That's LPCG_DI_LVDS_LPCG_0 for imx8qxp, no? So clock-indices and
clock-output-names should be split similar to patch.

That's LPCG_DI_MIPI_LPCG_12, no? imx8qm RM Rev 0 just lists one clock.
Also it's different on imx8qxp.

Just 0 instead of IMX_LPCG_CLK_0.

Order nodes by base address please.

I don't think that's correct. IMX_LPCG_CLK_4 evaluates to 16.
'mipi0_pwm_lpcg' only has 2 clocks, so you should use just '1' and '0'.

Just use 0 instead of IMX_LPCG_CLK_0.

This is only for imx8qm, no?
It maybe makes sense to rename this file to imx8qm-ss-mipi1.dtsi
