Merge tag 'pinctrl-v6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control fixes from Linus Walleij:

 - Mark som pins as invalid for IRQ use in the Qualcomm driver

 - Fix up the use of device properties on the MA35DX Nuvoton, apparently
   something went sidewise

 - Clear the GPIO debounce settings when going down for suspend in the
   AMD driver. Very good for some AMD laptops that now wake up from
   suspend again!

 - Add the compulsory .can_sleep bool flag in the AW9523 driver, should
   have been there from the beginning, now there are users finding the
   bug

 - Drop some bouncing email address from MAINTAINERS
