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().

There currently aren't bindings for the Tegra PCIe controller. Work on this is in progress, but not yet complete. Manually initialize PCIe when booting from device tree, in order to bring DT support to the same feature level as board files, which will in turn allow board files to be deprecated. PCIe on Harmony requires various regulators to be registered and enabled before initializing the PCIe controller. Note that since the I2C controllers are instantiated from DT, we must use i2c_new_device() to register the PMU rather than i2c_register_board_info().

The Harmony pinmux table is already set up to mux the PCIe signals onto the appropriate pin groups. Don't manually fiddle with the pinmux in the Harmony PCIe setup code. Merge note: This will have a merge conflict with Peter De Schrijver's "arm/tegra: prepare pinmux code for multiple tegra variants" due to context. When merging the two, make sure to also remove the include of <mach/pinmux-tegra20.h> that his patch added, since it's no longer needed after this patch.

This patch modifies the pinmux code to be useable for multiple tegra variants. Some tegra20 specific constants will be replaced by variables which will be initialized to the appropriate value at runtime.

On Harmony board PCI-e subsystem can be enabled only after certain voltage regulators are on. One of the regulators is an internal regulator on the PMIC and another one is controlled by a PMIC GPIO. Addition of the voltage control to the Harmony PCI-e initialization allows booting of kernel with CONFIG_TEGRA_PCI even if the PMIC driver is not loaded. In this case the PCI-e initialization will fail gracefully intead of hanging the system. Signed-off-by: NMike Rapoport <mike@compulab.co.il> Signed-off-by: NOlof Johansson <olof@lixom.net>
