This implements a virtual clock used to abstract away
all the steps needed in order to change the ARM clock,
so we don't have to push all this clock handling into
the cpufreq driver.
While it will be used for i.MX53 at first it is generic
enough to be used on i.MX6 later on.

Add the ARM Global Timer as clocksource/scheduler clock option and
use it as default scheduler clock. This leaves the PIT timer for
other users e.g. the secondary Cortex-M4 core. Also, the Global Timer
has double the precission (running at pheripheral clock compared to
IPG clock) and a 64-bit incrementing counter register. We still keep
the PIT timer as an secondary option in case the ARM Global Timer is
not available.

As the DDR/IO and MMDC setting are different on LPDDR2 and DDR3,
we used cpu type to decide how to do these settings in suspend
before which is NOT flexible, take i.MX6SL for example, although
it has LPDDR2 on EVK board, but users can also use DDR3 on other
boards, so it is better to read the DDR type from MMDC then decide
how to do related settings.

The i.MX fixes for 3.18, 2nd round:
- Fix a regression on Vybrid platform which is caused by commit
dc4805c2e7 (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3
driver), and results in a missing configuration on PLL clocks.
- Fix a regression with i.MX defconfig files where CONFIG_SPI option
gets lost accidentally.
ext4_ext_remove_space() can incorrectly free a partial_cluster if
EAGAIN is encountered while truncating or punching. Extent removal
should be retried in this case.
It also fails to free a partial cluster when the punched region begins
at the start of a file on that unaligned cluster and where the entire
file has not been punched. Remove the requirement that all blocks in
the file must have been freed in order to free the partial cluster.

Add some casts and rearrange a few statements for improved readability.

The fix in commit ad6599ab3a ("ext4: fix premature freeing of
partial clusters split across leaf blocks"), intended to avoid
dereferencing an invalid extent pointer when determining whether a
partial cluster should be freed, wasn't quite good enough. Assure that
at least one extent remains at the start of the leaf once the hole has
been punched. Otherwise, the pointer to the extent to the right of the
hole will be invalid and a partial cluster will be incorrectly freed.
Set partial_cluster to 0 when we can tell we've hit the left edge of
the punched region within the leaf. This prevents incorrect freeing
of a partial cluster when ext4_ext_rm_leaf is called one last time
during extent tree traversal after the punched region has been removed.
Adjust comments to reflect code changes and a correction. Remove a bit
of dead code.

The partial_cluster variable is not always initialized correctly when
hole punching on bigalloc file systems. Although commit c063449394
("ext4: fix partial cluster handling for bigalloc file systems")
addressed the case where the right edge of the punched region and the
next extent to its right were within the same leaf, it didn't handle
the case where the next extent to its right is in the next leaf. This
causes xfstest generic/300 to fail.
Fix this by replacing the code in c0634493922 with a more general
solution that can continue the search for the first cluster to the
right of the punched region into the next leaf if present. If found,
partial_cluster is initialized to this cluster's negative value.
There's no need to determine if that cluster is actually shared; we
simply record it so its blocks won't be freed in the event it does
happen to be shared.
Also, minimize the burden on non-bigalloc file systems with some minor
code simplification.

In rk3188 clock branches, spdif_pre gate was set to RK2928_CLKGATE_CON(13) bit 13.
This appears to be a copy-paste error because such a register does not exist.

The original FDB code submission wasn't correct and the code
wasn't enabled. This removes some dead code (can use the common kernel
code for fdb_del and fdb_dump) and correctly enables the fdb_add
function pointer.
The fdb_add functionality is important to i40e because it is needed
for a workaround to allow bridges to work correctly on the i40e
hardware.

commit 6d9939f651 (i2c: omap: split out [XR]DR

Set) get handled. 6d9939f651 code doesn't correspond to workaround provided by
errata.
According to errata ISR must filter out spurious RDR before data read not after.
ISR must read RXSTAT to get number of bytes available to read. Because RDR
could be set while there could no data in the receive FIFO.

When system is being suspended, if host device is not allowed to do wakeup,
xhci_suspend() needs to clear all root port wake on bits. Otherwise, some
platforms may generate spurious wakeup, even if PCI PME# is disabled.
The initial commit ff8cbf250b ("xhci: clear root port wake on bits"),
which also got into stable, turned out to not work correctly and had to
be reverted, and is now rewritten.

If a device is halted and reuturns a STALL, then the halted endpoint
needs to be cleared both on the host and device side. The host
side halt is cleared by issueing a xhci reset endpoint command. The device side
is cleared with a ClearFeature(ENDPOINT_HALT) request, which should
be issued by the device driver if a URB reruen -EPIPE.
Previously we cleared the host side halt after the device side was cleared.
To make sure the host side halt is cleared in time we want to issue the
reset endpoint command immedialtely when a STALL status is encountered.
Otherwise we end up not following the specs and not returning -EPIPE
several times in a row when trying to transfer data to a halted endpoint.
