drm: convert drivers to use of_graph_get_remote_node

2017-04-06T21:00:27+00:00

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: Add acquire ctx to ->gamma_set hook

2017-04-06T08:21:55+00:00

Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.

drm: vc4: remove redundant check of plane being non-null

2017-03-17T23:44:14+00:00

The pointer plane is always null on the error path at label 'fail' hence the check if it is non-null is redundant. We can therefore remove the check and the destruction of plane as well as the fail error path and instead just return an -ENOMEM ERR_PTR.

drm/vc4: Add HDMI audio support

2017-03-16T17:33:30+00:00

The HDMI encoder IP embeds all needed blocks to output audio, with a custom DAI called MAI moving audio between the two parts of the HDMI core. This driver now exposes a sound card to let users stream audio to their display. Using the hdmi-codec driver has been considered here, but MAI meant having to significantly rework hdmi-codec, and it would have left little shared code with the I2S mode anyway. The encoder requires that the audio be SPDIF-formatted frames only, which alsalib will format-convert for us. This patch is the combined work of Eric Anholt (initial register setup with a separate dmaengine driver and using simple-audio-card) and Boris Brezillon (moving it all into HDMI, massive debug to get it actually working), and which Eric has the permission to release. v2: Drop "-audio" from sound card name, since that's already implied (suggestion by Boris) Signed-off-by: Eric Anholt Acked-by: Boris Brezillon Link: http://patchwork.freedesktop.org/patch/msgid/20170227202803.12855-2-eric@anholt.net
