Subject: [PATCH v6 0/2] iio: amplifiers: add support for ADL8113 Low Noise Amplifier

This patch series adds support for the Analog Devices ADL8113, a 10MHz to 12GHz
Low Noise Amplifier with integrated bypass switches.

The ADL8113 provides four operation modes controlled by two GPIO pins:
- Internal Amplifier (14dB gain)
- Internal Bypass (-2dB insertion loss)
- External Bypass A (configurable gain) - Signal routes from RFIN to OUT_A and from IN_A to RFOUT
- External Bypass B (configurable gain) - Signal routes from RFIN to OUT_B and from IN_B to RFOUT

The driver allows selecting between these paths via the IIO hardwaregain attribute,
with optional external amplifier gains configured through device tree properties.
