When the clock speed is above about 4GHz, e.g. on modern PC hardware,
the timer overflows, resulting in a much lower frequency than expected.
Deal with this by capping the clock speed.
It would be possible to move to a 64-bit value for the clock, but that
is a pain to deal with. A better approach might be to express the clock
in MHz but that is left for later consideration.

U-Boot device tree is padded just after U-Boot proper.
After the whole stuff loaded to DRAM space, the device tree
area is conflict with BSS region before U-Boot relocation.
So any write to BSS area before reloc_fdt will corrupt the

Currently the enablement of OF_UPSTREAM results on the build system
searching for DTs only in dts/upstream/ . There are platforms which
use U-Boot specific DTBOs applied on top of U-Boot control DT during
SPL stage, and source DTs for these are located in arch/$(ARCH)/dtb.
Add dedicated 'dtbos' target which builds only .dtbos and not .dtbs and
in case CONFIG_OF_UPSTREAM_INCLUDE_LOCAL_FALLBACK_DTBOS is enabled, build
this target for arch/$(ARCH)/dtb to generate local U-Boot specific DTBOs.
Adjust top level Makefile so binman would search for .dtb and .dtbo in
both OF_UPSTREAM specific paths and arch/$(ARCH)/dtb for the .dtbo case
in case CONFIG_OF_UPSTREAM_INCLUDE_LOCAL_FALLBACK_DTBOS is enabled.

AM62x devices now support CPU throttling based on thermal alerts
with a Linux commit 10e7bfd8114c ("arm64: dts: ti: k3-am62: Enable
CPU freq throttling on thermal alert"). However, this functionality
does not work correctly across all variants of the AM62x SoCs
which have different numbers of Cortex-A CPU cores: AM62x1 (1 core),
AM62x2 (2 cores), and AM62x4 (4 cores). On single-core and dual-core
AM62x devices, the following error is observed in the Linux kernel:
OF: /thermal-zones/main0-thermal/cooling-maps/map0: could not find
phandle 94
OF: /thermal-zones/main1-thermal/cooling-maps/map0: could not find
phandle 94
This commit adds a fixup to dynamically adjust the cooling-device
nodes in the thermal zones based on the actual number of CPU cores
available. This resolves the issue of CPU throttling not working
correctly on single-core and dual-core AM62x devices, while
maintaining the functionality for AM62x quad-core devices.
A similar approach is implemented for example on i.MX8MM SoC.

Add USB-C controller (fusb302), which will be used by U-Boot to
initialize USB-PD. This is needed, because USB-PD communication
must happen within 5 seconds after the USB-C connector got plugged.
On my Rock 5B it often takes 5 seconds to jump to the Linux binary,
so it must happen before Linux is initialized.
This adds the DT node to the U-Boot specific file, since the Linux
kernel DT currently does not describe it to avoid a system reset.
The plan is to add it to the Linux DT with status = 'fail' and then
let U-Boot mark it as status = 'okay' if it properly dealt with
early USB-PD initialization. Until the Kernel DT has the node, let's
add it in U-Boot to get things going.

Since older U-Boot releases do not negotiate USB PD, the kernel
DT may not enable the USB-C controller by default to avoid a
regression. The plan is to upstream it with 'status = "fail";'
instead. U-Boot should then mark it as 'status = "okay";' if
it negotiated USB PD. Currently existing upstream kernel DTs do
not yet have the USB-C controller at all, so we ignore any
failures.

Now that the TCPM framework exists we can introduce fusb302
driver using it. This chip is a very common USB-C controller
chip with PD support, which can be found in the Radxa Rock 5B
among many other boards. Apart from Power Delivery, it also
handles detection of the cable orientation. That can be used
to control a mux for connecting the right USB3 lane pair to
the USB3 controller.
The driver is originally from the Linux kernel, but has been
adapted to the requirements of U-Boot and its TCPM framework.

This adds TCPM framework in preparation for fusb302 support, which can
handle USB power delivery messages. This is needed to solve issues with
devices, that are running from a USB-C port supporting USB-PD, but not
having a battery.
Such a device currently boots to the kernel without interacting with
the power-supply at all. If there are no USB-PD message replies within
5 seconds, the power-supply assumes the peripheral is not capable of
USB-PD. It usually takes more than 5 seconds for the system to reach
the kernel and probe the I2C based fusb302 chip driver. Thus the
system always runs into this state. The power-supply's solution to
fix this error state is a hard reset, which involves removing the
power from VBUS. Boards without a battery (or huge capacitors) will
reset at this point resulting in a boot loop.
This imports the TCPM framework from the kernel. The porting has
originally been done by Rockchip using hardware timers and the Linux
kernel's TCPM code from some years ago.
I had a look at upgrading to the latest TCPM kernel code, but that
beast became a lot more complex due to adding more USB-C features.
I believe these features are not needed in U-Boot and with multiple
kthreads and hrtimers being involved it is non-trivial to port them.
Instead I worked on stripping down features from the Rockchip port
to an even more basic level. Also the TCPM code has been reworked
to avoid complete use of any timers (Rockchip used SoC specific
hardware timers + IRQ to implement delayed work mechanism). Instead
the delayed state changes are handled directly from the poll loop.
Note, that (in contrast to the original Rockchip port) the state
machine has the same hard reset quirk, that the kernel has - i.e.
it avoids disabling the CC pin resistors for devices that are not
self-powered. Without that quirk, the Radxa Rock 5B will not just
end up doing a machine reset when a hard reset is triggered, but will
not even recover, because the CPU will loose power and the FUSB302
will keep this state because of leak voltage arriving through the RX
serial pin (assuming a serial adapter is connected).
This also includes a 'tcpm' command, which can be used to get
information about the current state and the negotiated voltage
and current.
