At Huawei Matebook D15 two different GPIOs are used to control the output:
	- gpio0 controls the speaker output;
	- gpio1 controls the headphone output.

Changing both at the same time cause spurious events that are mis-interpreted
as input events, causing troubles on apps. So, a delay is needed before turning
on such gpios.

With this patch, plugging a headphone causes a jack event to trigger the speaker
supply, powering down the speaker and powering up the headphone output.
Removing the headphone also triggers the power supply, powering up the speaker
and powering down the headphone.

There is something weird with the patches here, at least for me in Thunderbird
both patches show up as nameless attachments to emails with empty bodies.

After saving the attachments the patches look good to me, so:

Acked-by: Hans de Goede <hdegoede@redhat.com>

for the series.

Weird... I tested here on Thunderbird (Fedora 35), reading it from the ML
and they opened ok here.

There *is* an issue on such patches though: they ended using my past
e-mail :-) 

I'll re-send those with your ack using the right SoB/From
mchehab@kernel.org.

Yes I checked lore.kernel.org and they look fine there, so as you
said: weird.

And in the resend they look fine in my Thunderbird too.
