This patch splits rk3399-rockpro64 dts file to 2 files for v2 and
v2.1 boards.
Both v2 and v2.1 boards can use almost same settings but we find a
difference in I2C address of audio CODEC ES8136.

The min/max value of vdd_log is decide by pwm IO voltage and its
resistors, the rk3399-firefly board's pwm regulator circuit is designed
for IO voltage at 1.8V, while the board actually use 3.0V for IO, which
at last lead to the min-microvolt to '430mV' instead of '800mV'.

On rk3399 vdd_log shall not exceed 1.0 V. On rk3399-roc-pc
vdd_log is presently 1118 mV. Fix by setting the min voltage
of the respective pwm-regulator down to 450 mV.
This results in a vdd_log of 953 mV.
Specify the supply to silence warning.

Working with rootfs on two 128GB mmcs on rk3399-roc-pc.
One (mmc name 128G72, one screw hole) works fine in HS400 mode.
Other (mmc name DJNB4R, firefly on pcb, two screw holes) gets lots of
mmc1: "running CQE recovery", even hangs with damaged fs,
when running under heavy load, e.g. compiling kernel.
Both run fine with HS200.
Disabling CQ with patch mmc: core: Add MMC Command Queue Support kernel parameter [0] did not help.
[0] 54e264154b
Therefore I propose to disable HS400 mode on roc-pc for now.

It looks like the px30 is running unstable at this 408MHz operating point.
This shows in stalled threads and other big numbers of kernel exception.
At 600MHz and above it instead works stable and as expected. As the 408MHz
point doesn't even decrease the voltage compared to 600MHz, just drop this
408MHz operating point for now.

Expand the power tree description with the 0V9 and 1V8 supplies to the
RK3399 PCIe block. The NanoPis M4 and NEO4 just route 2 lanes to the
user expansion pins, so there's not much more to say at the board level
for them; NanoPC-T4 has a standard M.2 connector so we can at least
claim the 3.3V supply to that too.

Although it appeared to follow logically from the bindings, apparently
the thermal framework can't properly cope with a single cooling device
being shared between multiple maps. The CPU zone is probably easier to
overheat, so remove the references to the (optional) fan from the GPU
cooling zone to avoid things getting confused. Hopefully GPU-intensive
tasks will leak enough heat across to the CPU zone to still hit the
fan trips before reaching critical GPU temperatures.

A few commits splitting the KASAN instrumented bitops header in
three, to match the split of the asm-generic bitops headers.
This is needed on powerpc because we use asm-generic/bitops/non-atomic.h,
for the non-atomic bitops, whereas the existing KASAN instrumented
bitops assume all the underlying operations are provided by the arch
as arch_foo() versions.

Commit fd7d58f0db ("ARM: multi_v7_defconfig: renormalize based on recent
additions") removed explicit enable line for CONFIG_DEBUG_FS, because
that feature has been selected by other enabled options: CONFIG_TRACING,
which were enabled by CONFIG_PERF_EVENTS.
In meantime, commit 0e4a459f56 ("tracing: Remove unnecessary DEBUG_FS
dependency") removed the dependency between CONFIG_DEBUG_FS and
CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds.
Enable it again explicitly, as debugfs support is essential for various
automated testing tools.

When I tweaked the ftrace entry assembly in commit:
3b23e4991f ("arm64: implement ftrace with regs")
... my ifdeffery tweaks left ftrace_graph_caller undefined for
CONFIG_DYNAMIC_FTRACE && CONFIG_FUNCTION_GRAPH_TRACER when ftrace is
based on mcount.
The kbuild test robot reported that this issue is detected at link time:
| arch/arm64/kernel/entry-ftrace.o: In function `skip_ftrace_call':
| arch/arm64/kernel/entry-ftrace.S:238: undefined reference to `ftrace_graph_caller'
| arch/arm64/kernel/entry-ftrace.S:238:(.text+0x3c): relocation truncated to fit: R_AARCH64_CONDBR19 against undefined symbol

| arch/arm64/kernel/entry-ftrace.S:243:(.text+0x54): relocation truncated to fit: R_AARCH64_CONDBR19 against undefined symbol
| `ftrace_graph_caller'
This patch fixes the ifdeffery so that the mcount version of
ftrace_graph_caller doesn't depend on CONFIG_DYNAMIC_FTRACE. At the same
time, a redundant #else is removed from the ifdeffery for the
patchable-function-entry version of ftrace_graph_caller.

compute_layout() is invoked as part of an alternative fixup under
stop_machine(). This function invokes get_random_long() which acquires a
sleeping lock on -RT which can not be acquired in this context.
Rename compute_layout() to kvm_compute_layout() and invoke it before
stop_machine() applies the alternatives. Add a __init prefix to
kvm_compute_layout() because the caller has it, too (and so the code can be
discarded after boot).

