This device tree allows to boot, supports the panel,
framebuffer, touch screen, as well as some more peripherals.
Since there is a OMAP3530 based 600 MHz variant and a DM3730 based
1 GHz variant we must include this common device tree code
in one of two CPU specific device trees.

This patch adds missing dma DTS definitions for omap aes and sham drivers.
Without it kernel drivers do not work for device tree based booting
while it works for legacy booting on general purpose SoCs.
Note that further changes are still needed for high secure SoCs. But since
that never worked in legacy boot mode either, those will be sent separately.

Merge "Renesas ARM Based SoC da9063/da9210 Regulator Quirk for v4.1" from Simon Horman:
The r8a7790/lager and r8a7791/koelsch development boards have da9063 and
da9210 regulators. Both regulators have their interrupt request lines
tied to the same interrupt pin (IRQ2) on the SoC.
After cold boot or da9063-induced restart, both the da9063 and da9210
seem to assert their interrupt request lines. Hence as soon as one
driver requests this irq, it gets stuck in an interrupt storm, as it
only manages to deassert its own interrupt request line, and the other
driver hasn't installed an interrupt handler yet.
To handle this, install a quirk that masks the interrupts in both the
da9063 and da9210. This quirk has to run after the i2c master driver
has been initialized, but before the i2c slave drivers are initialized.
As it depends on i2c, select I2C if one of the affected platforms is
enabled in the kernel config.

OMAP4/5 has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.
This patch does just this, updating the DT files to actually
reflect what the HW provides.
BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

Support for the TI crossbar used on the DRA7 family of chips
is implemented as an ugly hack on the side of the GIC.
Converting it to stacked domains makes it slightly more
palatable, as it results in a cleanup.
Unfortunately, as the DT bindings failed to acknowledge the
fact that this is actually yet another interrupt controller
(the third, actually), we have yet another breakage. Oh well.
