Cover letter [PATCH 0/4] Make Armada 375 use the reference clock when possible
Dear Gregory CLEMENT,

This series adds support for the 25 MHz reference clock available on Armada 375 SoC to use on the timer and watchdog drivers. It is similar to the one present in Armada XP SoC.
I agree with Thomas P. comments: could you see if it was possible to reuse the same function and dt bindings that the ones used for Armada XP ?
I am not aware of any difference between Armada XP and Armada 375 for this IP.
Well, there's one difference: on Armada XP we don't need to support the "old" Device Tree, which didn't had the fixed 25 Mhz clock input described.
So either we decide that it was a mistake due to an early version of the 375 and we skip backward DT compatibility. Or we need in some way a different logic than Armada XP, because Armada XP doesn't have this backward compatibility requirement.
