From 372f8b3621294173f539b32976e41e6e12f5decf Mon Sep 17 00:00:00 2001 From: Vignesh Raghavendra Date: Fri, 7 Jun 2024 23:41:03 +0530 Subject: [PATCH] dmaengine: ti: k3-udma: Fix BCHAN count with UHC and HC channels Unlike other channel counts in CAPx registers, BCDMA BCHAN CNT doesn't include UHC and HC BC channels. So include them explicitly to arrive at total BC channel in the instance.
