Hi! The background for these patches is that our PCB interface between the SAMA5D3 and the ds90c185 lvds encoder is only using 16 bits, and this has to be described somewhere, or the atmel-hlcdc driver have no chance of selecting the correct output mode. Since we have similar problems with a tda19988 HDMI encoder I added patches to override the atmel-hlcdc output format via DT properties compatible with the media video-interface binding and things start to play together. Cheers, Peter Changes since v6 https://lkml.org/lkml/2018/8/3/333 - zap bus-type from the binding in patch 2/3 Changes since (the shortened) v5 https://lkml.org/lkml/2018/8/3/182 - add reg properties (and #*-cells) to the example in patch 2/3 - prohibit bus-width 0 in the device-tree in patch 3/3 - added reviewed-by from Jacopo to patch 2/3 and 3/3 Peter Rosin (3): dt-bindings: display: bridge: lvds-transmitter: add ti,ds90c185 dt-bindings: display: atmel: optional video-interface of endpoints drm/atmel-hlcdc: support bus-width (12/16/18/24) in endpoint nodes .../devicetree/bindings/display/atmel/hlcdc-dc.txt | 28 +++++++++ .../bindings/display/bridge/lvds-transmitter.txt | 8 ++- drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_crtc.c | 70 +++++++++++++++------- drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.h | 1 + drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_output.c | 70 +++++++++++++++++++--- 5 files changed, 149 insertions(+), 28 deletions(-) -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
