This patch rolls up several cleanup patches.
1. Some unnecessarily verbose variable names are used in several clock.c
functions; clean these up per CodingStyle.
2. Remove omap2_get_clksel() and just use clk->clksel_reg and
clk->clksel_mask directly.
3. Get rid of void __iomem * usage in omap2_clksel_get_src_field.
Prepend the function name with an underscore to highlight that it is a
static function.

[ARM] OMAP3 clock: disable DPLL autoidle while waiting for DPLL to lock
During _omap3_noncore_dpll_lock(), if a DPLL has no active downstream
clocks and DPLL autoidle is enabled, the DPLL may never lock, since it
will enter autoidle immediately. To resolve this, disable DPLL
autoidle while locking the DPLL, and unconditionally wait for the DPLL
to lock. This fixes some bugs where the kernel would hang when returning
from retention or return the wrong rate for the DPLL.

[ARM] OMAP3 clock: avoid invalid FREQSEL values during DPLL rate rounding
The DPLL FREQSEL jitter correction bits are set based on a table in
the 34xx TRM, Table 4-38, according to the DPLL's internal clock
frequency "Fint." Several Fint frequency ranges are missing from this
table. Previously, we allowed these Fint frequency ranges to be
selected in the rate rounding code, but did not change the FREQSEL bits.
Correspondence with the OMAP hardware team indicates that Fint values
not in the table should not be used. So, prevent them from being
selected during DPLL rate rounding. This removes warnings and also
can prevent the chip from locking up.
The first pass through the rate rounding code will update the DPLL max
and min dividers appropriately, so later rate rounding passes will run
faster than the first.

[ARM] OMAP3 clock: optimize DPLL rate rounding algorithm
The previous DPLL rate rounding algorithm counted the divider (N) down

tolerance, and lower N values are more power-efficient, we can often
bypass several iterations through the loop by counting N upwards from
1.

[ARM] OMAP: wait for pwrdm transition after clk_enable()
Enabling clock in a disabled power domain causes the power domain to be
turned on. However, the power transition is not always finished when
clk_enable() returns and this randomly crashes the kernel when an
interrupt happens right after the clk_enable, and the kernel tries to
read the irq status register for that domain.
Why the irq status register is inaccessible, I don't know. Also it
doesn't seem to be related to the module being not powered up, but to
the transition itself.
The same could perhaps happen after clk_disable also, but I have not
witnessed that.
The problem affects at least dss, cam and sgx clocks.
This change waits for the transition to be finished before returning

that it reflects the timer programming cost. A write to the timer
device will be usually posted, but it takes roughly 3 cycles before
it is effective. If the timer is reprogrammed before that, the CPU
will stall until the previous write completes. This was pointed out by
Richard Woodruff.
Since the lower bound for min_delta_ns is 1000, the change is visible
only with tick rates less than 3 MHz.
Also note that the old value is incorrect for 32 kHz also due to
a rounding error, and it can cause the timer queue to hang (due to

[ARM] 5366/1: fix shared memory coherency with VIVT L1 + L2 caches
When there are multiple L1-aliasing userland mappings of the same physical
page, we currently remap each of them uncached, to prevent VIVT cache
aliasing issues. (E.g. writes to one of the mappings not being immediately
visible via another mapping.) However, when we do this remapping, there
could still be stale data in the L2 cache, and an uncached mapping might
bypass L2 and go straight to RAM. This would cause reads from such
mappings to see old data (until the dirty L2 line is eventually evicted.)
This issue is solved by forcing a L2 cache flush whenever the shared page
is made L1 uncacheable.
Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But
Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding
for XSc3 doesn't appear to work in practice.

smackfs load append mode fix
Given just how hard it is to find the code that uses MAY_APPEND
it's probably not a big surprise that this went unnoticed for so
long. The Smack rules loading code is incorrectly setting the
MAY_READ bit when MAY_APPEND is requested.

USB: Driver for Freescale QUICC Engine USB Host Controller
This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.
Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.
This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.

This patch adds an unusual_devs entry for a Sony Ericsson modem. Like many

At this time usb_modeswitch does not work with this device.
