gpio: mvebu: Slightly optimize mvebu_gpio_irq_handler()

2025-10-20T08:24:03+00:00

In the main loop of mvebu_gpio_irq_handler() some calls to
irq_find_mapping() can be saved.

There is no point to find an irq number before checking if this something
has to be done.
By testing first, some calls can be saved.

gpio: mvebu: don't print out global GPIO numbers in debugfs callbacks

2025-09-03T07:38:13+00:00

In order to further limit the number of references to the GPIO base
number stored in struct gpio_chip, replace the global GPIO numbers in
the output of debugfs callbacks by hardware offsets.

gpio: remove unneeded 'fast_io' parameter in regmap_config

2025-08-14T07:08:33+00:00

When using MMIO with regmap, fast_io is implied. No need to set it
again.

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.

gpio: Use dev_fwnode() where applicable across drivers

2025-06-16T07:42:24+00:00

irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().

So use the dev_fwnode() helper where applicable.

Pull irq cleanups from Thomas Gleixner:
 "A set of cleanups for the generic interrupt subsystem:

   - Consolidate on one set of functions for the interrupt domain code
     to get rid of pointlessly duplicated code with only marginal
     different semantics.

   - Update the documentation accordingly and consolidate the coding
     style of the irqdomain header"

gpio: Switch to irq_domain_create_*()

2025-05-16T19:06:09+00:00

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).

gpio: mvebu: use value returning setters

2025-02-26T10:17:40+00:00

struct gpio_chip now has additional variants of the set(_multiple)
driver callbacks that return an integer to indicate success or failure.
Convert the driver to using them.

gpio: Use str_enable_disable-like helpers

2025-02-03T08:12:44+00:00

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read.  Ternary
   operator has three arguments and with wrapping might lead to quite
   long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
   file.
