When a device uses the GIC as its interrupt controller and generates
SPIs, only the values 1 (edge rising) and 4 (level high) are legal.
Anything else is just plain wrong (can't be programmed into the HW),
and leads to aborted driver probes (USB doesn't work with 4.8-rc1
on a Dragonboard 410C).

The modem boot authenticator needs space to play in, this is supposed to

We can't initialize the list head on deletion as this causes the node to
point to itself, which causes an infinite loop if vmd_irq() happens to be
servicing that node.
The list initialization was trying to fix a bug from multiple calls to
disable the same IRQ. Fix this instead by having the VMD driver track if
the interrupt is enabled.

Commit e41f501d39 ("vmlinux.lds: account for destructor sections")
added '.text.exit' to EXIT_TEXT which is discarded at link time by default.
This breaks compilation of UML:
`.text.exit' referenced in section `.fini_array' of
/usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o):
defined in discarded section `.text.exit' of
/usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/libc.a(sdlerror.o)
Apparently UML doesn't want to discard exit text, so let's place all EXIT_TEXT
sections in .exit.text.

The pinctrl driver is essential for the Allwinner SoCs to work.
Add the driver's config symbol to the Kconfig entry to always compile
it in. We can't use the arm approach to make the _driver's_ Kconfig
symbol def_bool, because we lack the MACH_* symbols in arm64.
That line was in the original pinctrl driver patch, but got removed
to avoid the dependency on the Kconfig patch [1].
Also add the general PINCTRL symbol, which isn't selected automatically
for the same reason.

The davinci boards don't have their clocks in DT yet and getting a clock
will fail, unless registering them as clk_lookups. This registers the
aemif clock for the ti-aemif memory driver.
The current aemif lookup entry resolving to the same clock:
'CLK(NULL, "aemif", &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward
compatibility.
Currently the davinci boards only configure the AEMIF in case of non-DT
boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via
the ti-aemif memory driver code.

Since the non-secure copies of banked registers lack architecturally
defined reset values, there is no actual guarantee when entering in Hyp
from secure-only firmware that the Non-Secure PL1 state will look the
way that kernel entry (in particular the decompressor stub) expects.
So far, we've been getting away with it thanks to implementation details
of ARMv7 cores and/or bootloader behaviour, but for the sake of forwards
compatibility let's try to ensure that we have a minimally sane state
before dropping down into it.

Since we switched to use pxa_timer, we need to provide the OSTIMER0
clock. However, as the clock is initialised early, we need to provide
the clock early as well, so that pxa_timer can find it. Adding the
clock to the clkdev table at core_initcall() time is way too late.
Move the initialisation earlier.
