Subject: [PATCH 0/2] mux: adg2404: add support for ADG2404 multiplexer

This series adds support for the Analog Devices ADG2404, a 4:1 analog
multiplexer with low 0.62Ω on-resistance.

The ADG2404 features:
- Low RON of 0.62Ω
- Flat RON across signal range (0.003Ω)
- Dual supply operation (±15V, ±5V)
- Single supply operation (+12V)
- Asymmetric supply support (+5V/-12V)
- 1.8V/3.3V/5V logic compatibility
- Break-before-make switching

Applications include automatic test equipment, data acquisition,
instrumentation, audio/video switching, and communication systems.
