[v3] Basic clock and reset support for StarFive JH7110 RISC-V SoC

[PATCH v3 03/11] reset: Create subdirectory for StarFive drivers

Posted by Hal Feng 2 years, 9 months ago

From: Emil Renner Berthing <kernel@esmil.dk>

This moves the StarFive JH7100 reset driver to a new subdirectory in
preparation for adding more StarFive reset drivers.

You could in theory drop the default that I added & replace it with a y,
since the subdir is gated by the symbol. I don't really care though tbh.
The movement seems fine to me..

If you don't mind, I would like to keep it because the starfive clk subdir
did the same before.
