10 - ti,backup-battery-chargeable: The Palmas ser 10 - ti,backup-battery-chargeable: The Palmas series device like TPS65913 or
11 TPS80036 supports the backup battery f 11 TPS80036 supports the backup battery for powering the RTC when main
12 battery is removed or in very low powe 12 battery is removed or in very low power state. The backup battery
13 can be chargeable or non-chargeable. T 13 can be chargeable or non-chargeable. This flag will tells whether
14 battery is chargeable or not. If charg 14 battery is chargeable or not. If charging battery then driver can
15 enable the charging. 15 enable the charging.
16 - ti,backup-battery-charge-high-current: Enabl 16 - ti,backup-battery-charge-high-current: Enable high current charging in
17 backup battery. Device supports the < 17 backup battery. Device supports the < 100uA and > 100uA charging.
18 The high current will be > 100uA. Abse 18 The high current will be > 100uA. Absence of this property will
19 charge battery to lower current i.e. < 19 charge battery to lower current i.e. < 100uA.
