Its real name is IMX8MP_CLK_AUDIOMIX_PDM_SEL. I'll submit a patch to remove this from imx8mp-clock.h and and a V3 of this series to update the clock reference in this node. > + <&clk IMX8MP_AUDIO_PLL1_OUT>, > + <&clk IMX8MP_AUDIO_PLL2_OUT>, > + <&clk IMX8MP_CLK_EXT3>; > + clock-names = "ipg_clk", "ipg_clk_app", > + "pll8k", "pll11k", "clkext3"; > + dmas = <&sdma2 24 25 0x80000000>; > + dma-names = "rx"; > + status = "disabled"; > + }; > + > }; > > sdma3: dma-controller@30e00000 { > -- > 2.39.2 >

The i.MX8MP has a micfil controller which is used for interfacing with a pulse density microphone. Add the node and mark it as disabled by default. Signed-off-by: Adam Ford <aford173@gmail.com> --- V2: No Change
