03e61929c0 arm64: dts: rockchip: limit clock rate of MMC controllers for RK3328
150MHz is a fundamental limitation of RK3328 Soc, w/o this limitation,
eMMC, for instance, will run into 200MHz clock rate in HS200 mode, which
makes the RK3328 boards not always boot properly. By adding it in
rk3328.dtsi would also obviate the worry of missing it when adding new
boards.

f7edb451fa tracing/arm64: Have max stack tracer handle the case of return address after data
Most archs (well at least x86) store the function call return address on the
stack before storing the local variables for the function. The max stack
tracer depends on this in its algorithm to display the stack size of each
function it finds in the back trace.

Some archs (arm64), may store the return address (from its link register)
just before calling a nested function. There's no reason to save the link
register on leaf functions, as it wont be updated. This breaks the algorithm
of the max stack tracer.

Add a new define ARCH_FTRACE_SHIFT_STACK_TRACER that an architecture may set
if it stores the return address (link register) after it stores the
function's local variables, and have the stack trace shift the values of the
mapped stack size to the appropriate functions.

7109d817db arm64: dts: marvell: add DTS for Turris Mox
This adds support for the Turris Mox board from CZ.NIC.

Turris Mox is as modular router based on the Armada 3720 SOC (same as
EspressoBin).

The basic board can be extended by different modules.
If those are connected, U-Boot lets the kernel know via device-tree.

Since modules can be connected in different order and some modules can
be connected multiple times (up to three modules containing 8-port
ethernet switch in DSA configuration can be connected) we decided
against using device-tree overlays, because it got complicated rather
quickly. (For example the SFP module can be connected directly to the
CPU, or after a switch module. There are four cases and all would need
different SFP overlay. There are two types of switch modules (8-port
with pass-through and 4-port with no pass-through). For those we would
again need at least 6 more overlays.)

We therefore decided to put all the possibly connected devices in one
device-tree and disable them by default. When U-Boot finds out which
modules are connected, it fixes the loaded device-tree accordingly just
before boot. By Rob Herring's suggestion we also made it so that U-Boot
completely removes nodes which are disabled after this fixup.

03adcbd996 arm64: atomics: Use K constraint when toolchain appears to support it
The 'K' constraint is a documented AArch64 machine constraint supported
by GCC for matching integer constants that can be used with a 32-bit
logical instruction. Unfortunately, some released compilers erroneously
accept the immediate '4294967295' for this constraint, which is later
refused by GAS at assembly time. This had led us to avoid the use of
the 'K' constraint altogether.

Instead, detect whether the compiler is up to the job when building the
kernel and pass the 'K' constraint to our 32-bit atomic macros when it
appears to be supported.

b32baf91f6 arm64: lse: Make ARM64_LSE_ATOMICS depend on JUMP_LABEL
Support for LSE atomic instructions (CONFIG_ARM64_LSE_ATOMICS) relies on
a static key to select between the legacy LL/SC implementation which is
available on all arm64 CPUs and the super-duper LSE implementation which
is available on CPUs implementing v8.1 and later.

Unfortunately, when building a kernel with CONFIG_JUMP_LABEL disabled
(e.g. because the toolchain doesn't support 'asm goto'), the static key
inside the atomics code tries to use atomics itself. This results in a
mess of circular includes and a build failure:

In file included from ./arch/arm64/include/asm/lse.h:11,
                 from ./arch/arm64/include/asm/atomic.h:16,
                 from ./include/linux/atomic.h:7,

         ^~~~~~~~~~~

[ ... more of the same ... ]

Since LSE atomic instructions are not critical to the operation of the
kernel, make them depend on JUMP_LABEL at compile time.

Each power supply can achieve 0.69V to 1.05V using a single PWM

DVFS has been tested by running the arm64 cpuburn at [1] and cycling
between all the possible cpufreq translations of the cpu cluster and
checking the final frequency using the clock-measurer, script at [2].

3337cb5aea arm64: avoid using hard-coded registers for LSE atomics
Now that we have removed the out-of-line ll/sc atomics we can give
the compiler the freedom to choose its own register allocation.

Remove the hard-coded use of x30.

addfc38672 arm64: atomics: avoid out-of-line ll/sc atomics
When building for LSE atomics (CONFIG_ARM64_LSE_ATOMICS), if the hardware
or toolchain doesn't support it the existing code will fallback to ll/sc
atomics. It achieves this by branching from inline assembly to a function
that is built with special compile flags. Further this results in the
clobbering of registers even when the fallback isn't used increasing
register pressure.

Improve this by providing inline implementations of both LSE and
ll/sc and use a static key to select between them, which allows for the
compiler to generate better atomics code. Put the LL/SC fallback atomics
in their own subsection to improve icache performance.
