It would be nice if we could get rid of !DM_USB in ehci-mx6 as well. I may have
missed a few, but I think the following are all defconfigs with
'CONFIG_USB_EHCI_MX[67]=y' and 'CONFIG_SPL_DM_USB is not set':
imx6dl_mamoj_defconfig
imx8mp_data_modul_edm_sbc_defconfig
imx8mn_ddr4_evk_defconfig
imx8mp_dhcom_drc02_defconfig
imx8mp_dhcom_pdk2_defconfig
imx8mp_dhcom_pdk3_defconfig
imx8mp_dhcom_picoitx_defconfig
imxrt1050-evk_defconfig
imxrt1050-evk_fspi_defconfig
kontron-osm-s-mx8mp_defconfig
kp_imx6q_tpc_defconfig
I can propose a patch to drop the !DM_USB code, but out of these the
imx8mn_ddr4_evk is the only one I have here for testing.
Best,
Nora
