Description:    Attribute for enable/disable the trickle charge bypass
		The trickle_charge_bypass attribute allows the userspace to
                enable/disable the Trickle charge FET bypass.
rtc: bq32000: add support to enable disable the trickle charge FET bypass The bq32000 includes a trickle charge circuit to maintain the charge of the backup supply when a super capacitor is used. You can enable the charging circuit by setting 'trickle-resistor-ohms', additionally you can set TCFE to 1 to bypass the internal diode and boost the charge voltage of the backup supply. You might want to enable/disable the TCFE switch from userspace (e.g when device is only connected to a battery) This patch introduces a new sysfs entry to enable and disable this FET form userspace.
