44896beae6 gpio: pca953x: add PCAL9535 interrupt support for Galileo Gen2
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 patch fix this issue.

8b866b0682 gpio: tc3589x: implement open drain/source callback
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.

c663e5f567 gpio: support native single-ended hardware drivers
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.

8fccdb580e gpio: gpio-it87: Add support for IT8620 and IT8628
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
0xc0-0xc7 (as configured by the BIOS/EFI on my board) shows that all
have 0xff set.

ab503238ff powerpc: ppc4xx: drop unused variable
commit 0d36fe65f5
"powerpc: ppc4xx: use gpiochip data pointer"
made the mm_gc local variable in ppc4xx_gpio_set()
redundant, and when GCC treats warnings as errors this
happens:

arch/powerpc/sysdev/ppc4xx_gpio.c: In function 'ppc4xx_gpio_set':
arch/powerpc/sysdev/ppc4xx_gpio.c:93:26: error:
  unused variable 'mm_gc' [-Werror=unused-variable]
     struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc);
                             ^
   cc1: all warnings being treated as errors
