2012-12-13Merge tag 'multiplatform' of ↵Linus Torvalds1-0/+23
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform conversion patches from Olof Johansson: "Here are more patches in the progression towards multiplatform, sparse irq conversions in particular. Tegra has a handful of cleanups and general groundwork, but is not quite there yet on full enablement. Platforms that are enabled through this branch are VT8500 and Zynq. Note that i.MX was converted in one of the earlier cleanup branches as well (before we started a separate topic for multiplatform). And both new platforms for this merge window, sunxi and bcm, were merged with multiplatform support enabled." Fix up conflicts mostly as per Olof. * tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (29 commits) ARM: zynq: Remove all unused mach headers ARM: zynq: add support for ARCH_MULTIPLATFORM ARM: zynq: make use of debug_ll_io_init() ARM: zynq: remove TTC early mapping ARM: tegra: move debug-macro.S to include/debug ARM: tegra: don't include iomap.h from debug-macro.S ARM: tegra: decouple uncompress.h and debug-macro.S ARM: tegra: simplify DEBUG_LL UART selection options ARM: tegra: select SPARSE_IRQ ARM: tegra: enhance timer.c to get IO address from device tree ARM: tegra: enhance timer.c to get IRQ info from device tree ARM: timer: fix checkpatch warnings ARM: tegra: add TWD to device tree ARM: tegra: define DT bindings for and instantiate RTC ARM: tegra: define DT bindings for and instantiate timer clocksource/mtu-nomadik: use apb_pclk clk: ux500: Register mtu apb_pclocks ARM: plat-nomadik: convert platforms to SPARSE_IRQ mfd/db8500-prcmu: use the irq_domain_add_simple() mfd/ab8500-core: use irq_domain_add_simple() ...

2012-11-16ARM: tegra: add TWD to device treeStephen Warren1-0/+6
This will allow timer.c to use twd_local_timer_of_register(), and hence not need to hard-code the TWD address or IRQ. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-11-16ARM: tegra: define DT bindings for and instantiate RTCStephen Warren1-0/+6
The Tegra RTC maintains seconds and milliseconds counters, and five alarm registers. The alarms and other interrupts may wake the system from low-power state. Define a DT binding for this HW module, and add the module into the Tegra device tree files. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-11-16ARM: tegra: define DT bindings for and instantiate timerStephen Warren1-0/+11
The Tegra timer provides a number of 29-bit timer channels, a single 32-bit free running counter, and in the Tegra30 variant, 5 watchdog modules. The first two channels may also trigger a legacy watchdog reset. Define a DT binding for this HW module, and add the module into the Tegra device tree files.

2012-09-20ARM: tegra: dts: Add pwm labelThierry Reding1-1/+1
PWM devices can be referenced in the DT by phandle and per-chip index. In order for this to work properly, the PWM controller needs to have a label attached to it. Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-07-30Merge branch 'for-3.6' of git://gitorious.org/linux-pwm/linux-pwmLinus Torvalds1-0/+6
Pull PWM subsystem from Thierry Reding: "The new PWM subsystem aims at collecting all implementations of the legacy PWM API and to eventually replace it completely. The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann <arnd@arndb.de>: "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."

2012-05-14ARM: dt: tegra: invert status=disable vs status=okayStephen Warren1-0/+19
In tegra*.dtsi, set status="disable" for all HW modules that the board design may choose not to use. Update all boards to specifically enable any of those modules that are useful by setting status="okay". This makes board files say which features they do use, rather than which they don't, which feels more logical. It also makes the .dts files slightly smaller, at least for existing content.

2012-05-14ARM: dt: tegra: sort nodes based on bus orderStephen Warren1-89/+89
Sort the nodes according to the following rules: * First, any overrides for properties or nodes created by included files, in the order they appeared in the include file. * Second, any nodes with a reg property, in numerical order. * Third, any nodes without a reg property, in alphabetical order of node name. The second sorting rule at least will probably help if/when we need to explicitly insert nodes for the various busses in Tegra; that will just be an indentation change rather than also a node re-ordering.

2012-02-06gpio: tegra: Dynamically allocate IRQ base, and support DTStephen Warren1-0/+2
Enhance the driver to dynamically allocate the base IRQ number, and create an IRQ domain for itself. The use of an IRQ domain ensures that any device tree node interrupts properties are correctly parsed. Describe interrupt-related properties in the device tree binding docs, and the contents of "child" node interrupts property. Update tegra*.dtsi to specify the required interrupt-related properties. Finally, remove the definition of TEGRA_GPIO_TO_IRQ; this macro no longer gives correct results since the IRQ numbers for GPIOs are dynamically allocated.
