Subject: [PATCH v4 1/2] spi: pxa2xx: Debug print DMA burst size
Date: Tue, 19 Mar 2019 16:43:51 +0200	[thread overview]
Message-ID: <20190319144352.2293-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20190319144352.2293-1-andriy.shevchenko@linux.intel.com>

It's useful during debug to see what DMA burst size is.
