2013-04-26Merge branch 'samsung/exynos-multiplatform' into next/driversOlof Johansson1-1/+1
This merges in the revert of multiplatform support for exynos. Trivial conflicts on removed code. Also, needed to add "select COMMON_CLK" to the non-multiplatform EXYNOS config option. * samsung/exynos-multiplatform: Revert "ARM: exynos: enable multiplatform support" Signed-off-by: Olof Johansson <[email protected]>
2013-04-26Revert "ARM: exynos: enable multiplatform support"Olof Johansson1-1/+1
This reverts commit bd51de53e1be9896d815bbea30560262216d4616. Turns out that multiplatform breaks some uses cases, such as when you have an existing defconfig, since it adds the new EXYNOS_SINGLE config option as a dependecy. As a result, nearly all exynos config options will be disabled by default. Reverting instead of rebasing since this branch is pulled in as a dependency elsewhere.

2013-04-19ARM: exynos: enable multiplatform supportArnd Bergmann1-1/+1
This makes it possible to enable the exynos platform as part of a multiplatform kernel, in addition to keeping the single-platform exynos support. The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.

2013-04-12gpiolib-acpi: introduce acpi_get_gpio_by_index() helperMika Westerberg1-0/+77
Instead of open-coding ACPI GPIO resource lookup in each driver, we provide a helper function analogous to Device Tree version that allows drivers to specify which GPIO resource they are interested (using an index to the GPIO resources). The function then finds out the correct resource, translates the ACPI GPIO number to the corresponding Linux GPIO number and returns that.

We actually have to pass chip as the host_data parameter of irq_domain_add_simple() as later on, it is used to initialize chip_data in pca953x_gpio_irq_map().

2013-04-10gpio / ACPI: Handle ACPI events in accordance with the specRafael J. Wysocki1-20/+120
Commit 0d1c28a (gpiolib-acpi: Add ACPI5 event model support to gpio.) that added support for ACPI events signalled through GPIO interrupts covered only GPIO pins whose numbers are less than or equal to 255. However, there may be GPIO pins with numbers greater than 255 and the ACPI spec (ACPI 5.0, Section 5.6.5.1) requires the _EVT method to be used for handling events corresponding to those pins. Moreover, according to the spec, _EVT is the default mechanism for handling all ACPI events signalled through GPIO interrupts, so if the _Exx/_Lxx method is not present for the given pin, _EVT should be used instead. If present, though, _Exx/_Lxx take precedence over _EVT which shouldn't be executed in that case (ACPI 5.0, Section 5.6.5.3). Modify acpi_gpiochip_request_interrupts() to follow the spec as described above and add acpi_gpiochip_free_interrupts() needed to free interrupts associated with _EVT. Signed-off-by: Rafael J.

2013-04-10gpio/omap: force restore if context loss is not detectableJon Hunter1-8/+17
When booting with device-tree the function pointer for detecting context loss is not populated. Ideally, the pm_runtime framework should be enhanced to allow a means for reporting context/state loss and we could avoid populating such function pointers altogether. In the interim until a generic non-device specific solution is in place, force a restore of the gpio bank when enabling the gpio controller. Adds a new device-tree property for the OMAP GPIO controller to indicate if the GPIO controller is located in a power-domain that never loses power and hence will always maintain its logic state.

2013-04-10gpio/omap: optimise interrupt service routineJon Hunter1-7/+7
The OMAP GPIO interrupt service routine is checking each bit in the GPIO interrupt status register to see which bits are set. It is not efficient to check every bit especially if only a few bits are set. Therefore, instead of checking every bit use the __ffs() function, which returns the location of the first set bit, to find all the set bits. This optimisation was suggested-by and developed in collaboration with Felipe Balbi.

2013-04-03gpio: Renesas R-Car GPIO driver V3Magnus Damm3-0/+380
This patch is V3 of a GPIO driver for the R-Car series of SoCs from Renesas. This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on R-Car H1 (r8a7779). Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on a single I/O memory range and the 32 GPIOs are hooked up a single interrupt. In the case of R-Car H1 either external IRQ pins or GPIOs with interrupts can be used for on-board interupts. For external IRQs 4 pins are supported, and in the case of GPIO there are 202 GPIOS as 202 interrupts hooked up via 6 driver instances and to the GIC and the Cortex-A9 Quad. At this point this driver is interfacing as a regular platform device driver. In the future DT support will be submitted as an incremental feature patch.
