Subject: [PATCH v2 2/2] spi: dw-mid: fix number of CS lines
Date: Fri, 2 Jan 2015 17:48:52 +0200 [thread overview]
Message-ID: <1420213732-5141-2-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1420213732-5141-1-git-send-email-andriy.shevchenko-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>
According to specification the SPI1 has 5 bits for chip selects. The current
code limits it to 4 bits. The patch fixes that constant.
Fixes: 7063c0d942a1 (spi/dw_spi: add DMA support)
