Optional subnodes:

The sub-functions of CPCAP get their own node with their own compatible values,
which are described in the following files:

- ../power/supply/cpcap-battery.txt
- ../power/supply/cpcap-charger.txt
- ../regulator/cpcap-regulator.txt
- ../phy/phy-cpcap-usb.txt
- ../input/cpcap-pwrbutton.txt
- ../rtc/cpcap-rtc.txt
- ../leds/leds-cpcap.txt
- ../iio/adc/cpcap-adc.txt

The only exception is the audio codec. Instead of a compatible value its
node must be named "audio-codec".

Required properties for the audio-codec subnode:

- #sound-dai-cells = <1>;

The audio-codec provides two DAIs. The first one is connected to the
Stereo HiFi DAC and the second one is connected to the Voice DAC.
