Merge "ARM: tegra: rework PCIe regulators" from Thierry Reding:

This branch reworks the set of regulators that the Tegra PCIe driver
uses, so that the driver and DT bindings more correctly model what's
really going on in HW. For backwards-compatibility the driver will
fallback to using the old set of regulators if the new ones can't be
found.

I've made this a separate branch in case it needs to be pulled into the
PCIe tree to resolve any conflicts.

This patch adds necessary DT nodes for pcie controllers and miphys for SPEAr13xx
SoCs.

SPEAr1310 has 3 PCIe ports and SPEAr1340 has 1, which are multiplexed with
ahci/sata pins. By default evaluation board of both controller works in ahci
mode. Because of this, these nodes are marked "disabled" by default.

In order to use pcie controller on evaluation boards do necessary modifications
on board and enable (By replacing "disabled" with "okay") pcie and miphy from
respective 'evb' dtsi file.

Phy specific initialization was previously done from spear1340.c, which isn't
required anymore as we have separate drivers for it. Remove it.

On the syscall tracing path, we call out to secure_computing() to allow
seccomp to check the syscall number being attempted. As part of this, a
SIGTRAP may be sent to the tracer and the syscall could be re-written by
a subsequent SET_SYSCALL ptrace request. Unfortunately, this new syscall
is ignored by the current code unless TIF_SYSCALL_TRACE is also set on
the current thread.

This patch slightly reworks the enter path of the syscall tracing code
so that we always reload the syscall number from
current_thread_info()->syscall after the potential ptrace traps.

to use memblock_get_current_limit for calculating the max_low pfn.
nommu targets never actually set a limit on memblock though which
means memblock_get_current_limit will just return the default

When a PL310 cache is used on a system that provides hardware
coherency, the outer cache sync operation is useless, and can be
skipped. Moreover, on some systems, it is harmful as it causes
deadlocks between the Marvell coherency mechanism, the Marvell PCIe
controller and the Cortex-A9.

To avoid this, this commit introduces a new Device Tree property
'arm,io-coherent' for the L2 cache controller node, valid only for the
PL310 cache. It identifies the usage of the PL310 cache in an I/O
coherent configuration. Internally, it makes the driver disable the
outer cache sync operation.

Note that technically speaking, a fully coherent system wouldn't
require any of the other .outer_cache operations. However, in
practice, when booting secondary CPUs, these are not yet coherent, and
therefore a set of cache maintenance operations are necessary at this
point. This explains why we keep the other .outer_cache operations and
only ->sync is disabled.

While in theory any write to a PL310 register could cause the
deadlock, in practice, disabling ->sync is sufficient to workaround
the deadlock, since the other cache maintenance operations are only
used in very specific situations.

Contrary to previous versions of this patch, this new version does not
simply NULL-ify the ->sync member, because the l2c_init_data
structures are now 'const' and therefore cannot be modified, which is
a good thing. Therefore, this patch introduces a separate
l2c_init_data instance, called of_l2c310_coherent_data.
