Subject: [PATCH v5 4/4] spi: spidev_test Add three missing spi mode bits
Date:   Sat, 20 May 2023 21:08:55 +0200
Message-Id: <20230520190856.34720-5-boerge.struempfel@gmail.com>
In-Reply-To: <20230520190856.34720-1-boerge.struempfel@gmail.com>
References: <20230520190856.34720-1-boerge.struempfel@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Precedence: bulk

Added the three missing spi mode bits SPI_3WIRE_HIZ, SPI_RX_CPHA_FLIP,
and SPI_MOSI_IDLE_LOW. Due to the length of the new options, the
indentation of the options in the help message was also adjusted for all
other options.
