From: Nuno Sa <nuno.sa@analog.com> stable inclusion from stable-v6.6.33 commit 69f245b86cef49e5d4a0e75434988d431bf3ed00 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.
