gpio: Bulk conversion to generic_handle_domain_irq()

2021-08-12T10:39:38+00:00

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

gpio: gpio-altera: Add missing kerneldoc entry and demote comment

2020-07-08T07:24:07+00:00

'struct altera_gpio_chip's 'irq_chip' property is undocumented.  So
add property description to the struct's kerneldoc header.  Also
demote comment block which is clearly not in kerneldoc format.

Fixes the following W=1 warnings:

 drivers/gpio/gpio-altera.c:34: warning: Function parameter or member 'irq_chip' not described in 'altera_gpio_chip'
 drivers/gpio/gpio-altera.c:78: warning: Function parameter or member 'd' not described in 'altera_gpio_irq_set_type'
 drivers/gpio/gpio-altera.c:78: warning: Function parameter or member 'type' not described in 'altera_gpio_irq_set_type'

gpio: altera: change to platform_get_irq_optional to avoid false-positive error

2020-01-09T09:35:05+00:00

This patch switches to platform_get_irq_optional() from
platform_get_irq() as it causes a false-positive error such as 'IRQ
index 0 not found' when IRQ is not used. The IRQ usage is optional in
this gpio-altera driver, so the error log is undesirable.

gpio: altera: Pass irqchip when adding gpiochip

2019-07-03T08:24:12+00:00

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip.

For chained irqchips this is a pretty straight-forward
conversion.

gpio: altera: Allocate irq_chip dynamically

2019-06-10T14:24:22+00:00

Keeping the irq_chip definition static shares it with multiple instances
of the altera gpiochip in the system. This is bad and now we get this
warning from gpiolib core:

"detected irqchip that is shared with multiple gpiochips: please fix the
driver."

Hence, move the irq_chip definition from being driver static into the
struct altera_gpio_chips. So a unique irq_chip is used for each gpiochip
instance.

gpio: altera: Include GPIO driver header

This is a GPIO driver so it should definately include

gpio: Convert to using %pOF instead of full_name

2017-08-14T13:01:12+00:00

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.
