Some devices (eg. Dell XPS 9530, 2023) due to a firmware bug have a misconfigured clock divider, which should've been 1:1. This introduces quirk which conditionally re-configures the clock divider to 1:1.

commit 1d8c51ed2ddcc4161e6496cf14fcd83921c50ec8 upstream.

Some devices (eg. Dell XPS 9530, 2023) due to a firmware bug have a
misconfigured clock divider, which should've been 1:1. This introduces
quirk which conditionally re-configures the clock divider to 1:1.
