The backup battery 13*c66ec88fSEmmanuel Vadot can be chargeable or non-chargeable. This flag will tells whether 14*c66ec88fSEmmanuel Vadot battery is chargeable or not. If charging battery then driver can 15*c66ec88fSEmmanuel Vadot enable the charging. 16*c66ec88fSEmmanuel Vadot- ti,backup-battery-charge-high-current: Enable high current charging in 17*c66ec88fSEmmanuel Vadot backup battery. Device supports the < 100uA and > 100uA charging. 18*c66ec88fSEmmanuel Vadot The high current will be > 100uA. Absence of this property will 19*c66ec88fSEmmanuel Vadot charge battery to lower current i.e. < 100uA. 20*c66ec88fSEmmanuel Vadot 21*c66ec88fSEmmanuel VadotExample: 22*c66ec88fSEmmanuel Vadot palmas: tps65913@58 { 23*c66ec88fSEmmanuel Vadot ... 24*c66ec88fSEmmanuel Vadot palmas_rtc: rtc { 25*c66ec88fSEmmanuel Vadot compatible = "ti,palmas-rtc"; 26*c66ec88fSEmmanuel Vadot interrupt-parent = <&palmas>; 27*c66ec88fSEmmanuel Vadot interrupts = <8 0>; 28*c66ec88fSEmmanuel Vadot ti,backup-battery-chargeable; 29*c66ec88fSEmmanuel Vadot ti,backup-battery-charge-high-current; 30*c66ec88fSEmmanuel Vadot }; 31*c66ec88fSEmmanuel Vadot ... 32*c66ec88fSEmmanuel Vadot }; 33
