Linus Torvalds c0f234ff90 gpio: updates for v6.2
GPIO core:
 - teach gpiolib to work with software nodes for HW description
 - remove ARCH_NR_GPIOS treewide as we no longer impose any limit on the number
   of GPIOS since the allocation became entirely dynamic
 - add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC controller,
   Freescale PCIe and Ethernet controller, Himax LCDs and Mediatek mt2701
 - refactor OF quirk code
 - some general refactoring of the OF and ACPI code, adding new helpers, minor
   tweaks and fixes, making fwnode usage consistent etc.
 
 GPIO uAPI:
 - fix an issue where the user-space can trigger a NULL-pointer dereference in
   the kernel by opening a device file, forcing a driver unbind and then calling
   one of the syscalls on the associated file descriptor
 
 New drivers:
 - add gpio-latch: a new GPIO multiplexer based on latches connected to other
   GPIOs
 
 Driver updates:
 - convert i2c GPIO expanders to using .probe_new()
 - drop the gpio-sta2x11 driver
 - factor out common code for the ACCES IDIO-16 family of controllers and use
   this new library wherever applicable in drivers
 - add DT support to gpio-hisi
 - allow building gpio-davinci as a module and increase its maxItems property
 - add support for a new model to gpio-pca9570
 - other minor changes to various drivers
