The LXA device trees are the only STM32MP1 device tree that specify vusb_d/usb_a-supply and apparently not for good reason: - vusb_d-supply (vdd_usb) is the same as the phy-supply for usbphyc_port1 - vusb_a-supply (reg18) is the same as vdda1v8-supply for usbphyc_port1 and usbphyc_port1 is linked to the usbotg_hs node via the phys property. Specifying the regulators in the &usbotg_hs node is thus superfluous and has been even found to be harmful in one instance: Linux v6.10 was found to lock up every 50-125 or so reboots on the LXA TAC when the DWC2 driver probe enables the regulators in bulk, unless both properties were removed. This issue was so far not reproducible on v6.17 (> 500 reboots), but as these properties are unnecessary and different from other STM32MP1 boards, remove them anyway.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
