2018-08-10gpio: it87: Add support for IT8613Leonid Bloch
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. Signed-off-by: Leonid Bloch <lbloch@janustech.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2018-08-10gpio: it87: add support for IT8718F Super I/O.Ivan Podovalov
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.

2016-09-13gpio: constify gpio_chip structuresJulia Lawall
These structures are only used to copy into other structures, so declare them as const. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct gpio_chip i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct gpio_chip e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct gpio_chip i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-03-31gpio: gpio-it87: Add support for IT8620 and IT8628Martin Blumenstingl
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.

2016-01-05gpio: it87: use gpiochip data pointerLinus Walleij
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(). Cc: Diego Elio Pettenò <flameeyes@flameeyes.eu> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-10-02gpio: add GPIO support for IT87xx, replacing gpio-it8761eDiego Elio Pettenò
