arm/dt: tegra devicetree support Everything required to populate NVIDIA Tegra devices from the device tree. This patch adds a new DT_MACHINE_DESC() which matches against a tegra20 device tree. So far it only registers the on-chip devices, but it will be refined in follow on patches to configure clocks and pin IO from the device tree also.

ARM: dt: tegra seaboard: configure I2C2 pinmux The I2C2 controller can be routed to either pingroup DDC or PTA. Seaboard actually uses this as an I2C bus mux, and devices are connected to both pingroups. This change statically assigns the I2C2 controller to pingroup PTA, so that on-board devices can be accessed. The DDC pingroup is used for EDID/DDC accesses which are not yet required, given the absence of any Tegra graphics support. I2C muxing will be supported later.

ARM: tegra: seaboard: add EMC table to device tree Timings for the T25 version of seaboard, only one memory manufacturer and timing table (two speeds). Signed-off-by: Olof Johansson <olof@lixom.net>

ARM: dt: tegra: sort nodes based on bus order 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: tegra: add USB ULPI PHY reset GPIO to device tree ULPI PHYs have a reset signal, and different boards use a different GPIO for this task. Add a property to device tree to represent this. I'm not sure if adding this property to the EHCI controller node is entirely correct; perhaps eventually we should have explicit separate nodes for the various PHYs. However, we don't have that right now, so this binding seems like a reasonable choice.

arm/dt: tegra devicetree support Everything required to populate NVIDIA Tegra devices from the device tree. This patch adds a new DT_MACHINE_DESC() which matches against a tegra20 device tree. So far it only registers the on-chip devices, but it will be refined in follow on patches to configure clocks and pin IO from the device tree also.
