Merge tag 'intel-gpio-v5.18-1' of gitolite.kernel.org:pub/scm/linux/kernel/git/andy/linux-gpio-intel into gpio/for-next

intel-gpio for v5.18-1

* Set IRQ bus token in gpio-crystalcove to avoid debugfs error
* Check return value of kstrdup() in gpio-merrifield to error out earlier
* Clean up couple of drivers from unneeded of_node usage
* Allow gpio-tps68470 to be built as module to reduce memory foot print

 	  Select this option to enable GPIO driver for the TPS68470
···
 	  by the TPS68470. While the 7 GPIOs can be configured as
 	  input or output as appropriate, the sensor related GPIOs
 	  are "output only" GPIOs.
-
-	  This driver config is bool, as the GPIO functionality
-	  of the TPS68470 must be available before dependent
-	  drivers are loaded.
