irqchip: renesas-intc-irqpin: Add minimal runtime PM support
This is just enough to let pm_clk_*() enable the functional clock, and
manage it for suspend/resume, if present.
Before, it was assumed enabled by the bootloader or reset state.
To prevent the clock from being disabled while the module is needed for
wake-up, implement irq_chip.irq_set_wake(), which increments/decrements
the clock's enable_count when needed.

</quote>
As this issue is fairly widespread and involves at least three
different architectures, a possible solution is to add a new
handle_domain_irq entry point into the generic IRQ code that
the interrupt controller code can call.
This new function takes an irq_domain, and calls into irq_find_domain
inside the irq_{enter,exit} block. An additional "lookup" parameter is
used to allow non-domain architecture code to be replaced by this as well.
Interrupt controllers can then be updated to use the new mechanism.
This code is sitting behind a new CONFIG_HANDLE_DOMAIN_IRQ, as not all
architectures implement set_irq_regs (yes, mn10300, I'm looking at you...).

irqchip: hip04: Enable Hisilicon HiP04 interrupt controller
HiP04 GIC is the variate of ARM GICv2.
ARM GICv2 supports 8 cores. HiP04 GIC extends to support 16 cores. It
results that bit fields in GIC_DIST_TARGET & GIC_DIST_SOFTINT are
different from ARM GICv2. And the maximium IRQ is downgrade from 1020 to 510.
Since different register offset & bitfields definitation breaks
compartible with ARM GICv2, create a new hip04 irq driver.
And this driver is derived from irq-gic.c to support the Hisilicon HiP04
interrupt controller, which is similar to the GIC, but deviates at some
points. Support for power management, non-banked registers, cascaded
GICs (and multiple controllers in general) and bigLittle support has
been removed from the GIC driver.
Affinity related functions have been adjusted to match the Hisilicon

irqchip: keystone: Add irq controller ip driver
On Keystone SOCs, DSP cores can send interrupts to ARM
host using the IRQ controller IP. It provides 28 IRQ
signals to ARM. The IRQ handler running on HOST OS can
identify DSP signal source by analyzing SRCCx bits in
IPCARx registers. This is one of the component used by
the IPC mechanism used on Keystone SOCs.

at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.
And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).
So this patch does 3 things to get proper rfkill handling on these models:
1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.
2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1
3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.

thinkpad_acpi: Update mapping for F12 hotkey on *40 models to KEY_FILE
The new keyboard found on the *40 models is also being sold as a standalone
keyboard (with trackpoint):

This uses a standard HUT code for the F12 key with the 6 square boxes on it,
which gets mapped to KEY_FILE by the kernel. Change the mapping done of
identical laptop key done by thinkpad_acpi to also send KEY_FILE for
consistency.
