Date: Mon, 11 Feb 2013 15:55:39 +0100 From: "Jens Renner (EFE)" <renner@...-gmbh.de> To: spi-devel-general@...ts.sourceforge.net CC: linux-kernel@...r.kernel.org Subject: [PATCH] spi: spi-xilinx: Use DT information for bits_per_word value From: Jens Renner <renner@...-gmbh.de> This patch overrides the default value of bits_per_word with the actual value of "xlnx,num-transfer-bits" from the DTS file to allow for 16 and 32 bit word lengths.
