* gpio: sx150x: fixup OF supportLinus Walleij2015-01-22
| | | | | | | | | Make OF conditional on CONFIG_OF_GPIO, rename and register the match table. Reported-by: Mike Krinkin <krinkin.m.u@gmail.com> Cc: Wei Chen <Wei.Chen@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: sx150x: add dts support for sx150x driverWei Chen2015-01-19
| | | | | | | | | Current sx150x gpio expander driver doesn't support DTS. Now we added dts support for this driver. Signed-off-by: Wei Chen <Wei.Chen@csr.com> Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* gpio: sx150x: add support for sx1506 gpio expander deviceWei Chen2015-01-15
| | | | | | | | | | | | | | semtech has two series of sx150x gpio expanders: sx150x-456 and sx150x-789. The current gpio-150x driver in linux only support sx1508 and sx1509. We added sx1506 support code into this driver. Signed-off-by: Wei Chen <Wei.Chen@csr.com> Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: sx150x: move to irqdomain framework for sx150x driverWei Chen2015-01-15
| | | | | | | | | | | | | The sx150x gpio driver used a loop to set liner irq map for gpio pins. Now we use the irq domain to rebuild this irq mappig and make sure the codes are still compatible to old users. this patch also adds IRQF_ONESHOT flag to fix the IRQ flooding issues.

* gpio/pinctrl: make gpio_chip members typed booleanLinus Walleij2013-12-04
| | | | | | | | | | | This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
