Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.6 kernel cycle. This is a pretty calm cycle so far, nothing special going on really. Some more changes will come in from the irqchip and pin control trees. I also deleted an orphan include file for FMC that was dangling since subsystem was removed. Core changes: - Document the usecases for the kernelspace vs userspace handling of GPIOs. - Handle MSI (message signalled interrupts) properly in the core hierarchical irqdomain code. - Fix a rare race condition while initializing the descriptor array. New drivers: - Xylon LogiCVC GPIO driver. - WDC934x GPIO controller driver. Driver improvements: - Implemented suspend/resume in the Tegra driver. - MPC8xx edge detection fixup. - Properly convert ThunderX to use hierarchical irqdomain with GPIOLIB_IRQCHIP on top of the revert of the previous buggy switchover. This time it works (hopefully).

gpio: Drop the chained IRQ handler assign function

2020-01-23T14:54:32Z

gpiochip_set_chained_irqchip() would assign a chained handler to a GPIO chip. We now populate struct gpio_irq_chip for all chained GPIO irqchips so drop this function.

gpio: Fix the no return statement warning

2020-01-16T10:27:12Z

In commit 242587616710 ("gpiolib: Add support for the irqdomain which doesn't use irq_fwspec as arg") we have changed the return type of gpiochip_populate_parent_fwspec_twocell/fourcell() from void to void *, but forgot to add a return statement for these two dummy functions. Add "return NULL" to fix the build warnings.

gpiolib: Add support for the irqdomain which doesn't use irq_fwspec as arg

2020-01-15T10:17:44Z

Some gpio's parent irqdomain may not use the struct irq_fwspec as argument, such as msi irqdomain. So rename the callback populate_parent_fwspec() to populate_parent_alloc_arg() and make it allocate and populate the specific struct which is needed by the parent irqdomain.

gpiolib: convert the type of hwnum to unsigned int in gpiochip_get_desc()

2020-01-07T11:03:28Z

gpiochip_get_desc() takes a u16 hwnum, but it turns out most users don't respect that and usually pass an unsigned int. Since implicit casting to a smaller type is dangerous - let's change the type of hwnum to unsigned int in gpiochip_get_desc() and in gpiochip_request_own_desc() where the size of hwnum is not respected either and who's a user of the former. This is safe as we then check the hwnum against the number of lines before proceeding in gpiochip_get_desc().

gpio: add gpiod_toggle_active_low()

2019-12-18T12:36:02Z

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.
