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.

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

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

nodes) may still be desirable. Add a function parameter to request that,
and implement it. Update all call sites to default to the original

Commit 4b50369f ("ARM: uniphier: create early page table at

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.

The idea here is to check the current page table to determine if
it is a straight map table.  If not, adjust the outer cache register
base.
