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/mcde: Fix off by 10^3 in calculation

2021-06-09T12:03:29+00:00

The calclulation of how many bytes we stuff into the DSI pipeline for video mode panels is off by three orders of magnitude because we did not account for the fact that the DRM mode clock is in kilohertz rather than hertz. This used to be: drm_mode_vrefresh(mode) * mode->htotal * mode->vtotal which would become for example for s6e63m0: 60 x 514 x 831 = 25628040 Hz, but mode->clock is 25628 as it is in kHz. This affects only the Samsung GT-I8190 "Golden" phone right now since it is the only MCDE device with a video mode display. Curiously some specimen work with this code and wild settings in the EOL and empty packets at the end of the display, but I have noticed an eeire flicker until now. Others were not so lucky and got black screens.

drm/mcde: Remove redundant error printing in mcde_dsi_probe()

2021-05-21T23:58:27+00:00

When devm_ioremap_resource() fails, a clear enough error message will be printed by its subfunction __devm_ioremap_resource(). The error information contains the device name, failure cause, and possibly resource information. Therefore, remove the error printing here to simplify code and reduce the binary size.

drm/mcde/panel: Inverse misunderstood flag

2021-03-04T13:31:06+00:00

A recent patch renaming MIPI_DSI_MODE_EOT_PACKET to MIPI_DSI_MODE_NO_EOT_PACKET brought to light the misunderstanding in the current MCDE driver and all its associated panel drivers that MIPI_DSI_MODE_EOT_PACKET would mean "use EOT packet" when in fact it means the reverse. Fix it up by implementing the flag right in the MCDE DSI driver and remove the flag from panels that actually want the EOT packet.
