Subject: [PATCH v3 2/2] spi: pxa2xx: Debug print DMA burst size
Date: Mon, 18 Mar 2019 16:41:44 +0200	[thread overview]
Message-ID: <20190318144144.42367-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20190318144144.42367-1-andriy.shevchenko@linux.intel.com>

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