Radxa dalang carrier board has 2x USB 2.0 and 1x USB 3.0
ports.
This patch adds support to enable all these USB ports for
N10 and N8 combinations SBCs.
Note that the USB 3.0 port on RockPI N8 combination works
as USB 2.0 OTG since it is driven from RK3288.

rk3288 and rk3288w have a usb host0 ohci controller.
Although rk3288 ohci doesn't actually work on hardware, but
rk3288w ohci can work well.
So add usb host0 ohci node in rk3288 dtsi and boards
can then enable it if supported.

The following commit:
14533a16c46d ("thermal/cpu-cooling, sched/core: Move the arch_set_thermal_pressure() API to generic scheduler code")
moved the definition of arch_set_thermal_pressure() to sched/core.c, but
kept its declaration in linux/arch_topology.h. When building e.g. an x86
kernel with CONFIG_SCHED_THERMAL_PRESSURE=y, cpufreq_cooling.c ends up
getting the declaration of arch_set_thermal_pressure() from
include/linux/arch_topology.h, which is somewhat awkward.
On top of this, sched/core.c unconditionally defines
o The thermal_pressure percpu variable
o arch_set_thermal_pressure()
while arch_scale_thermal_pressure() does nothing unless redefined by the
architecture.
arch_*() functions are meant to be defined by architectures, so revert the
aforementioned commit and re-implement it in a way that keeps
arch_set_thermal_pressure() architecture-definable, and doesn't define the
thermal pressure percpu variable for kernels that don't need
it (CONFIG_SCHED_THERMAL_PRESSURE=n).

Since clang does not push pc and sp in function prologues, the current
implementation of unwind_frame does not work. By using the previous
frame's lr/fp instead of saved pc/sp we get valid unwinds on clang-built
kernels.
The bounds check on next frame pointer must be changed as well since
there are 8 less bytes between frames.
This fixes /proc/<pid>/stack.

The integrated assembler of Clang 10 and earlier do not allow to access
the VFP registers through the coprocessor load/store instructions:
arch/arm/vfp/vfpmodule.c:342:2: error: invalid operand for instruction
fmxr(FPEXC, fpexc & ~(FPEXC_EX|FPEXC_DEX|FPEXC_FP2V|FPEXC_VV|FPEXC_TRAP_MASK));
^
arch/arm/vfp/vfpinstr.h:79:6: note: expanded from macro 'fmxr'
asm("mcr p10, 7, %0, " vfpreg(_vfp_) ", cr0, 0 @ fmxr " #_vfp_ ", %0"
^
<inline asm>:1:6: note: instantiated into assembly here
mcr p10, 7, r0, cr8, cr0, 0 @ fmxr FPEXC, r0
^
This has been addressed with Clang 11 [0]. However, to support earlier
versions of Clang and for better readability use of VFP assembler
mnemonics still is preferred.
Ideally we would replace this code with the unified assembler language
mnemonics vmrs/vmsr on call sites along with .fpu assembler directives.
The GNU assembler supports the .fpu directive at least since 2.17 (when
documentation has been added). Since Linux requires binutils 2.21 it is
safe to use .fpu directive. However, binutils does not allow to use
FPINST or FPINST2 as an argument to vmrs/vmsr instructions up to
binutils 2.24 (see binutils commit 16d02dc907c5):
arch/arm/vfp/vfphw.S: Assembler messages:
arch/arm/vfp/vfphw.S:162: Error: operand 0 must be FPSID or FPSCR pr FPEXC -- `vmsr FPINST,r6'
arch/arm/vfp/vfphw.S:165: Error: operand 0 must be FPSID or FPSCR pr FPEXC -- `vmsr FPINST2,r8'
arch/arm/vfp/vfphw.S:235: Error: operand 1 must be a VFP extension System Register -- `vmrs r3,FPINST'
arch/arm/vfp/vfphw.S:238: Error: operand 1 must be a VFP extension System Register -- `vmrs r12,FPINST2'
Use as-instr in Kconfig to check if FPINST/FPINST2 can be used. If they
can be used make use of .fpu directives and UAL VFP mnemonics for
register access.
This allows to build vfpmodule.c with Clang and its integrated assembler.

