gpio: add gpiod_toggle_active_low()

2020-02-19T18:53:09Z

[ 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: 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.

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

gpio: updates for v5.4 - use a helper variable for &pdev->dev in gpio-em - tweak the ifdefs in GPIO headers - fix function links in HTML docs - remove an unneeded error message from ixp4xx - use the optional clk_get in gpio-mxc instead of checking the return value - a couple improvements in pca953x - allow to build gpio-lpc32xx on non-lpc32xx targets

gpio: Use callback presence to determine need of valid_mask

2019-08-20T08:42:07Z

After we switched the two drivers that have .need_valid_mask set to use the callback for setting up the .valid_mask, we can just use the presence of the .init_valid_mask() callback (or the OF reserved ranges, nota bene) to determine whether to allocate the mask or not and we can drop the .need_valid_mask field altogether.

gpio: Pass mask and size with the init_valid_mask()

2019-08-20T08:42:07Z

It is more helpful for drivers to have the affected fields directly available when we use the callback to set up the valid mask. Change this and switch over the only user (MSM) to use the passed parameters. If we do this we can also move the mask out of publicly visible struct fields.
