Subject: [PATCH v2 2/2] spi: pxa2xx: Debug print DMA burst and threshold
Date: Tue, 26 Feb 2019 14:49:21 +0300	[thread overview]
Message-ID: <20190226114921.48205-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20190226114921.48205-1-andriy.shevchenko@linux.intel.com>

It's useful during debug to see what DMA burst and threshold sizes are.