<instantiation>:4:6: error: invalid operand for instruction

This has been addressed with Clang 11 [0]. However, to support earlier

mnemonics still is preferred.
Replace the coprocessor load/store instructions with explicit assembler
mnemonics to accessing the floating point coprocessor registers. Use
assembler directives to select the appropriate FPU version.
This allows to build these macros with GNU assembler as well as with
Clang's built-in assembler.

Explicit FPU selection has been introduced in commit 1a6be26d5b1a
("[ARM] Enable VFP to be built when non-VFP capable CPUs are selected")
to make use of assembler mnemonics for VFP instructions.
However, clang currently does not support passing assembler flags
like this and errors out with:
clang-10: error: the clang compiler does not support '-Wa,-mfpu=softvfp+vfp'
Make use of the .fpu assembler directives to select the floating point
hardware selectively. Also use the new unified assembler language
mnemonics. This allows to build these procedures with Clang.

create_mapping_late()
Commit
84e6ffb2c49c7901 ("arm: add support for folded p4d page tables")
updated create_mapping_late() to take folded P4Ds into account when
creating mappings, but inverted the p4d_alloc() failure test, resulting
in no mapping to be created at all.
When the EFI rtc driver subsequently tries to invoke the EFI GetTime()
service, the memory regions covering the EFI data structures are missing
from the page tables, resulting in a crash like

Unprivileged memory accesses generated by the so-called "translated"
instructions (e.g. LDRT) in kernel mode can cause user watchpoints to fire
unexpectedly. In such cases, the hw_breakpoint logic will invoke the user
overflow handler which will typically raise a SIGTRAP back to the current
task. This is futile when returning back to the kernel because (a) the
signal won't have been delivered and (b) userspace can't handle the thing
anyway.
Avoid invoking the user overflow handler for watchpoints triggered by
kernel uaccess routines, and instead single-step over the faulting
instruction as we would if no overflow handler had been installed.

The OMAP1 OHCI driver is using the legacy GPIO API to grab some
random GPIO lines. One is from the TPS65010 chip and used for
power, another one is for overcurrent and while the driver picks
this line it doesn't watch it at all.
Convert the driver and the OMAP1 OSK board file to pass these
two GPIOs as machine described GPIO descriptors.
I noticed the overcurrent GPIO line is not really used in the
code so dropped in a little comment for other developers.

The Bananapi M2+ uses a GPIO line to change the effective resistance of
the CPU supply regulator's feedback resistor network. The voltages
described in the device tree were given directly by the vendor. This
turns out to be slightly off compared to the real values.
The updated voltages are based on calculations of the feedback resistor
network, and verified down to three decimal places with a multi-meter.

The device tree currently only assigns the a supply for the first CPU
core, when in reality the regulator supply is shared by all four cores.
This might cause an issue if the implementation does not realize the
sharing of the supply.
Assign the same regulator supply to the remaining CPU cores to address
this.

Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the
KSZ9031 PHY"), networking is broken on sama5d3 xplained.
The device tree has phy-mode = "rgmii" and this worked before, because
KSZ9031 PHY started with default RGMII internal delays configuration (TX
off, RX on 1.2 ns) and MAC provided TX delay. After above commit, the
KSZ9031 PHY starts handling phy mode properly and disables RX delay, as
result networking is become broken.
Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous
behavior.

Commit 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the
values correct for Exynos5422 Odroids") changed the parameters of the
OPPs for the FSYS bus. Besides the frequency adjustments, it also removed
the 'shared-opp' property from the OPP table used for FSYS_APB and FSYS
busses.
This revealed that in fact the FSYS bus frequency scaling never worked.
When one OPP table is marked as 'opp-shared', only the first bus which
selects the OPP sets the rate of its clock. Then OPP core assumes that
the other busses have been changed to that OPP and no change to their
clock rates are needed. Thus when FSYS_APB bus, which was registered
first, set the rate for its clock, the OPP core did not change the FSYS
bus clock later.
The mentioned commit removed that behavior, what introduced a regression
on some Odroid XU3 boards. Frequency scaling of the FSYS bus causes
instability of the USB host operation, what can be observed as network
hangs. To restore old behavior, simply disable frequency scaling for the
FSYS bus.

GPIOP7 is used in the Rainier design to manage the state of a
microcontroller elsewhere in the system but its ball, Y23, is the
driver of the heartbeat LED on the ast2600-evb and the SoC defaults Y23
at power-on to the pulse-train behaviour used to drive the LED. This
causes much confusion for the micro in the Rainier system, so hog the
line as early as possible.
