[PATCH v2 4/4] clk: imx: clk-audiomix: Corrent parent clock for earc_phy and audpll

From: Shengjiu Wang <hidden>
Date: 2024-05-09 02:03:40
Also in: imx, linux-clk, linux-devicetree, lkml
Subsystem: common clk framework, nxp i.mx clock drivers, the rest · Maintainers: Michael Turquette, Stephen Boyd, Abel Vesa, Linus Torvalds

According to Reference Manual of i.MX8MP
The parent clock of "earc_phy" is "sai_pll_out_div2",
The parent clock of "audpll" is "osc_24m".

Add CLK_GATE_PARENT() macro for usage of specifying parent clock.

Fixes: 6cd95f7b151c ("clk: imx: imx8mp: Add audiomix block control")
