2016-08-15pci: tegra: port to standard clock/reset/pwr domain APIsStephen Warren
Tegra186 supports the new standard clock, reset, and power domain APIs. Older Tegra SoCs still use custom APIs. Enhance the Tegra PCIe driver so that it can operate with either set of APIs. On Tegra186, the BPMP handles all aspects of PCIe PHY (UPHY) programming. Consequently, this logic is disabled too.

2016-08-15i2c: add Tegra186 BPMP driverStephen Warren
On Tegra186, some I2C controllers are directly controlled by the main CPU, whereas others are controlled by the BPMP, and can only be accessed by the main CPU via IPC requests to the BPMP. This driver covers the latter case.

2016-08-15misc: add Tegra BPMP driverStephen Warren
The Tegra BPMP (Boot and Power Management Processor) is a separate auxiliary CPU embedded into Tegra to perform power management work, and controls related features such as clocks, resets, power domains, PMIC I2C bus, etc. This driver provides the core low-level communication path by which feature-specific drivers (such as clock) can make requests to the BPMP. This driver is similar to an MFD driver in the Linux kernel. It is unconditionally selected by CONFIG_TEGRA186 since virtually any Tegra186 build of U-Boot will need the feature.

2016-08-12fdt: allow fdtdec_get_addr_size_*() to translate addressesStephen Warren
Some code may want to read reg values from DT, but from nodes that aren't associated with DM devices, so using dev_get_addr_index() isn't appropriate. In this case, fdtdec_get_addr_size_*() are the functions to use. However, "translation" (via the chain of ranges properties in parent nodes) may still be desirable. Add a function parameter to request that, and implement it. Update all call sites to default to the original behaviour.

Commit 4b50369fb535 ("ARM: uniphier: create early page table at run-time") broke the ROM boot mode for PH1-sLD3 SoC, because the run-time page table creation requires the outer cache register access but the page table in the sLD3 Boot ROM does not straight-map virtual/physical addresses.
