edid_read() is ignored, which could cause potential errors to go unhandled. All errors which are returned by sp_tx_edid_read() are handled in anx7625_get_edid().

drm/bridge: anx7625: Tune K value for IVO panel

2021-08-06T10:48:54+00:00

IVO panel require less input video clock variation than video clock variation in DP CTS spec. This patch decreases the K value of ANX7625 which will shrink eDP Tx video clock variation to meet IVO panel's requirement.

drm/bridge: Centralize error message when bridge attach fails

2021-07-28T13:33:12+00:00

Being informed of a failure to attach a bridge is useful, and many drivers prints an error message in that case. Move the message to drm_bridge_attach() to avoid code duplication. Suggested-by: Stephen Boyd Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Reviewed-by: Jyri Sarha

drm/dsi: Add _NO_ to MIPI_DSI_* flags disabling features

2021-07-27T07:48:24+00:00

Many of the DSI flags have names opposite to their actual effects, e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually be disabled. Fix this by including _NO_ in the flag names, e.g. MIPI_DSI_MODE_NO_EOT_PACKET.

drm/bridge: anx7625: Make hpd workqueue freezable

2021-06-18T12:23:15+00:00

There were still a race condition between hpd work and suspend, since the workqueue work can still be run after anx7625 had powered off in suspend. Since we never want hpd work to run while suspending, and there's no harm to delay them to be run after resume, mark the workqueue as WQ_FREEZABLE so all works won't run while suspending.

drm/bridge: anx7625: Synchronously run runtime suspend.

2021-05-20T10:27:20+00:00

Originally when using pm_runtime_put, there's a chance that the runtime suspend hook will be run after the following anx7625_bridge_mode_set call, resulting in the display_timing_valid field to be cleared, and the following power on fail. Change all pm_runtime_put to pm_runtime_put_sync, so all power off operations are guaranteed to be done after the call returns.
