From: David Brownell Date: Wed, 18 Jun 2008 09:31:43 +0000 (-0700) Subject: at32ap700x spi: enable pullups on MISO X-Git-Tag: v2.6.27-rc1~1108^2~21 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9c2baf785e90419d6f9af6bd07aa0694020cba8d;p=pandora-kernel.git at32ap700x spi: enable pullups on MISO This is a minor tweak to the at32ap700x pin configuration for the SPI input pin (MISO), enabling the on-chip weak pullup (typical 190K) to (a) ensure a fixed data value for missing or input-only slaves; (b) prevent power waste associated with inputs floating near VDDIO/2. Atmel's boards have no external pullup or pulldown on these pins, so it's unlikely other boards would address these issues with external pulldowns. Were there trouble, board-specific code could turn off the relevant pullup(s). Signed-off-by: David Brownell Signed-off-by: Haavard Skinnemoen --- Reading git-diff-tree failed
