877dd4b1f7 ARM: configs: add a gemini defconfig
It makes sense to have a stripped-down defconfig for just Gemini, as
it is a pretty small platform used in NAS etc, and will use appended
device tree. It is also quick to compile and test. Hopefully this
defconfig can be a good base for distributions such as OpenWRT.

I plan to add in the config options needed for the different
variants of Gemini as we go along.

d5d332d3f7 devicetree: Move include prefixes from arch to separate directory
We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.

Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.

As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.

Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.

As a remedy, move the include link directories out of the architecture
trees into a common location. At the same time, they can now share one
directory and one dt-bindings/ link as well.

Fixes: 4027494ae6e3 ('ARM: dts: add arm/arm64 include symlinks')

bca5238816 ARM: dts: dra7: Reduce cpu thermal shutdown temperature
On dra7, as per TRM, the HW shutdown (TSHUT) temperature is hardcoded
to 123C and cannot be modified by SW. This means when the temperature
reaches 123C HW asserts TSHUT output which signals a warm reset.
This reset is held until the temperature goes below the TSHUT low (105C).

While in SW, the thermal driver continuously monitors current temperature
and takes decisions based on whether it reached an alert or a critical point.
The intention of setting a SW critical point is to prevent force reset by HW
and instead do an orderly_poweroff(). But if the SW critical temperature is
greater than or equal to that of HW then it defeats the purpose. To address
this and let SW take action before HW does keep the SW critical temperature
less than HW TSHUT value.

The value for SW critical temperature was chosen as 120C just to ensure
we give SW sometime before HW catches up.

We don't want to use the OTG controller block on this
platform as it limits host mode to high-speed. Instead
we rely on extcon framework to give us ID events for
dual-role mode detection.

b9cb2ba718 ARM: dts: Use - instead of @ for DT OPP entries for TI SoCs
Compiling the DT file with W=1, DTC warns like follows:

Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property

Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

8ebe5c541a ARM: dts: exynos: Remove MFC reserved buffers
During my research I found that some of the requirements for the memory
buffers for MFC v6+ devices were blindly copied from the previous (v5)
version and simply turned out to be excessive. The relaxed requirements
are applied by the recent patches to the MFC driver and the driver is
now fully functional even without the reserved memory blocks for all
v6+ variants. This patch removes those reserved memory nodes from all
boards having MFC v6+ hardware block.

661e6b02b5 KVM: arm: plug potential guest hardware debug leakage
Hardware debugging in guests is not intercepted currently, it means
that a malicious guest can bring down the entire machine by writing
to the debug registers.

This patch enable trapping of all debug registers, preventing the
guests to access the debug registers. This includes access to the
debug mode(DBGDSCR) in the guest world all the time which could
otherwise mess with the host state. Reads return 0 and writes are
ignored (RAZ_WI).

The result is the guest cannot detect any working hardware based debug
support. As debug exceptions are still routed to the guest normal
debug using software based breakpoints still works.

To support debugging using hardware registers we need to implement a
debug register aware world switch as well as special trapping for
registers that may affect the host state.

Let's not try our luck for much longer, and disable stack-protector
for code living at HYP.
