+Subject: [PATCH] introduce-usb-host-power-control.patch
+
+Unless I really really missed the point, there is no support for enabling
+USB Host power for USB host mode.  This patch adds a /sys node for GTA02
+that allows control of the charge pump for 5V out on the USB mini connector
+It doesn't change any logical mode in the CPU, just enables (1) and disables
+(0) USB host power.
