[PATCH 1/5] clk: Add support for clock nexus dt bindings

[Chancel Liu]

Hi all,

Please ignore this patch.

I noticed that the same change was already posted earlier by Miquel Raynal
as part of his series ([PATCH 10/16] clk: Add support for clock nexus dt bindings):
 https://lkml.org/lkml/2026/3/27/1983

To avoid duplication, noise, and wasted review time, I will drop my patch.

Regarding the questions raised by the sashiko review (e.g. assigned-clocks /
assigned-clock-parents behavior with nexus nodes), this aligns with the
ongoing discussion in Miquel's thread so I suggest we continue the discussion there.

Sorry for the noise.

Regards, 
Chancel Liu
