a5ec96ddfd gpio: it87: Add support for IT8613
This was tested on actual hardware and found to work fine, but currently
the official specifications of this chip could not be obtained to
confirm the numbers.

62885203f7 gpio: it87: add support for IT8718F Super I/O.
The DIO connector on the WAFER-945GSE is interfaced to GPIO ports
on the ITE IT8718F Super I/O chipset. From the datasheet of ITE IT8718F,
the GPIO interface is identical to IT8728, so just add it
to the same case as the other chip.

e35b5ab0a7 gpio: constify gpio_chip structures
These structures are only used to copy into other structures, so declare
them as const.

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.

0a38fd94c2 gpio: it87: use gpiochip data pointer
This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().
