Date: Tue, 10 Sep 2013 13:10:22 -0400 From: Ben Gardiner <ben.l.gardiner@...il.com> To: grant.likely@...retlab.ca, spi-devel-general@...ts.sourceforge.net, davinci-linux-open-source@...ux.davincidsp.com Cc: linux-kernel@...r.kernel.org Subject: [PATCH] spi: spi-davinci: deassert CS on setup() The mmc_spi driver's mmc_cs_off() function states that "chipselect will always be inactive after setup()"; however, the spi-davinci driver's setup() leaves CS state unchanged. Add a call to davinci_spi_chipselect(spi, BITBANG_CS_INACTIVE) to the spi- davinci drivers' setup() function.
