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.

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.

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.

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.

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

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

Converts the GPIO OMAP driver to register its chained irq
handler and irqchip using the helpers in the gpiolib core.

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.

gpio: tc3589x: use gpiolib irqchip helpers

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

Now that the gpiolib irqchip helpers can support nested, threaded
IRQ handlers, switch the TC3589x driver over to using this new
infrastructure. Tested on the Ux500.

Merge tag 'drivers-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2014-04-05T22:37:40+00:00

Pull ARM SoC driver changes from Arnd Bergmann:
 "These changes are mostly for ARM specific device drivers that either
  don't have an upstream maintainer, or that had the maintainer ask us
  to pick up the changes to avoid conflicts.

  A large chunk of this are clock drivers (bcm281xx, exynos, versatile,
  shmobile), aside from that, reset controllers for STi as well as a
  large rework of the Marvell Orion/EBU watchdog driver are notable"
