Introduce dedicated field 'power_on_delay_us' in onboard platform data and update its delay for USB5744 configuration. Hub itself requires some delay after reset to get to state where configuration data is going to be accepted. Without delay upcoming support for configuration via SMBUS is reporting a failure on the first SMBus write. i2c 2-002d: error -ENXIO: BYPASS_UDC_SUSPEND bit configuration failed Similar delay is likely also required for default configuration but because there is enough time (code execution) between reset and usage of the hub any issue is not visible but it doesn't mean delay shouldn't be reflected.

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.
