One variant of the SX150X GPIO chip supports setting the pins in
open drain mode. This is currently available to set from platform
data, but completely unused in the kernel.
Activate the new .set_single_ended() callback so users can set
this up from e.g. device tree or board files using the new
GPIO descriptors.
As part of this, delete the platform data open drain setting
method.

The TPS65218 supports open drain mode on its three pins,
with one of them configurable also as push-pull. Use the
new .set_single_ended() callback to set this up properly
from the core, so the core actually see it can drive the
pin(s) as open drain, and does not attempt to emulate
open drain by switching the pin to an input.

If GPIO hog configuration failed while adding OF based
gpiochip() then return the error instead of ignoring it.
This helps of properly handling the gpio driver dependency.
When adding the gpio hog nodes for NVIDIA's Tegra210 platforms,
the gpio_hogd() fails with EPROBE_DEFER because pinctrl is not
ready at this time and gpio_request() for Tegra GPIO driver
returns error. The error was not causing the Tegra GPIO driver
to fail as the error was getting ignored.

Galileo Gen2 board uses the PCAL9535 as the GPIO expansion,
it is different from PCA9535 and includes interrupt mask/status registers,
The current driver does not support the interrupt registers configuration,
it causes some gpio pins cannot trigger interrupt events,

This makes use of the new .set_single_ended() callback to
set the GPIO line as open drain/open source using hardware.
The TC3589x can do this by either disabling the N-MOS
transistor (open drain) or the P-MOS transistor (open source)
of the output driver stage, in the first case making the signal
drive actively low and high impedance as "high" and in the second
case actively high and high impedance, which is as close to native
open drain support as we come.

Some GPIO controllers has a special hardware bit we can flip
to support open drain / source. This means that on these hardwares
we do not need to emulate OD/OS by setting the line to input
instead of actively driving it high/low. Add an optional vtable
callback to the driver set_single_ended() so that driver can
implement this in hardware if they have it.
We may need a pinctrl_gpio_set_config() call at some point to
propagate this down to a backing pin control device on systems
with split GPIO/pin control.

These chips seem to have a 9th GPIO block (thus supporting 72 GPIOs)
which is configured through SuperIO register 0xd2 (output enable) and
0xd3 (simple I/O). This is also the reason why io_size is larger than
on IT8728 / IT8732. Unfortunately I don't have hardware to test this 9th
GPIO block.
I am also not sure about not configuring the Simple I/O registers as the
hardware I have only uses GPIO block 8. Reading back the values of

The mcp23s18 is configurable on clearing the interrupt on either reading
INTCAP or GPIO. Since driver reads INTCAP in IRQ and not the GPIO reg need
to set control byte for this mode.

pca953x_gpio_set_multiple() divides by 4 to convert from longs to bytes,
which assumes a 32-bit platform, and is not correct on 64-bit platforms.
Use "sizeof(...)" instead to fix this.

The standby GPIO controller can be used as a interrupt controller.
Select GPIOLIB_IRQCHIP when compiling this driver. Otherwise we get
a compilation error:

Add support for the TPS65086 PMIC GPOs.
TPS65086 has four configurable GPOs that can be used for several
purposes. These are output only.
