6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nuno Sa <nuno.sa@xxxxxxxxxx>
[ Upstream commit 19fb11d7220b8abc016aa254dc7e6d9f2d49b178 ]
Add a required clock property as we can't access the device registers if
the AXI bus clock is not properly enabled.
Note this clock is a very fundamental one that is typically enabled
pretty early during boot. Independently of that, we should really rely on
it to be enabled.
