From dfc721864dcc1d0a8447474be84ed3db2c9fa70c Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Tue, 20 Jun 2023 16:22:21 +0530 Subject: dma: ti: k3-udma: Add support for native configuration of chan/flow In absence of Device Manager (DM) services such as at R5 SPL stage, driver will have to natively setup TCHAN/RCHAN/RFLOW cfg registers. Existing UDMA driver performed the above mentioned configuration for UDMA. Add similar configuration for PKTDMA here.
