Subject: [PATCH v3 01/20] dmaengine: ti: k3-udma: Correct normal channel offset when uchan_cnt is not 0
Date: Tue, 8 Dec 2020 11:04:21 +0200 [thread overview]
Message-ID: <20201208090440.31792-2-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20201208090440.31792-1-peter.ujfalusi@ti.com>
According to different sections of the TRM, the hchan_cnt of CAP3 includes
the number of uchan in UDMA, thus the start offset of the normal channels
are hchan_cnt.
Fixes: daf4ad0499aa4 ("dmaengine: ti: k3-udma: Query throughput level information from hardware")
