Some IOs can be needed during suspend_noirq/resume_noirq.
So move suspend/resume callbacks to noirq.

So have you checked that the pca953x_save_context() and restore works
this way? There's i2c traffic and regulators may sleep.. I wonder if
you instead just need to leave gpio-pca953x enabled in some cases
instead?

Yes I tested it, and it works (with my setup).
But this patch may have an impact for other people.
How could I leave it enabled in some cases ?

Regards,
