Subject: gxt4500: enable panning
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2035608e126f4ddc6a48f6b04ef967f89db460e1;p=linux-beck.git

gxt4500: enable panning

The driver implements pan_display but the corresponding flags are not set.

Add FBINFO_HWACCEL_XPAN and FBINFO_HWACCEL_YPAN to flags to allow HW
accelerated panning (for fast scrolling).
