Subject: [PATCH 0/2] ASoC: rsnd: Fixes for multichannel HDMI audio output
Date: Wed, 15 Apr 2020 16:10:15 +0200 [thread overview]
Message-ID: <20200415141017.384017-1-matthias.blankertz@cetitec.com> (raw)
This fixes two issues in the snd-soc-rcar driver blocking multichannel
HDMI audio out: The parent SSI in a multi-SSI configuration is not
correctly set up and started, and the SSI->HDMI channel mapping is
wrong.
With these patches, the following device tree snippet can be used on an
r8a7795-based platform (Salvator-X) to enable multichannel HDMI audio on
HDMI0:
rsnd_port1: port@1 {
rsnd_endpoint1: endpoint {
remote-endpoint = <&dw_hdmi0_snd_in>;
dai-format = "i2s";
bitclock-master = <&rsnd_endpoint1>;
frame-master = <&rsnd_endpoint1>;
playback = <&ssi0 &ssi1 &ssi2 &ssi9>;
};
};
With a capable receiver attached, all of 2ch (stereo), 6ch (e.g. 5.1)
and 8ch audio output should work.
