This series adds optional enable GPIO support to the gpio-mux driver.
The enable GPIO allows the multiplexer to be disabled before changing
address lines and re-enabled after, preventing glitches that could
briefly activate unintended channels during transitions.

This feature is useful for devices like the Analog Devices ADG2404
(4:1 mux) that require enable control for glitch-free operation. The
binding documentation now includes ADG2404 as a supported device with
a dedicated example.

This version of the patches look good to me!
