Add private uclass data for "stm32-usbphyc-clk" as it is not done
by the driver model.
This clk struct is needed by CCF to save the unique id used to identify
each clock.

As part of bringing the master branch back in to next, we need to allow

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

This old patch was marked as deferred. Bring it back to life, to continue
towards the removal of common.h
Move this out of the common header and include it only where needed.

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so fix some
debug strings with fdt_addr_t to be able to handle both sizes.

Use regulator_set_enable_if_allowed() api instead of regulator_set_enable()
while disabling vbus supply. This way the driver doesn't see an error
when it disable an always-on regulator for VBUS.
This patch is needed for STM32MP157C-DK2 board when the regulator
v3v3: buck4 used as the phy vbus supply in kernel device tree
is always on with the next hack for low power use-case:
&usbphyc_port0 {
...
/*
* Hack to keep hub active until all connected devices are suspended
* otherwise the hub will be powered off as soon as the v3v3 is disabled
* and it can disturb connected devices.
*/
connector {
compatible = "usb-a-connector";
vbus-supply = <&v3v3>;
};
};
Without this patch and the previous update in DT the command
"usb stop" failed and the next command "usb start" cause a crash.

ck_usbo_48m is generated by usbphyc PLL and used by OTG controller
for Full-Speed use cases with dedicated Full-Speed transceiver.

Add the counter of the PLL user n_pll_cons managed by the 2 functions
stm32_usbphyc_pll_enable / stm32_usbphyc_pll_disable.
This counter allow to remove the function stm32_usbphyc_is_init
and it is a preliminary step for ck_usbo_48m introduction.

and no more in the usb phyc node (in first proposed binding).
This regulator for USB VBUS may be needed for host mode.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Use regulator_set_enable_if_allowed() api instead of regulator_set_enable()
while disabling vdd supply. This way the driver doesn't see an error
when disabling an always-on regulator.
This patch is needed since the commit f93fab312615 ("Revert 'power:
regulator: Return success on attempt to disable an always-on regulator'")
and use the API introduced by commit cc4a224af226 ("power: regulator:

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

Controller (usbphyc) that provides dual port High-Speed
phy for OTG (single port) and EHCI/OHCI host controller
(two ports).
One port of the phy is shared between the two USB controllers
through a UTMI+ switch.
