Subject: fix_glamo_xrandr_bug.patch
X-Git-Url: http://git.openmoko.org/?p=kernel.git;a=commitdiff_plain;h=40fe0a30c75937a476ea50220814ca8b1fd81b45
fix_glamo_xrandr_bug.patch
This patch reintroduces the 2-cycle delay used when accessing glamo-fb
registers. This seems to be required even when the corresponding
registers in HOST_BUS are off.
