43   qcom,fast-charge-current-limit:
49   qcom,fast-charge-low-threshold-voltage:
54       Battery voltage limit in uV above which fast charging may operate; Defaults to 3.2V
55       Below this value linear or switch-mode auto-trickle-charging will operate.
57   qcom,fast-charge-high-threshold-voltage:
62       Battery voltage limit in uV below which fast charging may operate; Defaults to 4.2V
66   qcom,fast-charge-safe-voltage:
71       Maximum safe battery voltage in uV; May be pre-set by bootloader, in which case,
72       setting this will harmlessly fail. The property 'fast-charge-high-watermark' will
75   qcom,fast-charge-safe-current:
80       Maximum safe battery charge current in uA; May pre-set by bootloader, in which case,
81       setting this will harmlessly fail. The property 'qcom,fast-charge-current-limit'
84   qcom,auto-recharge-threshold-voltage:
89       Battery voltage limit in uV below which auto-recharge functionality will restart charging
90       after end-of-charge; The high cutoff limit for auto-recharge is 5% above this value.
93   qcom,minimum-input-voltage:
98       Input voltage level in uV above which charging may operate. Defaults to 4.3V.
100   qcom,dc-current-limit:
107   qcom,disable-dc:
111   qcom,jeita-extended-temp-range:
114       Enable JEITA extended temperature range;  This does *not* adjust the maximum charge
115       voltage or current in the extended temperature range. It only allows charging when

130   otg-vbus:
134       Specifically whether to supply voltage to VBUS for host mode operation of the OTG port,
135       or allow input voltage from external VBUS for charging. In the hardware, the supply for
136       this regulator comes from usb_otg_in-supply.
