The changes depend on earlier platform specific updates and touch the usual platforms: omap, exynos, tegra, mxs, mvebu and davinci." * tag 'dt-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (169 commits) ARM: exynos: dts: cros5250: add EC device ARM: dts: Add sbs-battery for exynos5250-snow ARM: dts: Add i2c-arbitrator bus for exynos5250-snow ARM: dts: add mshc controller node for Exynos4x12 SoCs ARM: dts: Add chip-id controller node on Exynos4/5 SoC ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree ARM: davinci: da850-evm: add SPI flash support ARM: davinci: da850: override SPI DT node device name ARM: davinci: da850: add SPI1 DT node spi/davinci: add DT binding documentation spi/davinci: no wildcards in DT compatible property ARM: dts: mvebu: Convert mvebu device tree files to 64 bits ARM: dts: mvebu: introduce internal-regs node ARM: dts: mvebu: Convert all the mvebu files to use the range property ARM: dts: mvebu: move all peripherals inside soc ARM: dts: mvebu: fix cpus section indentation ARM: davinci: da850: add EHRPWM & ECAP DT node ARM/dts: OMAP3: fix pinctrl-single configuration ARM: dts: Add OMAP3430 SDP NOR flash memory binding ARM: dts: Add NOR flash bindings for OMAP2420 H4 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | #interrupt-cells description The binding documentation for the OMAP GPIO controller has the "#interrupt-cells" property listed before "#interrupt-controller" property but its description after. This is confusing so we move "#interrupt-cells" after the "interrupt-controller" property so is followed by its description. While being there, change the properties order to be consistent with Documentation/devicetree/bindings/interrupt-controller/interrupts.txt and Documentation/devicetree/bindings/gpio/gpio.txt. According with these docs, the order of the properties for a gpio-omap device node should be: gpio-controller; #gpio-cells = <2>; interrupt-controller; #interrupt-cells = <2>; Reported-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Acked-by: Jon Hunter <jon-hunter@ti.com> Signed-off-by: Benoit Cousson <benoit.cousson@linaro.org>
* | gpio/omap: force restore if context loss is not detectableJon Hunter2013-04-101-2/+5
|/ | | | | | | | | | | | | | | | | | 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.

* gpio/omap: Add DT support to GPIO driverBenoit Cousson2012-03-051-0/+36
Adapt the GPIO driver to retrieve information from a DT file. Allocate the irq_base dynamically and rename bank->virtual_irq_start to bank->irq_base. Change irq_base type to int instead of u16 to match irq_alloc_descs output. Add documentation for GPIO properties specific to OMAP.
