Subject: [PATCH] spi: spi-fsl-dspi: add SPI_LSB_FIRST to driver capabilities
Date:   Mon, 13 Nov 2017 08:47:21 +0100
Message-Id: <20171113074721.22404-1-kurt@linutronix.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The driver as well as the controller support the SPI lsb first
mode. However, it's not possible to configure it e.g. when using
spidev. Adding this flag to mode_bits resolves the issue and lsb first
mode can be used.
