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:

IRQ framework provides special type and getter to transform the Linux IRQ to the hardware pin. Use that type and getter function instead of direct access. While at it, amend an indentation in a couple of places. Signed-off-by:

The gpiod_find_by_fwnode() already checks for NULL and returns correct error code in case fwnode is invalid. Drop the respective check and assignment in the gpiod_find_and_request(). Signed-off-by:

It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool(). Signed-off-by:

The devprop prefix in the devprop_gpiochip_set_names() adds confusion. Get rid of it. Note we have more than one function in the same module that handles one or more device properties. This change will unify the naming schema for all of them. Signed-off-by:

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here). drivers/gpio/gpio-sama5d2-piobu.c:230:34: error: ‘sama5d2_piobu_ids’ defined but not used [-Werror=unused-const-variable=] 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:

The driver was implemented in a way that made the irqchip optional, if a irq was not present in the device tree. However, all of the device trees have always had an irq, so the optional-ness has never been used. Signed-off-by:
