MIPS: Alchemy: Remove bogus static/inline specifiers

2025-12-15T15:09:46+00:00

The recent io_remap_pfn_range() rework applied the static and inline specifiers to the implementation of io_remap_pfn_range_pfn() on MIPS Alchemy, mirroring the same change on other platforms. However, this function is defined in a source file and that definition causes a conflict with its declaration. Fix this by dropping the specifiers.

mm: abstract io_remap_pfn_range() based on PFN

2025-11-17T01:28:12+00:00

The only instances in which we customise this function are ones in which we customise the PFN used. Instances where architectures were not passing the pgprot value through pgprot_decrypted() are ones where pgprot_decrypted() was a no-op anyway, so we can simply always pass pgprot through this function. Use this fact to simplify the use of io_remap_pfn_range(), by abstracting the PFN via io_remap_pfn_range_pfn() and using this instead of providing a general io_remap_pfn_range() function per-architecture.

syscore: Pass context data to callbacks

2025-11-14T09:01:52+00:00

Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework. Add a void * driver data field for drivers to store contextual data that will be passed to the syscore ops. Acked-by: Rafael J. Wysocki (Intel) Signed-off-by: Thierry Reding

MIPS: Alchemy: convert from round_rate() to determine_rate()

2025-08-29T20:34:29+00:00

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch appended to the "under-the-cut" portion of the patch. Note that prior to running Coccinelle, alchemy_clk_aux_roundr() was renamed to alchemy_clk_aux_round_rate(). A few minor style cleanups were also done by hand.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

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
