2018-07-10dt-bindings: gpio: pca953x: Document interrupts, update exampleGeert Uytterhoeven1-0/+3
The device can optionally supply an interrupt, hence document that. Add required GPIO properties to the example (extracted from a patch by Wolfram Sang). Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rob Herring <robh@kernel.org>
2018-05-16pca953x: add example how to use interrupt-controller and gpio-controllerH. Nikolaus Schaller1-0/+33
It is not completely obvious that these are required and how to use them. So we provide a tested example. Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2018-05-16DTS: Bindings: pca953x add an optional vcc-supply propertyH. Nikolaus Schaller1-0/+1
Hardware can have a switchable Vcc supply, so let's add it to the bindings (the current Linux driver code already supports it). Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2018-03-27gpio: pca953x: add compatibility for pcal6524 and pcal9555aH. Nikolaus Schaller1-0/+2
The Pyra-Handheld originally used the tca6424 but recently we have replaced it by the pin and package compatible pcal6524. So let's add this to the bindings and the driver. And while we are at it, the pcal9555a does not have a compatible entry either but is already supported by the device id table. Signed-off-by: H.

2017-12-03gpio: pca953x: fix vendor prefix for PCA9654Sergei Shtylyov1-1/+1
Despite commit 55020c8056a8 ("of: Add vendor prefix for ON Semiconductor Corp.") was made long ago, the latter commit 9f49f6dd0473 ("gpio: pca953x: add onsemi,pca9654 id") made use of another, undocumented vendor prefix. Since such prefix doesn't seem to be used in any device trees, I think we can just fix the "compatible" string in the driver and the bindings and be done with that...

2017-04-24gpio: DT bindings, move tca9554 from pcf857x to pca953xAnders Darander1-0/+1
The TCA9554 is similar to the PCA9554. Update the DT binding docs. Signed-off-by: Anders Darander <anders@chargestorm.se> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2017-01-11gpio: pca953x: Add optional reset gpio controlSteve Longerbeam1-0/+4
Add optional reset-gpios pin control. If present, de-assert the specified reset gpio pin to bring the chip out of reset. v2: - Specify that reset signal to PCA953x chip is active low, in binding doc. - reorder includes in gpio-pca953x.c. - remove dev_err() on devm_gpiod_get_optional() error return.
