From aa7df40721e36bcf9d4f1a60b9e58e69c08aac48 Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Mon, 3 Aug 2009 21:52:59 -0400 Subject: cx88: Disable xc3028 power management for Geniatech x8000 From: Devin Heitmueller A user discovered that the Geniatech x8000 encountered a regression when the xc3028 power management was introduced. The xc3028 never recovers after setting the powerdown register, which is probably because the xc3028 reset GPIO is not properly configured. Since I do not have access to the hardware and thus cannot determine the correct GPIO configuration, just disable xc3028 power management on this board, which fixes the regression. Thanks to user "ritec" for reporting the issue and testing the fix.
