This patch series updates the AD8366 amplifier/attenuator driver with
modern device resource management, including support for additional
device variants.
Adds support for multiple digital step attenuators:
- ADRF5720: 0.5 dB LSB, 6-Bit, Digital Attenuator, 9 kHz to 40 GHz
- ADRF5730: 0.5 dB LSB, 6-Bit, Digital Attenuator, 100 MHz to 40 GHz
- ADRF5731: 2 dB LSB, 4-Bit, Digital Attenuator, 100 MHz to 40 GHz
- HMC271A: 1 dB LSB, 5-bit, Digital Attenuator, 0.7 - 3.7 GHz
- HMC1018A: 1.0 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.1 - 30 GHz
- HMC1019A: 0.5 dB LSB GaAs MMIC 5-BIT DIGITAL ATTENUATOR, 0.1 - 30 GHz
Device Tree Support:
- Adds device tree binding documentation
- Adds device tree compatible strings for all supported devices
- Favor chip info tables over device type.
