[PATCH 0/7] arm64: dts: ti: McASP fixes

Posted by Jai Luthra 1 year, 8 months ago

Drop McASP AFIFOs for all AM62 based platforms, as the extra buffering
is not needed with BCDMA already having internal buffering.

Also fix the pinmux for McASP1 on AM62P.

Is this related with the issue in which after play/record or use the
McASP interface the system crashes or behaves in unexpected ways or this
is something else?

This series does not address that issue. This is for general latency 
improvements.

The fix for that is in the DMA driver. We have something working and 
well tested now in the evil vendor tree, will be posting that to 
dmaengine@ in a few days.
