Subject: [PATCH 0/2] dmaengine: ti: k3-udma: Get supported throughput levels from hardware
Date: Fri, 17 Jul 2020 15:09:01 +0300
Message-ID: <20200717120903.8774-1-peter.ujfalusi@ti.com> (raw)

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
