Subject: [PATCH v4 0/2] spi: omap2-mcspi: Add support for GPIO chipselects
Date: Thu, 7 May 2015 18:36:52 -0500 [thread overview]
Message-ID: <1431041814-24757-1-git-send-email-mwelling@ieee.org> (raw)
This patch allows for GPIOs specified in the devicetree to be used as SPI
chipselects on TI OMAP2 SoCs.
Tested on the AM3354.
v4: Breaks patch down into patch series.
v3: Switches driver to use transfer_one instead of transfer_one_message
allowing the spi core to handle toggling GPIO chip selects if specified.
v2: Considers the possible use of SPI_CS_HIGH during chip select activation.
Michael Welling (2):
spi: omap2-mcspi: Switch driver to use transfer_one
spi: omap2-mcspi: Add gpio_request and init CS
