Subject: [PATCH] ARM: OMAP: Input: ads7846: select correct SPI mode
X-Git-Tag: v2.6.17-omap1~44
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=17bd6d0083f28b12bc3c0de812721563d09cc996;p=linux-2.6-omap-h63xx.git

[PATCH] ARM: OMAP: Input: ads7846: select correct SPI mode

The device is using a protocoll where writes are on the falling, reads are
on the rising edge of the clock. This maps to SPI mode 1.
