From: Jian Xu Date: Wed, 19 Dec 2018 03:19:51 +0000 (+0800) Subject: audio: auge: add HDMIRX SPDIF in support [1/2] X-Git-Tag: hardkernel-4.9.236-104~1987 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b315b2ba0b0bb57e0d12479220b27a2282674536;p=platform%2Fkernel%2Flinux-amlogic.git audio: auge: add HDMIRX SPDIF in support [1/2] PD#SWPL-2956 Problem: HDMI in DTS/Dolby input has noise when treated to LPCM Solution: By default,we are using PAO mode for HDMIRX,but we have not enabled the PaPb search for 61937 raw data input, after add that, we can detect the raw data, but it can not by clear when switch from NONE-LPCM to NONE-LPCM, need add IRQ function to clear that by sw.we enabled spdif in from HDMIRX, which is the same design as txl/txlx.we can get the Pc information now. also we add a new interface to set spdif in source when hdmirx input.
