[alsa-devel] [PATCH 05/14] mfd: sun6i-prcm: Add sun8i analog codec as subnode

Mylène Josserand mylene.josserand at free-electrons.com
Tue Oct 4 11:46:18 CEST 2016


The sun8i audio codec is using PRCM registers to configure all the
analog part of the audio codec. It is added as a subnode of the PRCM
with his resource (offset of 0x1c0).
