+### pmic-init
+Reinitializes the PMIC driver, restoring it to its default state.
+
+Example:
+```
+# Initializing the NPM1300 driver...
+OK
+```
+
+### pmic-charge-enable
+Enables battery charging. If a charger is connected, charging starts immediately.
+
+Example:
+```
+pmic-charge-enable
+# Enabling battery charging @ 180mA...
+OK
+```
+
+### pmic-charge-disable
+Disables battery charging.
+
+Example:
+```
+pmic-charge-disable
+# Disabling battery charging...
+OK
+```
+
+### pmic-charge-set-limit
+Sets the batter charging current limit.
+
+`pmic-charge-set-limit <limit>`
+
+* `limit` - Charging limit in mA, ranging from 30 to 180.
+
+```
+pmic-charge-set-limit 100
+# Setting battery charging limit to 100 mA...
+OK

+
+### pmic-buck-set-mode
+Selects of one PMIC buck converter modes.
+
+`pmic-buck-set-mode <mode>`
+
+* `pmic-buck-set-mode` - Buck converter mode (pwm, pfm or auto)
+
+Example:
+```
+pmic-buck-set-mode auto
+# Setting the buck converter mode...
+OK
+```
+
+### pmic-report
+Starts single or continuous reporting of PMIC state including voltage, current and temperature.
+
+`pmic-report [<count>] [<period>]`
+
+* `count` - Number of measurement periods
+* `period` - Duration of single measurement period in milliseconds
+
+Example:
+```
+pmic-report 4 1000
+#       time      vbat  ibat  ntc    vsys  die    bat  buck mode

+### wpc-init
+Reinitializes the wireless power receiver driver, restoring it to its default state.
+
+Example:
+```
+wpc-init
+# Initializing the WPC driver...

+```
+
+### wpc-enable
+Enables the wireless power receiver. When enabled, the receiver can initiate communication with the transmitter. To start battery charging, the voltage output must also be enabled (see `wpc-out-enable`).
+
+Example:
+```
+wpc-enable
+# Enabling STWLC38...
+OK
+```
+
+### wpc-disable
+Disables wireless power receiver.
+
+Example:
+```
+wpc-disable
+# Disabling STWLC38...
+OK
+```
+
+### wpc-out-enable
+Enables the voltage output of the wireless power receiver.  By default, the voltage output is enabled.
+
+Example:
+```
+wpc-out-enable
+# Enabling STWLC38 output...
+OK
+```
+
+### wpc-out-disable
+Disables the voltage output of the wireless power receiver.
