We missed out the clock operation handling patch (Commit 16ada730a759) and did not handle the clk_ops for Keem Bay SOC devices. These 2 patches (Commit 16ada730a759) and (Commit 36c6aadaae86) are merged at around the same time. We catch the issue later when trying to boot into v5.10-rc1 with Keem Bay EVM.

So, you are saying that it has never worked for Keem Bay? But $subject patch makes it work? Can you please re-spin and update the commit message to better reflect what goes on, then I can apply.
