2014-05-15ARM: EXYNOS: Map SYSRAM through generic DT bindingsSachin Kamat1-0/+18
Instead of hardcoding the SYSRAM details for each SoC, pass this information through device tree (DT) and make the code SoC agnostic. Generic DT SRAM bindings are used for achieving this.

Pull late ARM Exynos multiplatform changes from Arnd Bergmann: "These continue the multiplatform support for exynos, adding support for building most of the essential drivers (clocksource, clk, irqchip) when combined with other platforms. As a result, it should become really easy to add full multiplatform exynos support in 3.11, although we don't yet enable it for 3.10. The changes were not included in the earlier multiplatform series in order to avoid clashes with the other Exynos updates.

We need to define two more pmus for this type board. However, supporting arm-pmu for the exynos4412 will handle it later because there is no dts support for 4412 based board.

2012-10-15pinctrl: samsung: Use per-bank IRQ domain for wake-up interruptsTomasz Figa1-7/+1
This patch reworks wake-up interrupt handling in pinctrl-exynos driver, so each pin bank, which provides wake-up interrupts, has its own IRQ domain. Information about whether given pin bank provides wake-up interrupts, how many and whether they are separate or muxed are parsed from device tree. It gives following advantages: - interrupts can be specified in device tree in a more readable way, e.g. : device { /* ... */ interrupt-parent = <&gpx2>; interrupts = <4 0>; /* ... */ }; - the amount and layout of interrupts is not hardcoded in the code anymore, but defined in SoC-specific structure - bank and pin of each wake-up interrupt can be easily identified, to allow operations, such as setting the pin to EINT function, from irq_set_type() callback Signed-off-by: Tomasz Figa <t.figa@samsung.com> Reviewed-by: Kyungmin Park <kyungmin.park@samsung.com> Acked-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-10-15pinctrl: exynos: Use one IRQ domain per pin bankTomasz Figa1-4/+0
Instead of registering one IRQ domain for all pin banks of a pin controller, this patch implements registration of per-bank domains. At a cost of a little memory overhead (~2.5KiB for all GPIO interrupts of Exynos4x12) it simplifies driver code and device tree sources, because GPIO interrupts can be now specified per banks. Example: device { /* ... */ interrupt-parent = <&gpa1>; interrupts = <3 0>; /* ... */ }; Signed-off-by: Tomasz Figa <t.figa@samsung.com> Reviewed-by: Kyungmin Park <kyungmin.park@samsung.com> Acked-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
