Subject: [PATCH 00/11] ARM: DTS/clk: DRA7 family: enable eDMA and audio updates
Date: Thu, 25 Feb 2016 16:50:16 +0200 [thread overview]
Message-ID: <1456411827-23962-1-git-send-email-peter.ujfalusi@ti.com> (raw)
Hi,
On dra7 family we have two DMA engine available: sDMA (omap-dma) and eDMA.
For some peripherals the use of eDMA is better due to L3 interconnect limitation
when using sDMA. Such peripherals are McASP1/2/3. By switching to eDMA we can
enable the AFIFO which will help to avoid under or overruns in audio.
This set will:
- add the hwmod data for eDMA TPCC and TPTCs
- add the needed DT nodes for eDMA and the crossbar
- we will enable the AFIFO use for audio
- add hwmod data and DT nodes for all McASP ports
- Fix the beagle-x15's clkout2 parent setting for the codec
The patch set has been tested on top of linux-next.
Regards,
Peter
