request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().

The outer_disable() of Tegra's suspend code is open-coded now since
that helper produces spurious warning message about secondary CPUs being
online when CPU enters into LP2 from cpuidle. The secondaries are actually
halted by the cpuidle driver on entering into LP2 idle-state, but the
online status is not touched by the cpuidle. This fixes a storm of
warnings once LP2 idling state is enabled on Tegra30. The outer_disable()
helper has sanity checks for interrupts and secondary CPUs being disabled
and we are pretty confident about the interrupts state during of CPU
idling / system suspend. The rail-off status check is added in this patch
as equivalent for the "num_online_cpus() > 1".

Tegra PMC has blink control to output 32 kHz clock out to Tegra blink
pin. Blink pad DPD state and enable controls are part of Tegra PMC
register space.
Currently Tegra clock driver registers blink control by passing PMC
address and register offset to clk_register_gate which performs direct
PMC access during clk_ops and with this when PMC is in secure mode, any
access from non-secure world does not go through.
This patch adds blink control registration to the Tegra PMC driver using
PMC specific clock gate operations that use tegra_pmc_readl() and
tegra_pmc_writel() to support both secure mode and non-secure
mode PMC register access.

Tegra PMC has clk_out_1, clk_out_2, and clk_out_3 clocks and currently
these PMC clocks are registered by Tegra clock driver with each clock as
separate mux and gate clocks using clk_register_mux and clk_register_gate
by passing PMC base address and register offsets and PMC programming for
these clocks happens through direct PMC access by the clock driver.
With this, when PMC is in secure mode any direct PMC access from the
non-secure world does not go through and these clocks will not be
functional.
This patch adds these PMC clocks registration to pmc driver with PMC as
a clock provider and registers each clock as single clock.
clk_ops callback implementations for these clocks uses tegra_pmc_readl and
tegra_pmc_writel which supports PMC programming in both secure mode and

The Tegra30 CPUIDLE driver has intention to check whether primary CPU was
the last CPU that entered LP2 (CC6) idle-state, but that functionality
never got utilized because driver never supported the CC6 state for the
case where any secondary CPU is online. The new cpuidle driver will
properly support CC6 on Tegra30, including the case where secondary CPUs
are online, and that knowledge about what CPUs entered into CC6 won't be
needed at all because new driver will use different approach by making use
of the coupled idle-state and explicitly parking secondary CPUs before
entering into CC6. Thus this patch is just a minor cleanup change.

Pen-locking is meant to block CPU0 if CPU1 wakes up during of entering
into LP2 because of some interrupt firing up, preventing unnecessary LP2
enter that will be resumed immediately. Apparently this case doesn't
happen often in practice, I checked how often it takes place and found
that after ~20 hours of browsing web, managing email, watching videos and
idling (15+ hours) there is only a dozen of early LP2 entering abortions
and they all happened while device was idling. Thus let's remove the
pen-locking and make LP2 entering uninterruptible, simplifying code quite
a lot. This will also become very handy for the upcoming unified cpuidle
driver, allowing to have a common LP2 code-path across of different
hardware generations.

Removing attach_adapter from this driver caused a regression for at
least some machines. Those machines had the sensors described in their
DT, too, so they didn't need manual creation of the sensor devices. The
old code worked, though, because manual creation came first. Creation of
DT devices then failed later and caused error logs, but the sensors
worked nonetheless because of the manually created devices.
When removing attach_adaper, manual creation now comes later and loses
the race. The sensor devices were already registered via DT, yet with
another binding, so the driver could not be bound to it.
This fix refactors the code to remove the race and only manually creates
devices if there are no DT nodes present. Also, the DT binding is updated
to match both, the DT and manually created devices. Because we don't
know which device creation will be used at runtime, the code to start
the kthread is moved to do_probe() which will be called by both methods.

The plain reads are outside of jh->b_state_lock critical section which result
in data races. Fix them by adding pairs of READ|WRITE_ONCE().

Four small fixes. Three are in drivers for fairly obvious bugs. The
fourth is a set of regressions introduced by the compat_ioctl changes
because some of the compat updates wrongly replaced .ioctl instead of
.compat_ioctl.
