+Subject: [PATCH] introduce-bq27000-battery-driver.patch
+
+This is a driver for the bq27000 found in the Highcell A5
+battery, and the platform device stuff for it for GTA02. It
+is a Power Supply Class battery device.
+
+The driver doesn't contain an HDQ engine but accepts pointers
+from the platform data to the HDQ action routines; our
+platform data plugs it into the FIQ HDQ engine stuff.
+
+The Power Supply class exposes the battery down /sys so you
+can find out battery status by doing the equivalent of this
+bash command
+
+for i in capacity charge_full current_now present status technology temp time_to_empty_now time_to_full_now type voltage_now ; do echo -n "$i " ; cat /sys/devices/platform/bq27000-battery.0/power_supply/bat/$i ; done
+
+Here is the kind of result you get from a battery discharging
+
+capacity 0
+charge_full 1215585
+current_now 183375
+present 1
+status Discharging
+technology Li-ion
+temp 276
+time_to_empty_now 0
+time_to_full_now 3932100
+type Battery
+voltage_now 2761000
+
+Note that temp is in 1/10 degrees C, other values are in uV,
+uA, uW. The time_to_* reported are bogus, but that is what
+the battery actually reports.
+
+We can make more mappings to entries in power_supply class
+but this is enough to get started with.
