gpio: add gpiod_toggle_active_low()

2020-02-19T18:54:13Z

[ Upstream commit d3a5bcb4a17f1ad072484bb92c42519ff3aba6e1 ] Add possibility to toggle active-low flag of a gpio descriptor. This is useful for compatibility code, where defaults are inverted vs DT gpio flags or the active-low flag is taken from elsewhere.

gpiolib: Introduce ->add_pin_ranges() callback

2019-11-13T13:30:30Z

When IRQ chip is being added by GPIO library, the ACPI based platform expects GPIO <-> pin mapping ranges to be initialized in order to correctly initialize ACPI event mechanism on affected platforms. Unfortunately this step is missed. Introduce ->add_pin_ranges() callback to fill the above mentioned gap.

gpio: Add definition for GPIO direction

2019-11-07T08:19:39Z

At least for me it is difficult to remember the meaning of GPIO direction values. Define GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT so that occasional GPIO contributors would not need to always check the meaning of hard coded values 1 and 0.

gpiolib: Initialize the hardware with a callback

2019-10-14T23:18:46Z

After changing the drivers to use GPIO core to add an IRQ chip it appears that some of them requires a hardware initialization before adding the IRQ chip. Add an optional callback ->init_hw() to allow that drivers to initialize hardware if needed. This change is a part of the fix NULL pointer dereference brought to the several drivers recently.

gpiolib: introduce fwnode_gpiod_get_index()

2019-10-03T10:04:28Z

This introduces fwnode_gpiod_get_index() that iterates through common gpio suffixes when trying to locate a GPIO within a given firmware node. We also switch devm_fwnode_gpiod_get_index() to call fwnode_gpiod_get_index() instead of iterating through GPIO suffixes on its own.

gpiolib: introduce devm_fwnode_gpiod_get_index()

2019-10-03T10:03:58Z

devm_fwnode_get_index_gpiod_from_child() is too long, besides the fwnode in question does not have to be a child of device node. Let's rename it to devm_fwnode_gpiod_get_index() and keep the old name for compatibility for now. Also let's add a devm_fwnode_gpiod_get() wrapper as majority of the callers need a single GPIO.

gpio: Initialize the irqchip valid_mask with a callback

2019-09-11T00:09:37Z

After changing the valid_mask for the struct gpio_chip to detect the need and presence of a valid mask with the presence of a .init_valid_mask() callback to fill it in, we augment the gpio_irq_chip to use the same logic. Switch all driver using the gpio_irq_chio valid_mask over to this new method. This makes sure the valid_mask for the gpio_irq_chip gets filled in when we add the gpio_chip, which makes it a little easier to switch over drivers using the old way of setting up gpio_irq_chip over to the new method of passing the gpio_irq_chip along with the gpio_chip. (See drivers/gpio/TODO for details.)

gpio: Fix up merge collision in include file

2019-09-05T09:20:25Z

The merge of two different patch sets cleaning around in the main driver include file collided making the function declarations for gpiochip_[un]lock_as_irq() be defined twice when gpiolib was unselected. Fix it up. Cc: YueHaibing Cc: Masahiro Yamada Reported-by: kbuild test robot Signed-off-by: Linus Walleij