__range_ok(), invoked from access_ok(), clears the tag of the user
address only if CONFIG_ARM64_TAGGED_ADDR_ABI is enabled and the thread
opted in to the relaxed ABI. The latter sets the TIF_TAGGED_ADDR thread
flag. In the case of asynchronous I/O (e.g. io_submit()), the
access_ok() may be called from a kernel thread. Since kernel threads
don't have TIF_TAGGED_ADDR set, access_ok() will fail for valid tagged
user addresses. Example from the ffs_user_copy_worker() thread:
use_mm(io_data->mm);
ret = ffs_copy_to_iter(io_data->buf, ret, &io_data->data);
unuse_mm(io_data->mm);
Relax the __range_ok() check to always untag the user address if called
in the context of a kernel thread. The user pointers would have already
been checked via aio_setup_rw() -> import_{single_range,iovec}() at the
time of the asynchronous I/O request.

__arch_get_hw_counter() should check clock_mode to see if it can access
CNTVCT. With the conversion to unified vDSO this check has been left out.
This causes on imx v6 and v7 (imx_v6_v7_defconfig) and other platforms to
hang at boot during the execution of the init process as per below:

Commit ca74b316df ("arm: Use common cpu_topology structure and
functions.") changed cpu_coregroup_mask() from the ARM32 specific
implementation in arch/arm/include/asm/topology.h to the one shared
with ARM64 and RISCV in drivers/base/arch_topology.c.
Currently on ARM32 (TC2 w/ CONFIG_SCHED_MC) the task scheduler setup
code (w/ CONFIG_SCHED_DEBUG) shows this during CPU hotplug:
ERROR: groups don't span domain->span
It happens to CPUs of the cluster of the CPU which gets hot-plugged
out on scheduler domain MC.
Turns out that the shared cpu_coregroup_mask() requires that the
hot-plugged CPU is removed from the core_sibling mask via
remove_cpu_topology(). Otherwise the 'is core_sibling subset of
cpumask_of_node()' doesn't work. In this case the task scheduler has to
deal with cpumask_of_node instead of core_sibling which is wrong on
scheduler domain MC.
e.g. CPU3 hot-plugged out on TC2 [cluster0: 0,3-4 cluster1: 1-2]:
cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,3-4
^
should be:
cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,4
Add remove_cpu_topology() to __cpu_disable() to remove the CPU from the
topology masks in case of a CPU hotplug out operation.
At the same time tweak store_cpu_topology() slightly so it will call
update_siblings_masks() in case of CPU hotplug in operation via
secondary_start_kernel()->smp_store_cpu_info().
This aligns the ARM32 implementation with the ARM64 one.
Guarding remove_cpu_topology() with CONFIG_GENERIC_ARCH_TOPOLOGY is
necessary since some Arm32 defconfigs (aspeed_g5_defconfig,
milbeaut_m10v_defconfig, spear13xx_defconfig) specify an explicit
# CONFIG_ARM_CPU_TOPOLOGY is not set
w/ ./arch/arm/Kconfig: select GENERIC_ARCH_TOPOLOGY if ARM_CPU_TOPOLOGY

Pull ARM SoC driver updates from Olof Johansson:
"Various driver updates for platforms:
- A larger set of work on Tegra 2/3 around memory controller and
regulator features, some fuse cleanups, etc..
- MMP platform drivers, in particular for USB PHY, and other smaller
additions.
- Samsung Exynos 5422 driver for DMC (dynamic memory configuration),
and ASV (adaptive voltage), allowing the platform to run at more
optimal operating points.
- Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas
- Clock/reset control driver for TI/OMAP
- Meson-A1 reset controller support
- Qualcomm sdm845 and sda845 SoC IDs for socinfo"

The conversion to properties changed one assignment and
missed three other assignments in the same file, fix it
up so the platform compiles.
The bug was reported by a few build bots but noone noticed.
I noticed it when making other changes to the PXA platforms.

Couple of fixes:
1. Fix for UART clock frequency on all Juno variants that exist since
the platform was added. This is mainly due to incorrect Juno SoC
TRM that was referred during initial development days
2. Drop "dma-ranges" property for now as they are triggering loads of
warning on boot
