* ARM: tegra: harmony - Add +5V HDMI supplyThierry Reding2014-04-281-0/+12
| | | | | | | | This supply controls the +5V pin on the HDMI connector, which in turn is used by attached sinks to return the hotplug detect signal. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>

* ARM: tegra: set up /aliases entries for RTCsStephen Warren2013-12-181-0/+5
| | | | | | | | | | This ensures that the PMIC RTC provides the system time, rather than the on-SoC RTC, which is not battery-backed. tegra124-venice2.dts isn't touched yet since we haven't added any off- SoC RTC device to its device tree. Signed-off-by: Stephen Warren <swarren@nvidia.com>

* ARM: tegra: convert device tree files to use key definesLaxman Dewangan2013-12-161-110/+111
| | | | | | | | | | | | | Use key code macros for all key code refernced for keys. For tegra20-seaboard.dts and tegra20-harmony.dts: The key comment for key (16th row and 1st column) is KEY_KPSLASH but code is 0x004e which is the key code for KEY_KPPLUS. As there other key exist with KY_KPPLUS, I am assuming key code is wrong and comment is fine. With this assumption, I am keeping the key code as KEY_KPSLASH.

* ARM: tegra: fix node sort orderStephen Warren2013-12-161-92/+92
| | | | | | | | | | | | | | | For Tegra DT files, I've been attempting to keep the nodes sorted in the order: 1) Nodes with reg, in order of reg. 2) Nodes without reg, alphabetically. This patch fixes a few escapees that I missed:-( The diffs look larger than they really are, because sometimes when one node was moved up or down, diff chose to represent this as many other nodes being moved the other way!

* ARM: tegra: add missing unit addresses to DTStephen Warren2013-12-161-7/+7
| | | | | | | | | | DT node names should include a unit address iff the node has a reg property. For Tegra DTs at least, we were previously applying a different rule, namely that node names only needed to include a unit address if it was required to make the node name unique. Consequently, many unit addresses are missing. Add them. Signed-off-by: Stephen Warren <swarren@nvidia.com>

* ARM: tegra: convert device tree files to use GPIO definesStephen Warren2013-05-281-20/+26
| | | | | | | Use TEGRA_GPIO() macro to name all GPIOs referenced by GPIO properties, and some interrupts properties. Use standard GPIO flag defines too. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* ARM: tegra: use #include for all device treesStephen Warren2013-05-281-1/+1
| | | | | | | | | | | | | Replace /include/ (dtc) with #include (C pre-processor) for all Tegra DT files, so that gcc -E handles the entire include tree, and hence any of those files can #include some other file e.g. for constant definitions. This allows future use of #defines and header files in order to define names for various constants, such as the IDs and flags in GPIO specifiers. Use of those features will increase the readability of the device tree files. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* ARM: tegra: update device trees for USB binding reworkVenu Byravarasu2013-05-171-0/+9
| | | | | | | | | | | | | This patch updates all Tegra board files so that they contain all the properties required by the updated USB DT binding. Note that this patch only adds the new properties and does not yet remove the old properties, in order to maintain bisectability. The old properties will be removed once the driver has been updated to assume the new bindings.

* ARM: dt: tegra: harmony: add regulatorsLaxman Dewangan2012-09-141-0/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Harmony uses a TPS6586x regulator. Instantiate this, and hook up a couple of fixed GPIO-controlled regulators too. Based on Ventana regulator patch by Stephen Warren <swarren@nvidia.com> and converted to Harmony. swarren made the following changes: * Added ldo0 regulator configuration to device tree, and updated board-harmony-pcie.c for the new regulator name. * Fixed vdd_1v05's voltage from 10.5V to 1.05V. * Modified board-harmony-pcie.c to obtain the en_vdd_1v05 GPIO number at run-time from device tree instead of hard-coding it. * Removed board-harmony{-power.c,.h} now that they're unused. * Disabled vdd_1v05 regulator; the code in board-harmony-pcie.c hijacks this GPIO for now. This will be fixed when the PCIe driver is re- written as a driver. The code can't regulator_get("vdd_1v05") right now, because the vdd_1v05 regulator's probe gets deferred due to its supply being the PMIC, which gets probed after the regulator the first time around, and this dependency is only resolved by repeated probing, which happens when deferred_probe_initcall() is called, which happens in a late initcall, whose runtime order relative to harmony_pcie_init() is undefined, since that's also called from a late initcall. * Removed unused harmony_pcie_initcall().

* ARM: dt: tegra: rename board files to match SoCStephen Warren2012-06-201-0/+336
Most ARM ${board}.dts files are already named ${soc}-${board}.dts. This change modifies the Tegra board files to be named the same way for consistency. Once a related change is made in U-Boot, this will cause both U-Boot and the kernel to use the same names for the .dts files and SoC identifiers, thus allowing U-Boot's recently added "soc" and "board" environment variables to be used to construct the name of Tegra .dtb files, and hence allow board-generic U-Boot bootcmd scripts to be written.
