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
