drm/vc4: Fix oops dereferencing DPI's connector since panel_bridge.

2018-05-07T14:19:11Z

In the cleanup, I didn't notice that we needed to dereference the connector for the bus_format. Fix the regression by looking up the first (and only) connector attached to us, and assume that its bus_format is what we want. Some day it would be good to have that part of display_info attached to the bridge, instead. v2: Fix stray whitespace change Signed-off-by: Eric Anholt Fixes: 7b1298e05310 ("drm/vc4: Switch DPI to using the panel-bridge helper.")

drm/vc4: remove bridge from driver internal structure

2017-10-10T09:32:54Z

With a call to drm_of_panel_bridge_remove() we could remove the bridge without store it in vc4_dpi internal driver structure. Signed-off-by: Benjamin Gaignard Reviewed-by: Eric Anholt Link: https://patchwork.freedesktop.org/patch/msgid/1506936888-23844-5-git-send-email-benjamin.gaignard@linaro.org

drm: vc4: Use crtc->mode_valid() and encoder->mode_valid() callbacks

2017-06-20T08:46:36Z

Now that we have a callback to check if crtc and encoder supports a given mode we can use it in vc4 so that we restrict the number of probed modes to the ones we can actually display. Also, remove the mode_fixup() calls as these are no longer needed because mode_valid() will be called before.

drm/vc4: fix include notation and remove -Iinclude/drm flag

drm: convert drivers to use of_graph_get_remote_node

2017-04-06T21:00:27Z

Convert drivers to use the new of_graph_get_remote_node() helper instead of parsing the endpoint node and then getting the remote device node. Now drivers can just specify the device node and which port/endpoint and get back the connected remote device node. The details of the graph binding are nicely abstracted into the core OF graph code. This changes some error messages to debug messages (in the graph core). Graph connections are often "no connects" depending on the particular board, so we want to avoid spurious messages. Plus the kernel is not a DT validator.

drm/vc4: Extend and edit documentation for output from the RST

2017-02-28T20:51:49Z

I had written most of my comments as if I was describing the individual code files the way I used to for doxygen, while for RST we want to describe things in a more chapter/section way where there's no obvious relation to .c files. Additionally, several of the files had stub descriptions that I've taken this opportunity to extend.

Unlike the other encoders in the driver, I've also dropped the debug dump function. There's only really one register to this device, and we have the debugfs reg entry still.
