Subject: [PATCH 27/30] dma/dpaa: improve silent mode support
Date: Fri, 19 Jul 2024 15:31:23 +0530	[thread overview]
Message-ID: <20240719100126.1150373-27-g.singh@nxp.com> (raw)
In-Reply-To: <20240719100126.1150373-1-g.singh@nxp.com>

From: Jun Yang <jun.yang@nxp.com>

Don't save eq context in silent mode, check HW status only to
identify if queue is full.
