From: David Brownell Date: Fri, 7 Nov 2008 22:00:03 +0000 (-0800) Subject: twl4030-core: allow reading entire register banks X-Git-Tag: v2.6.28-omap1~166 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f08b1f969bfd892e99d95ffc402aeb3b2c8515a6;p=linux-2.6-omap-h63xx.git twl4030-core: allow reading entire register banks Minor change to the TWL4030 utility interface: support reads of all 256 bytes in each register bank (vs just 255). This can help when debugging, but is otherwise a NOP.
