to prevent glitches during channel transitions, then adds support for the
Analog Devices ADG2404 multiplexer as the first user of this feature.

The enable GPIO allows the multiplexer to be disabled before changing
address lines and re-enabled after, preventing brief activation of
unintended channels during transitions. This is particularly important
for precision analog applications.

The ADG2404 is a 4:1 analog multiplexer with low 0.62Ω on-resistance
that requires this enable GPIO functionality for glitch-free operation.

Changes in v3:
 * Extend gpio-mux driver instead of creating standalone adg2404 driver
 * Make enable GPIO optional for backward compatibility
 * Add MUX_IDLE_DISCONNECT support via enable GPIO

You are developing on some old kernel. You got stale Cc list of at least
three people! How could you for example get "johan+linaro@kernel.org" -
from which maintainer entry - but that at least is not bouncing like two
others.

Probably from using get_maintainer.pl --git:

	$ scripts/get_maintainer.pl --git drivers/mux/gpio.c
	Peter Rosin [off-list ref] (maintainer:MULTIPLEXER
SUBSYSTEM)
	Srinivas Kandagatla [off-list ref]
(commit_signer:1/2=50%,authored:1/2=50%,added_lines:5/6=83%)
	Krzysztof Kozlowski [off-list ref] (commit_signer:1/2=50%)
	Bartosz Golaszewski [off-list ref] (commit_signer:1/2=50%)
	David Lechner [off-list ref]

A recent mailmap is indeed needed to remap Bartosz's old address,
though.

Yes, I've used "--to-cmd='./scripts/get_maintainer.pl --norolestats" when

sending the patches.

Then how did you get non-working Bartosz and Linus' emails?

I am on torvalds/linux latest master branch now. Here is the output of ./scripts/get_maintainer.pl --norolestats: 
Peter Rosin [off-list ref]
Rob Herring [off-list ref]
Krzysztof Kozlowski [off-list ref]
Conor Dooley [off-list ref]
Antoniu Miclaus [off-list ref]
Srinivas Kandagatla [off-list ref]
Bartosz Golaszewski [off-list ref]

Exactly. So why did you send it to:
Bartosz Golaszewski [off-list ref]
and
Linus Walleij [off-list ref]

I mean, this is the third time I am asking but you keep deflecting the
question with some sort of other data...
Best regards,
Krzysztof
