X-Git-Tag: v2.6.34-rc1~285^2~24 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=92e1f9a7ed613b36f3aaf8b04a79e2fd4fa37ec1;p=pandora-kernel.git video: sh_mobile_lcdcfb: Fix panning. Fixed SH-Mobile panning. Previously the address of the frame to be displayed was updated in the VSync end interrupt. This meant there was a minimum of 1 frame bewteen calling FBIOPAN_DISPLAY ioctl and the pan occuring. This meant that apps were not able to use the FBIO_WAITFORVSYNC ioctl to wait for the pan to complete. This patch moves the write to LDSA1R mirror reg into the pan ioctl. Tested on MS7724 board against 2.6.33-rc7 Signed-off-by: Phil Edworthy Signed-off-by: Paul Mundt --- Reading git-diff-tree failed
