OK thanks for the report, we need IIO for VBUS level, here's
a patch to fix it.

Subject: [PATCH] phy: cpcap-usb: Fix build by adding a dependency to
CONFIG_IIO
We need the ADC output provided by IIO to detect VBUS level.
Otherwise we can get:
drivers/built-in.o: In function `cpcap_usb_detect':
phy-cpcap-usb.c:(.text+0x18ad): undefined reference to
`iio_read_channel_processed'
drivers/built-in.o: In function `cpcap_usb_phy_probe':
phy-cpcap-usb.c:(.text+0x1c5e): undefined reference to
`devm_iio_channel_get'
phy-cpcap-usb.c:(.text+0x1c92): undefined reference to`iio_get_channel_type'
