2013-12-11ARM: tegra: document reset properties in DT bindingsStephen Warren
Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

2013-12-11ARM: tegra: add missing clock documentation to DT bindingsStephen Warren
Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties.

2013-05-17ARM: tegra: finalize USB EHCI and PHY bindingsVenu Byravarasu
The existing Tegra USB bindings have a few issues: 1) Many properties are documented as being part of the EHCI controller node, yet they apply more to the PHY device. They should be moved. 2) Some registers in PHY1 are shared with PHY3, and hence PHY3 needs a reg entry to point at PHY1's register space. We can't assume the PHY1 driver is present, so the PHY3 driver will directly access those registers. 3) The list of clocks required by the PHY was missing some required entries. 4) UTMI PHY Timing parameters are added 5) VBUS control is now specified using a regulator rather than a plain GPIO 6) Added nvidia,is-wired property to indicate whether the device is hard wired on the board, or pluggable. This patch fixes the binding definition to resolve these issues. Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-01-28ARM: tegra: add DT nodes for Tegra USB PHYVenu Byravarasu
Add DT nodes for Tegra USB PHY along with related documentation. Also added a phandle property to controller DT node, for referring to connected PHY instance. Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-01-28ARM: tegra: Add new DT property to USB node.Venu Byravarasu
As Tegra USB host driver is using instance number for resetting PORT0 twice, adding a new DT property for handling this. Signed-off-by: Venu Byravarasu <vbyravarasu@nvidia.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-06-11dt: name all Tegra binding docs consistentlyStephen Warren
Rename all Tegra binding documentation according to the first or primary compatible value they describe. This provides a clear naming scheme for the files, and prevents any naming conflicts should future SoC versions require their own binding. Signed-off-by: Stephen Warren <swarren@nvidia.com>
