ASoC: meson: axg-frddr: add g12a support On the axg, frddr could only be connected to 1 downstream element, so the playback was possible on 1 interface only at a time. On the g12a, the frddr may connect and wait for the request of up to 3 downstream elements. With this, it possible for single playback to be played on several interfaces at the same time. Like the toddr fifo, the g12a frddr also need to take care of resetting the read pointer to the initial fifo address when preparing a playback.

ASoC: meson: axg-frddr: add g12a support On the axg, frddr could only be connected to 1 downstream element, so the playback was possible on 1 interface only at a time. On the g12a, the frddr may connect and wait for the request of up to 3 downstream elements. With this, it possible for single playback to be played on several interfaces at the same time. Like the toddr fifo, the g12a frddr also need to take care of resetting the read pointer to the initial fifo address when preparing a playback.

MODULE_DESCRIPTION("Amlogic AXG/G12A playback fifo driver");
ASoC: meson: add axg frddr driver Add the playback memory interface of Amlogic's axg SoCs. This device pulls data from DDR to an internal FIFO. This FIFO is then used to feed TDM and SPDIF Output devices. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Mark Brown <broonie@kernel.org>
