The backup battery 14666a584dSLaxman Dewangan can be chargeable or non-chargeable. This flag will tells whether 15666a584dSLaxman Dewangan battery is chargeable or not. If charging battery then driver can 16666a584dSLaxman Dewangan enable the charging. 17666a584dSLaxman Dewangan- ti,backup-battery-charge-high-current: Enable high current charging in 183b567271SDr. H. Nikolaus Schaller backup battery. Device supports the < 100uA and > 100uA charging. 193b567271SDr. H. Nikolaus Schaller The high current will be > 100uA. Absence of this property will 203b567271SDr. H. Nikolaus Schaller charge battery to lower current i.e. < 100uA. 21666a584dSLaxman Dewangan 22666a584dSLaxman DewanganExample: 23666a584dSLaxman Dewangan palmas: tps65913@58 { 24666a584dSLaxman Dewangan ... 25666a584dSLaxman Dewangan palmas_rtc: rtc { 26666a584dSLaxman Dewangan compatible = "ti,palmas-rtc"; 27666a584dSLaxman Dewangan interrupt-parent = <&palmas>; 28666a584dSLaxman Dewangan interrupts = <8 0>; 29666a584dSLaxman Dewangan ti,backup-battery-chargeable; 30666a584dSLaxman Dewangan ti,backup-battery-charge-high-current; 31666a584dSLaxman Dewangan }; 32666a584dSLaxman Dewangan ... 33666a584dSLaxman Dewangan }; 34
