From 3fba19ec1ae5b460c73a7f32efed8d3b3300b246 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 8 Nov 2008 01:13:16 +0100 Subject: [PATCH] mfd: allow reading entire register banks on twl4030 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.
