This looks like it's a device which maps a shared DMA controller in the SoC core into ASoC rather than actual hardware. Such devices are usually instantiated automatically from the DAI rather than being represented in the device tree since they are a Linux internal thing really - the Tegra and Freescale drivers provide examples of how this sort of thing can be done. --bp/iNruPH9dso1Pn Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAEBAgAGBQJQLsYvAAoJEFJkBDiqVpZ4sS4QALMO1nb9g20kTiJ6ZjWQCGYX jYtzMvLM1OoNdNUwpzCZ4vi5vxbx+Td//Py59sKwKA3IXcHw+MSCyC+G7NYTle58 Ot170pSO2xU068GEZWFigLEOw8f/SPzJkA/3sttfdF3Px/GuyL/uo7sKVPAtitGC X1jdiiCn2BcJu6UUoM7+T6tJm2Vy8aHF4e4bDbd0VX045coO/FFuviffLeGoewT5 0gSaVnTEFKCiBNumiqwIL+LiuWT+7V/CV7exvnfB1oaBABBIt1roSOHZcO3M5KZS TSx4wazOLyyx6LjSqBK+Oz5DZf7CzF6dgpu4yznaMO8iDcGBG59wxlq5Q1XUVf7S dZxUDylUS18R+/hrzCLE7BdjaIlZrdL9jppukKY3ftL/lHsxKB4eVVgS5h7IChDo J9XLEyrveIhWeb8VjJPsszLNuSphXySZwO3o0vbmJ/dbgcBClN6ZSkygofCfL36V RrLKJZP0xm6C+aMBym9homd6M4k/GHx35FIPocsxd3MWe9y9uSliHjhdOhCLY/xP yGpSF2D834PIeo4bhv1nrbJGzaciaKcm4K+G8xFwR1y2bkdV1C2OyI5ZhJz5nL0K VkcuX94TItpuJQithe1raHbDG3ZlvrgYn5x9y5b4hslJUfHA35eWfCpBK6lMJ+z7 U35Uqnx8LLs9hrpuf32Q =Ap4d -----END PGP SIGNATURE----- --bp/iNruPH9dso1Pn-- --===============3150895413801385594== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline --===============3150895413801385594==--
