2016-02-25gpio: fix abi regression in sysfsBamvor Jian Zhang
We started to assign the gpio_device as parent for the sysfs but this changes the expected layout of sysfs. Restore the previous behaviour. Signed-off-by: Bamvor Jian Zhang <bamvor.zhangjian@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-25gpio: mb86s7x: Allow compile test buildAxel Lin
There is no build dependency for this driver, so enable COMPILE_TEST to get better build coverage. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-25gpio: pisosr: Use gpiod_set_value_cansleep in pisosr_gpio_refresh()Axel Lin
This driver has .can_sleep flag set. So the pisosr_gpio_get() can be called from contexts that can sleep. Thus use the cansleep() variant in pisosr_gpio_refresh(). Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

gpio->load_gpio is optional, so use devm_gpiod_get_optional instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2016-02-25gpio: rcar: Add Runtime PM handling for interruptsGeert Uytterhoeven
The R-Car GPIO driver handles Runtime PM for requested GPIOs only. When using a GPIO purely as an interrupt source, no Runtime PM handling is done, and the GPIO module's clock may not be enabled. To fix this: - Add .irq_request_resources() and .irq_release_resources() callbacks to handle Runtime PM when an interrupt is requested, - Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM when e.g. disabling/enabling an interrupt, or configuring the interrupt type. Fixes: d5c3d84657db57bd "net: phy: Avoid polling PHY with PHY_IGNORE_INTERRUPTS" Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-02-25gpio: Propagate all errors in devm_get_gpiod_from_child()Geert Uytterhoeven
devm_get_gpiod_from_child() tries several property suffixes to find a GPIO descriptor. If all suffixes fail and no probe deferral has been detected, it returns the error of the last try. However, if any but the last try fails with a real error (e.g. -EBUSY), this error is not propagated, and -ENOENT will be returned. This confuses drivers that e.g. want to detect if a GPIO is already in use. To fix this, change the loop logic to continue on -ENOENT, which indicates the property was not found and the next suffix should be tried, and propagate all other detected errors.
