According to the reference manual level interrupts can't be acked
using the IRQSTAT registers. The effect is that when a level interrupt
triggers the following ack is a no-op and the same interrupt triggers
again right after it has been unmasked after running the interrupt
handler.
The reference manual says:
Status bits for pins configured as level sensitive interrupts cannot be
cleared unless either the actual pin is in the non-interrupting state, or
the pin has been disabled as an interrupt source by clearing its bit in
HW_PINCTRL_PIN2IRQ.
To work around the duplicated interrupts we can use the PIN2IRQ
rather than the IRQEN registers to mask the interrupts. This
probably does not work for the edge interrupts, so we have to split up
the irq chip into two chip types, one for the level interrupts and
one for the edge interrupts. We now make use of two different enable
registers, so we have to take care to always enable the right one,
especially during switching of the interrupt type. An easy way
to accomplish this is to use the IRQCHIP_SET_TYPE_MASKED which
makes sure that set_irq_type is called with masked interrupts. With this
the flow to change the irq type is like:
- core masks interrupt (using the current chip type)
- mxs_gpio_set_irq_type() changes chip type if necessary
- mxs_gpio_set_irq_type() unconditionally sets the enable bit in the
now unused enable register
- core eventually unmasks the interrupt (using the new chip type)

This makes it mandatory to have exactly 3 arguments for GPIOs and then
converts gpiolib to use of __acpi_node_get_property_reference() instead. In

Since the I2C sx150x GPIO expander driver uses platform_data to manage
the pins configurations, rewrite the driver as a pinctrl driver using
pinconf to get/set pin configurations from DT or debugfs.
The pinctrl driver is functionnally equivalent as the gpio-only driver
and can use DT for pinconf. The platform_data confirmation is dropped.
This patchset removed the gpio-only driver and selects the Pinctrl driver
config instead. This patchset also migrates the gpio dt-bindings to pinctrl
and add the pinctrl optional properties.
The driver was tested with a SX1509 device on a BeagleBone black with
interrupt support and on an X86_64 machine over an I2C to USB converter.
This is a fixed version that builds and runs on non-OF platforms and on
arm based OF. The GPIO version is removed and the bindings are also moved
to the pinctrl bindings.
Changes since v2
- rebased on v4.9-rc1
- removed MODULE_DEVICE_TABLE as in upstream bb411e771b
("gpio: sx150x: fix implicit assumption module.h is present")
Changes since v1
- Fix Kconfig descriptions on pinctrl and gpio
- Fix Kconfig dependency
- Remove oscio support for non-789 devices
- correct typo in dt bindings
- remove probe reset for non-789 devices
Changes since RFC
- Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms
- No more rely on OF_GPIO config
- Moved and enhanced bindings to pinctrl bindings
- Removed gpio-sx150x.c
- Temporary select PINCTRL_SX150X when GPIO_SX150X
- Temporary mark GPIO_SX150X as deprecated
