| |
The X-Powers AXP20X and AXP22X PMICs have multiple ADCs. They expose the battery voltage, battery charge and discharge currents, AC-in and VBUS voltages and currents, 2 GPIOs muxable in ADC mode and PMIC temperature.
This adds the device tree binding documentation for the X-Powers AXP20X and AXP22X PMICs ADCs.

v2: - removing io-channels from required properties, - update AXP ADC DT node name from axp209_adc to simply adc,
