Subject: [PATCH v4 0/2] gs101 oriole: UART clock fixes

Hi,

This series fixes a long-standing issue in the gs101 clocking / uart
handling.

We can now disable clocks that had previously been marked critical, and
still get a working earlycon.

There is a preparatory patch, and then a patch to drop an incorrect clock
counting work-around. That 2nd patch is essentially the last remaining patch
[1] with all review comments addressed, from the series [2] that was sent
earlier this year, see lore links below.

Patch 2 can not come before or without patch 1.
