The alive pin controller on exynos7 does not support external gpio interrupts. Hence, remove the eint_gpio_init call-back for it. This fixes the following error message seen during exynos7 boot-up: "samsung-pinctrl 10580000.pinctrl: irq number not available" Signed-off-by: Abhilash Kesavan <a.kesavan@samsung.com> Acked-by: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
This patch adds driver data for Exynos5433 SoC. Exynos5433 includes 228 multi- functional input/output port pins and 135 memory port pins. There are 41 general port groups and 2 memory port groups.

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

Pull take two of the GPIO updates:
"Same stuff as last time, now with a fixup patch for the previous
compile error plus I ran a few extra rounds of compile-testing.
This is the bulk of GPIO changes for the v3.19 series:
- A new API that allows setting more than one GPIO at the time. This
is implemented for the new descriptor-based API only and makes it
possible to e.g. toggle a clock and data line at the same time, if
the hardware can do this with a single register write. Both
consumers and drivers need new calls, and the core will fall back
to driving individual lines where needed. Implemented for the
MPC8xxx driver initially
- Patched the mdio-mux-gpio and the serial mctrl driver that drives
modems to use the new multiple-setting API to set several signals
simultaneously
- Get rid of the global GPIO descriptor array, and instead allocate
descriptors dynamically for each GPIO on a certain GPIO chip. This
moves us closer to getting rid of the limitation of using the
global, static GPIO numberspace
- New driver and device tree bindings for 74xx ICs
- New driver and device tree bindings for the VF610 Vybrid
- Support the RCAR r8a7793 and r8a7794
- Guidelines for GPIO device tree bindings trying to get things a bit
more strict with the advent of combined device properties
- Suspend/resume support for the MVEBU driver
- A slew of minor fixes and improvements"

The pin controllers of Exynos4415 are similar to Exynos4412, but certain differences cause the need to create separate driver data for it. This patch adds pin controller and bank descriptor arrays to the driver to support the new SoC.

Exynos7 uses different offsets for wakeup interrupt configuration registers. So a new irq_chip instance for Exynos7 wakeup interrupts is added. The irq_chip selection is now based on the wakeup interrupt controller compatible string.

Adding a irq_chip field to the samsung_pin_bank struct helps in consolidating the irq domain callbacks for external gpio and wakeup interrupt controllers. The exynos_wkup_irqd_ops and exynos_gpio_irqd_ops have now been merged into a single exynos_eint_irqd_ops.
