0b32928528 pinctrl: at91: Enable slewrate by default on SAM9X60
On SAM9X60, slewrate should be enabled on pins with a switching frequency
below 50Mhz. Since most of our pins do not exceed this value, we enable
slewrate by default. Pins with a switching value that exceeds 50Mhz will
have to explicitly disable slewrate.

This patch changes the ABI. However, the slewrate macros are only used
by SAM9X60 and, at this moment, there are no device-tree files available
for this platform.

884caadad1 pinctrl: sh-pfc: sh7734: Fix duplicate TCLK1_B
The definitions for bit field [19:18] of the Peripheral Function Select
Register 3 were accidentally copied from bit field [20], leading to
duplicates for the TCLK1_B function, and missing TCLK0, CAN_CLK_B, and
ET0_ETXD4 functions.

Fix this by adding the missing GPIO_FN_CAN_CLK_B and GPIO_FN_ET0_ETXD4
enum values, and correcting the functions.

As platform_get_irq() now prints an error when the interrupt does not

3739898576 pinctrl: cherryview: Fix irq_valid_mask calculation
Commit 03c4749dd6c7 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux
GPIO translation") has made the cherryview gpio numbers sparse, to get
a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux.

This has greatly simplified things, but the code setting the
irq_valid_mask was not updated for this, so the valid mask is still in
the old "compressed" numbering with the gaps in the pin numbers skipped,
which is wrong as irq_valid_mask needs to be expressed in gpio numbers.

This results in the following error on devices using pin 24 (0x0018) on
the north GPIO controller as an ACPI event source:

[    0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ

This has been reported (by email) to be happening on a Caterpillar CAT T20
tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1.

This commit uses the pin number instead of the compressed index into
community->pins to clear the correct bits in irq_valid_mask for GPIOs
using GPEs for interrupts, fixing these errors and in case of the
Medion Akoya e2215t also fixing the LID switch not working.

4973ddc842 pinctrl: intel: Avoid potential glitches if pin is in GPIO mode
When consumer requests a pin, in order to be on the safest side,
we switch it first to GPIO mode followed by immediate transition
to the input state. Due to posted writes it's luckily to be a single
I/O transaction.

However, if firmware or boot loader already configures the pin
to the GPIO mode, user expects no glitches for the requested pin.
We may check if the pin is pre-configured and leave it as is
till the actual consumer toggles its state to avoid glitches.

c136d4c71f pinctrl: aspeed-g6: Make SIG_DESC_CLEAR() behave intuitively
Signal descriptors can represent multi-bit bitfields and so have
explicit "enable" and "disable" states. However many descriptor
instances only describe a single bit, and so the SIG_DESC_SET() macro is
provides an abstraction for the single-bit cases: Its expansion
configures the "enable" state to set the bit and "disable" to clear.

SIG_DESC_CLEAR() was introduced to provide a similar single-bit
abstraction for for descriptors to clear the bit of interest. However
its behaviour was defined as the literal inverse of SIG_DESC_SET() - the
impact is the bit of interest is set in the disable path. This behaviour
isn't intuitive and doesn't align with how we want to use the macro in
practice, so make it clear the bit for both the enable and disable
paths.

b95e0bd23e pinctrl: nomadik: Drop support for latent IRQ
The latent IRQs are IRQs that have occurred when the system
was down in deep sleep and the GPIO block was powered off.
The PRCMU (power reset and control unit) knows which GPIO
line offset fired an IRQ to wake the system up (if so
desired) and this second IRQ was used to replay the action
when the system came back online after suspend().

This is now known to be the wrong approach to solve this
problem: in a patch series Lina Iyer has suggested to
instead make it possible to model the IRQs as hierarchical
with double parents.

Also the current device trees do not contain the right
information to make this code work, the latent IRQ is not
specified nowadays giving noise like this in the console:

[    0.612168] gpio 8012e000.gpio: IRQ index 1 not found
[    0.622523] gpio 8012e080.gpio: IRQ index 1 not found

Let's delete the latent IRQ code and reimplement it properly
when we need it.

When an STMFX IO is used as interrupt through the interrupt-controller
binding, the STMFX driver should configure this IO as input. Default
value of STMFX IO direction is input, but if the IO is used as output
before the interrupt use, it will not work without these callbacks.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion: the ST pin controller errors out of adding a
irqchip if the interrupt is invalid or missing or if the
irqmux is not present: the irqchip should not be added
if either of these errors happen, so rewrite the code to
deal with that. Keep the exit path where the gpio_chip
is added no matter what the status of the irq is.

For chained irqchips this is a pretty straight-forward

up to 3 gpio_chips with the same parent handler, but just
passing girq->parent_handler and the parent on the first
of them should cut it.
