drm/bridge/sii8620: Fix memory corruption

2017-08-24T17:06:32+00:00

Function sii8620_mt_read_devcap_reg_recv() used to read array index from a wrong msg register, which caused writing out of array bounds. It led to writing on other fields of struct sii8620.

drm/bridge: tc358767: fix probe without attached output node

2017-07-28T03:58:28+00:00

The output node of the TC358767 is only used if another bridge is chained behind it. Panels attached to the TC358767 can be detected using the usual DP AUX probing. This restores the old behavior of ignoring the output if no endpoint is found.

drm: adv7511_audio: Add .get_dai_id callback to map port number to dai id

2017-06-28T20:00:08+00:00

ALSA SoC needs to know connected DAI ID for probing. Using the new audio-card-graph approach, ports/endpoints are used to describe how the links are connected. Unfortunately, since ports/endpoints are used as well for video linkages, there are some issues mixing the port ids to the two (video and audio) namespaces. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops. The will assume that HDMI audio out will be connected to reg = <2>. This will then be remapped to the ALSA SoC side will as DAI 0. Allowing the adv7511's hdmi audio support to be used with the audio-card-graph. Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c was what this was mostly copy-pasted from.

drm: dw-hdmi-i2s: add .get_dai_id callback for ALSA SoC

2017-06-28T19:46:39+00:00

ALSA SoC needs to know connected DAI ID for probing. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops. dw-hdmi-i2s will assume that HDMI sound will be connected to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0 ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; /* HDMI Video IN */ }; port@1 { reg = <1>; /* HDMI OUT */ }; port@2 { reg = <2>; /* HDMI Sound IN */ }; }; Signed-off-by: Kuninori Morimoto Acked-by: Archit Taneja Signed-off-by: Mark Brown
