Subject: [PATCH 0/2] Add support for sun4i HDMI audio
Date: Fri, 10 Jan 2020 16:11:38 +0200 [thread overview]
Message-ID: <20200110141140.28527-1-stefan@olimex.com> (raw)
This patch series add support for HDMI audio for sun4i HDMI encored.
The code uses some parts from the Allwinners's BSP kernel.
Currently cyclic DMA transfers are disabled. The first patch permits them
as they are required for the audio.
The patch is tested on A20 chip. For the other chips, only the addresses
of the registers are checked.
