gpio: fix gpio-adp5588 build errors

2019-10-05T15:19:46+00:00

commit e9646f0f5bb62b7d43f0968f39d536cfe7123b53 upstream. The gpio-adp5588 driver uses interfaces that are provided by GPIOLIB_IRQCHIP, so select that symbol in its Kconfig entry. Fixes these build errors: ../drivers/gpio/gpio-adp5588.c: In function ‘adp5588_irq_handler’: ../drivers/gpio/gpio-adp5588.c:266:26: error: ‘struct gpio_chip’ has no member named ‘irq’ dev->gpio_chip.irq.domain, gpio)); ^ ../drivers/gpio/gpio-adp5588.c: In function ‘adp5588_irq_setup’: ../drivers/gpio/gpio-adp5588.c:298:2: error: implicit declaration of function ‘gpiochip_irqchip_add_nested’ [-Werror=implicit-function-declaration] ret = gpiochip_irqchip_add_nested(&dev->gpio_chip, ^ ../drivers/gpio/gpio-adp5588.c:307:2: error: implicit declaration of function ‘gpiochip_set_nested_irqchip’ [-Werror=implicit-function-declaration] gpiochip_set_nested_irqchip(&dev->gpio_chip, ^ Fixes: 459773ae8dbb ("gpio: adp5588-gpio: support interrupt controller") Reported-by: kbuild test robot Signed-off-by: Randy Dunlap Cc: linux-gpio@vger.kernel.org Reviewed-by: Bartosz Golaszewski Acked-by: Michael Hennerich Signed-off-by: Linus Walleij Signed-off-by: Ben Hutchings

gpio: Fix OF build problem on UM

2016-11-20T01:17:13+00:00

commit 2527ecc9195e9c66252af24c4689e8a67cd4ccb9 upstream. The UserMode (UM) Linux build was failing in gpiolib-of as it requires ioremap()/iounmap() to exist, which is absent from UM. The non-existence of IO memory is negatively defined as CONFIG_NO_IOMEM which means we need to depend on HAS_IOMEM.

gpio: select IRQ_DOMAIN for gpiolib irqchip helpers

2014-05-29T14:52:46+00:00

These helpers depend on the IRQ_DOMAIN so select it explicitly, as it will not be present on all platforms such as Intel desktops and laptops using Intel-MID. Signed-off-by: Linus Walleij

gpio: pca953x: use gpiolib irqchip helpers

2014-05-28T13:29:23+00:00

This switches the PCA953x driver over to using the gpiolib irqchip helpers to handle the threaded interrups cascaded off this GPIO chip. Signed-off-by: Linus Walleij

gpio: Add run-time dependencies to R-Car driver

2014-05-27T13:44:10+00:00

The Renesas R-Car GPIO driver is only useful on shmobile unless build testing. Signed-off-by: Jean Delvare Cc: Magnus Damm Cc: Alexandre Courbot Acked-by: Simon Horman Signed-off-by: Linus Walleij

gpio-pch: Fix Kconfig dependencies

2014-05-23T11:24:42+00:00

The gpio-pch driver is for a companion chip to the Intel Atom E600 series processors. These are 32-bit x86 processors so the driver is only needed on X86_32. Add COMPILE_TEST as an alternative, so that the driver can still be build-tested elsewhere. Signed-off-by: Jean Delvare Cc: Linus Walleij Cc: Alexandre Courbot Signed-off-by: Linus Walleij

gpio: always enable GPIO_OMAP on ARCH_OMAP

2014-05-09T07:46:32+00:00

Commit 4df42de9d3e "gpio: omap: add a GPIO_OMAP option instead of using ARCH_OMAP" made it possible to build OMAP kernels without the GPIO driver, which at least on OMAP2 and OMAP3 causes build errors because of functions used by the platform power management code: arch/arm/mach-omap2/built-in.o: In function `omap_sram_idle': arch/arm/mach-omap2/pm24xx.c:129: undefined reference to `omap2_gpio_prepare_for_idle' arch/arm/mach-omap2/pm24xx.c:129: undefined reference to `omap2_gpio_resume_after_idle' We presumably always want the GPIO driver on OMAP, so this adds a slightly broader dependency and only allows disabling the driver only when no OMAP2PLUS platform is selected. However, it seems entirely reasonable to include the driver in build tests on other platforms, so we should also allow building it for COMPILE_TEST builds and select the required GENERIC_IRQ_CHIP that may not already be enabled on other platforms.

gpio: omap: convert driver to use gpiolib irqchip

Converts the GPIO OMAP driver to register its chained irq handler and irqchip using the helpers in the gpiolib core. Signed-off-by: Javier Martinez Canillas Tested-by: Tony Lindgren Signed-off-by: Linus Walleij

gpio: omap: add a GPIO_OMAP option instead of using ARCH_OMAP

2014-04-28T19:35:08+00:00

The ARCH_OMAP config option was used to built the GPIO OMAP driver but this is not consistent with the rest of the GPIO drivers that have their own Kconfig option. Also, this make it harder to add dependencies or reverse dependencies (i.e: select) since that would mean touching the sub-arch config option. So is better to add a boolean Kconfig option for this driver that defaults to true if ARCH_OMAP is enabled.

gpio: timberdale: simplify dependencies

2014-04-28T19:35:07+00:00

GPIO_TIMBERDALE doesn't need an explicit dependency on HAS_IOMEM, because it depends on MFD_TIMBERDALE which itself depends on HAS_IOMEM already. Signed-off-by: Jean Delvare Cc: Linus Walleij Cc: Alexandre Courbot Signed-off-by: Linus Walleij
