After commit71de0a054d("arm64: tegra: Drop serial clock-names and reset-names") was applied, the HSUART failed to probe and the following error is seen: serial-tegra 3100000.serial: Couldn't get the reset serial-tegra: probe of 3100000.serial failed with error -2 Commit71de0a054d("arm64: tegra: Drop serial clock-names and reset-names") is correct because the "reset-names" property is not needed for 8250 UARTs. However, the "reset-names" is required for the HSUART and should have been populated as part of commitff578db7b6("arm64: tegra: Enable UART instance on 40-pin header") that enabled the HSUART for Jetson AGX Orin. Fix this by populating the "reset-names" property for the HSUART on Jetson AGX Orin.

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 Restructured Text 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.
