I've checked the vendor DT before they moved to the mainline driver, and th= ey never used this binding (actually they never made bindings).=20 Here's what the DT was: vpu: vpu@38300000 { compatible =3D "nxp,imx8mq-hantro"; reg =3D <0x38300000 0x200000>; reg-names =3D "regs_hantro"; interrupts =3D , ; interrupt-names =3D "irq_hantro_g1", "irq_hantro_g2"; clocks =3D <&clk IMX8MQ_CLK_VPU_G1_ROOT>, <&clk IMX8MQ_CLK_VPU_G2_ROOT>,= <&clk IMX8MQ_CLK_VPU_DEC_ROOT>; clock-names =3D "clk_hantro_g1", "clk_hantro_g2", "clk_hantro_bus"; assigned-clocks =3D <&clk IMX8MQ_CLK_VPU_G1>, <&clk IMX8MQ_CLK_VPU_G2>, = <&clk IMX8MQ_CLK_VPU_BUS>; assigned-clock-parents =3D <&clk IMX8MQ_VPU_PLL_OUT>, <&clk IMX8MQ_VPU_P= LL_OUT>, <&clk IMX8MQ_SYS1_PLL_800M>; assigned-clock-rates =3D <600000000>, <600000000>, <800000000>; power-domains =3D <&pgc_vpu>; status =3D "disabled"; }; I've not aware of any other OS or booloader that offers media capabilities = using Linux mainline DT. The now deprecated nxp,imx8mq-vpu compatible had a short= live in the Linux tree if my memory is correct.
