[PATCH 0/2] dmaengine: ti: k3-udma: Get supported throughput levels from hardware

Peter Ujfalusi <peter.ujfalusi@xxxxxx> · Fri, 17 Jul 2020 15:09:01 +0300

Hi,

Newer versions of UDMAP have information on the number of different throughput
channels in it's CAP registers.

The driver can auto configure based on the information from the hardware isntead
a table within the match_data.

With this change we can use the same compatible string for identical versions of
UDMAP when only the number of UHCHAN and HCHAN is different.

Regards,
Peter
