From 6211ae13c3f366c0121a3b195196607f80cf29d3 Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Sat, 12 Jan 2008 22:29:17 +0000 Subject: Fix the documentation of GPIO setup, tell W83627EHF to use external suspend clock (undocumented in datasheet, documented in 'W83627HG-AW'). Introduce sio_init function for all this. Signed-off-by: Rudolf Marek Acked-by: Ronald G.
