* ARM: dt: tegra: invert status=disable vs status=okayStephen Warren2012-05-141-0/+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.

* ARM: dt: tegra: sort nodes based on bus orderStephen Warren2012-05-141-89/+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.

* ARM: dt: tegra: format regs properties consistentlyStephen Warren2012-05-141-3/+4
| | | | | | | | | | | Place each reg "entry" on its own line, and wrap the whole list in <> rather than each individual entry. The convention chosen here is slightly arbitrary, but is not consistent throughout all Tegra files. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Olof Johansson <olof@lixom.net>

* | gpio: tegra: Dynamically allocate IRQ base, and support DTStephen Warren2012-02-071-0/+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.

* ARM: dt: Add binding for Tegra PMCStephen Warren2012-02-071-0/+5
| | | | | | | | | | | The Tegra PMC (Power Management Controller) interfaces with an external PMU (Power Management Unit), and controls wake-up from sleep modes.
