- in which case, setting this will harmlessly fail. The property
- 'qcom,fast-charge-current-limit' will be clamped by this value.
-
-- qcom,auto-recharge-threshold-voltage:
- Usage: optional (default: 4.1V, or pre-configured value)
- Value type: <u32>; uV; range [3.24V : 5V]
- Description: Battery voltage limit below which auto-recharge functionality
- will restart charging after end-of-charge; The high cutoff
- limit for auto-recharge is 5% above this value.
-
-- qcom,minimum-input-voltage:
- Usage: optional (default: 4.3V, or pre-configured value)
- Value type: <u32>; uV; range [4.2V : 9.6V]
- Description: Input voltage level above which charging may operate
-
-- qcom,dc-current-limit:
- Usage: optional (default: 100mA, or pre-configured value)
- Value type: <u32>; uA; range [100mA : 2.5A]
- Description: Default DC charge current limit
-
-- qcom,disable-dc:
- Usage: optional (default: false)
- Value type: boolean: <u32> or <empty>
- Description: Disable DC charger
-
-- qcom,jeita-extended-temp-range:
- Usage: optional (default: false)
- Value type: boolean: <u32> or <empty>
- Description: Enable JEITA extended temperature range; This does *not*
- adjust the maximum charge voltage or current in the extended
- temperature range. It only allows charging when the battery
- is in the extended temperature range. Voltage/current
- regulation must be done externally to fully comply with
- the JEITA safety guidelines if this flag is set.

-* QNAP Power Off
-
-QNAP NAS devices have a microcontroller controlling the main power
-supply. This microcontroller is connected to UART1 of the Kirkwood and
-Orion5x SoCs. Sending the character 'A', at 19200 baud, tells the
-microcontroller to turn the power off. This driver adds a handler to
-pm_power_off which is called to turn the power off.
-
-Synology NAS devices use a similar scheme, but a different baud rate,
-9600, and a different character, '1'.
-
-Required Properties:
-- compatible: Should be "qnap,power-off" or "synology,power-off"
-
-- reg: Address and length of the register set for UART1
-- clocks: tclk clock
+++ /dev/null
-* Restart Power Off
-
-Buffalo Linkstation LS-XHL and LS-CHLv2, and other devices power off
-by restarting and letting u-boot keep hold of the machine until the
-user presses a button.
-
-Required Properties:
-- compatible: Should be "restart-poweroff"

-SBS sbs-battery
-~~~~~~~~~~
-
-Required properties :
- - compatible : "sbs,sbs-battery"
-
-Optional properties :
- - sbs,i2c-retry-count : The number of times to retry i2c transactions on i2c
- IO failure.

- after an external change notification.
- - sbs,battery-detect-gpios : The gpio which signals battery detection and
- a flag specifying its polarity.

-TI BQ24735 Charge Controller
-~~~~~~~~~~
-
-Required properties :
- - compatible : "ti,bq24735"
-
-Optional properties :
- - interrupts : Specify the interrupt to be used to trigger when the AC
- adapter is either plugged in or removed.

- presence. This is a Host GPIO that is configured as an input and
- connected to the bq24735.
- - ti,charge-current : Used to control and set the charging current. This value
- must be between 128mA and 8.128A with a 64mA step resolution. The POR value
- is 0x0000h. This number is in mA (e.g. 8192), see spec for more information
- about the ChargeCurrent (0x14h) register.
- - ti,charge-voltage : Used to control and set the charging voltage. This value
- must be between 1.024V and 19.2V with a 16mV step resolution. The POR value
- is 0x0000h. This number is in mV (e.g. 19200), see spec for more information
- about the ChargeVoltage (0x15h) register.
- - ti,input-current : Used to control and set the charger input current. This
- value must be between 128mA and 8.064A with a 128mA step resolution. The
- POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
- more information about the InputCurrent (0x3fh) register.
- - ti,external-control : Indicates that the charger is configured externally
- and that the host should not attempt to enable/disable charging or set the
- charge voltage/current.

-
- bq24735@9 {
- compatible = "ti,bq24735";
