Kconfig warnings: (for reference only)
WARNING: unmet direct dependencies detected for REGMAP_SPI
Depends on [n]: SPI [=n]
Selected by [y]:
- AD9739A [=y] && IIO [=y] && (SPI [=n] || COMPILE_TEST [=y])
The issue is caused by CONFIG_AD9739A=y when CONFIG_SPI is not set.
Add explicit dependency on SPI and conditional selection of REGMAP_SPI.
Fixes: e77603d5468b ("iio: dac: support the ad9739a RF DAC")
