powerpc/44x: Drop legacy-of-mm-gpiochip.h header

2025-09-06T10:37:11Z

Remove legacy-of-mm-gpiochip.h header file. The above mentioned file provides an OF API that's deprecated. There is no agnostic alternatives to it and we have to open code the logic which was hidden behind of_mm_gpiochip_add_data(). Note, most of the GPIO drivers are using their own labeling schemas and resource retrieval that only a few may gain of the code deduplication, so whenever alternative is appear we can move drivers again to use that one. As a side effect this change fixes a potential memory leak on an error path, if of_mm_gpiochip_add_data() fails.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06Z

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

powerpc: Switch to irq_find_mapping()

2025-05-16T19:06:12Z

irq_linear_revmap() is deprecated, so remove all its uses and supersede them by an identical call to irq_find_mapping().

powerpc: Switch to irq_domain_create_*()

2025-05-16T19:06:11Z

irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

Naming interrupt domains host is confusing at best and the irqdomain code uses both domain and host inconsistently. Therefore rename irq_set_default_host() to irq_set_default_domain().
