Convert the driver to immutable irq-chip with a bit of intuition. In this case I had to figure out a way to get to the struct gpio_chip that would work even when the irq_chip is not part of the driver state container. I did this by just doing what most other GPIO drivers do and pass the state struct as data to devm_gpiochip_add_data() and rewrite accordingly. Cc: Marc Zyngier <maz@kernel.org> Signed-off-by:

The 104-DIO-48E lacks an IRQ status register. Rather than use the Clear Interrupt register as the status register, set the no_status flag to true and thus avoid such a hack. Reviewed-by:

Merge tag 'regmap-no-status' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap into gpio/for-next regmap: Add no_status support This patch adds support for devices which don't support readback of individual interrupt statuses, we report all interrupts as firing and hope the consumers do the right thing.

Add minimal driver for Fairchild FXL6408 8-bit I2C-controlled GPIO expander using the generic regmap based GPIO driver (GPIO_REGMAP). The driver implements setting the GPIO direction, reading inputs and writing outputs. In addition to that the FXL6408 has the following functionalities: - allows to monitor input ports for data transitions with an interrupt pin - all inputs can be configured with pull-up or pull-down resistors Datasheet: https://www.onsemi.com/download/data-sheet/pdf/fxl6408-d.pdfSigned-off-by:

The true Hi-Z (a.k.a. high impedance) mode is when pin is completely disconnected from the chip. This includes input buffer as well. Nevertheless, some hardware may not support that mode and they are considering input only as Hi-Z, but more precisely it is an equivalent to that, in electronics it's basically "an antenna mode". Sligthly correct documentation to take the above into consideration. Signed-off-by:

Convert the driver to immutable irq-chip with a bit of intuition. This driver require some special care: .irq_ack() was copied from dummy_irq_chip where it was defined as noop. This only makes sense if using handle_edge_irq() that will unconditionally call .irq_ack() to avoid a crash, but this driver is not ever using handle_edge_irq() so just avoid assigning .irq_ack(). A separate chip had to be created for the non-wakeup instance. Cc: Marc Zyngier <maz@kernel.org> Reviewed-by:
