* gpio: dwapb: remove dependenciesLinus Walleij2015-04-091-1/+0
| | | | | | | | | | | | | | | | | The Synopsys DesignWare DWAPB GPIO block is popular to synthesize amongst many architectures: X86, ARM, ARC. The driver was restricted to only these archs due to using [read|write]l_relaxed() accessors that were not universally available in the past, but as of commit 9439eb3ab9d1ece6e4ad7baaa4a7f534f9b9dab0 "asm-generic: io: implement relaxed accessor macros as conditional wrappers" these accessors are available on all archs so this should not be a problem any more. Enable the driver for all archs. Cc: Alexey Brodkin <Alexey.Brodkin@synopsys.com> Cc: Will Deacon <will.deacon@arm.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* gpio: dwapb: enable for ARCVineet Gupta2015-04-081-1/+1
| | | | | | | | | | | | | | | | Synopsys SDP platform uses DW GPIO controller in design with ARC cores. So adding ARC to architectures that may select this GPIO controller. Even though support for Synopsys SDP is yet to be submitted we'll need this tiny option enabled at least for properly working interrupts (DW GPIO controller is used as interrupt controller).

* gpio: removing kfree remove functionalityVarka Bhadram2015-04-082-2/+1
| | | | | | | | | | | | commit 3de07e5aaf290a0b58919 ("drivers: gpio: use devm_kzalloc") introduce devm_kzalloc() for allocating the memory. In this case kfree is not required to use. Above commit id introduced the bug that kfree is not removed from the remove function. This patch fix the above bug.

* gpio: mvebu: Fix mask/unmask managment per irq chip typeGregory CLEMENT2015-04-081-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Level IRQ handlers and edge IRQ handler are managed by tow different sets of registers. But currently the driver uses the same mask for the both registers. It lead to issues with the following scenario: First, an IRQ is requested on a GPIO to be triggered on front. After, this an other IRQ is requested for a GPIO of the same bank but triggered on level. Then the first one will be also setup to be triggered on level. It leads to an interrupt storm. The different kind of handler are already associated with two different irq chip type. With this patch the driver uses a private mask for each one which solves this issue. It has been tested on an Armada XP based board and on an Armada 375 board. For the both boards, with this patch is applied, there is no such interrupt storm when running the previous scenario. This bug was already fixed but in a different way in the legacy version of this driver by Evgeniy Dushistov: 9ece8839b1277fb9128ff6833411614ab6c88d68 "ARM: orion: Fix for certain sequence of request_irq can cause irq storm". The fact the new version of the gpio drive could be affected had been discussed there: http://thread.gmane.org/gmane.linux.ports.arm.kernel/344670/focus=364012 Reported-by: Evgeniy A.

| | | | | | | | | | | | | When the GPIO module is needed for wake-up, it's module clock must not be disabled. Hence implement irq_chip.irq_set_wake(), which increments/decrements the clock's enable_count when needed, and forwards the wake-up state to the upstream interrupt controller. This fixes wake-up from s2ram using gpio-keys when using a PM Domain to manage the module clock.
