Subject: pxa2xx_spi: fix for SPI_CS_HIGH
X-Git-Tag: v2.6.31-rc1~264
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=50e0a7bd02f95be95ac03299b0356ba6400d1c6d;p=platform%2Fkernel%2Flinux-3.10.git

pxa2xx_spi: fix for SPI_CS_HIGH

Commit a7bb3909b3293d503211d7f6af8ed62c1644b686 ("spi: pxa2xx_spi:
introduce chipselect GPIO to simplify the common cases") introduces
chipselect GPIO, and configures the CS polarity using SPI_CS_HIGH
spi->mode flag.  Add SPI_CS_HIGH to the allowed modes.
