I think it's very simple:
The DT node usually looks like so:
display@10120000 {
compatible = "arm,pl110", "arm,primecell";
(...)
clocks = <&oscclk4>, <&pclk>;
clock-names = "clcd", "apb_pclk";
Just add a custom attribute pointing to the
reference clock in this array:
clcd-reference-clock = <0>;
If this is set to <1> "apb_pclk" (i.e. HCLK) is
the reference, and that bit in TIM2 gets set.
Do you have a system that needs this?
