The backup battery 1362306a36Sopenharmony_ci can be chargeable or non-chargeable. This flag will tells whether 1462306a36Sopenharmony_ci battery is chargeable or not. If charging battery then driver can 1562306a36Sopenharmony_ci enable the charging. 1662306a36Sopenharmony_ci- ti,backup-battery-charge-high-current: Enable high current charging in 1762306a36Sopenharmony_ci backup battery. Device supports the < 100uA and > 100uA charging. 1862306a36Sopenharmony_ci The high current will be > 100uA. Absence of this property will 1962306a36Sopenharmony_ci charge battery to lower current i.e. < 100uA. 2062306a36Sopenharmony_ci 2162306a36Sopenharmony_ciExample: 2262306a36Sopenharmony_ci palmas: tps65913@58 { 2362306a36Sopenharmony_ci ... 2462306a36Sopenharmony_ci palmas_rtc: rtc { 2562306a36Sopenharmony_ci compatible = "ti,palmas-rtc"; 2662306a36Sopenharmony_ci interrupt-parent = <&palmas>; 2762306a36Sopenharmony_ci interrupts = <8 0>; 2862306a36Sopenharmony_ci ti,backup-battery-chargeable; 2962306a36Sopenharmony_ci ti,backup-battery-charge-high-current; 3062306a36Sopenharmony_ci }; 3162306a36Sopenharmony_ci ... 3262306a36Sopenharmony_ci }; 33
