[PATCH 12/13] clk: imx: imx8mp: allow LVDS clocks to set parent rate
From: Benjamin Bara
Date: Sun Sep 17 2023 - 18:44:20 EST
From: Benjamin Bara <benjamin.bara@xxxxxxxxxxx>
As composit-8m are now ready to dynamically propagate the
required clock rate and pll14xx is able to keep its children in the
configured state, allow media_ldb and media_disp2_pix to set the rate of
their parent (which is usually video_pll for both).
