Re: [PATCH] dt-bindings: serial: 8250: spacemit: fix clock property for K3 SoC

[Yixun Lan <dlan@gentoo.org>]

Hi Greg, Jiri,

  Do you mind if I taking this patch via SpacemiT's SoC tree? and if
possible, it would be nice to have your Acks..
(or either way works for me, if you grab it and merged via tty tree)

I would just drop the Fixes tag, as I think at the time of Gudong
submitting the patch, the clock driver isn't ready, so he deliberatly
removed this clock contraint and provided with a fixed clock frequency
(the bindings match with DTS)
