Hi,
as you might have noticed, Bin Meng is currently greatly improving the U-Boot xHCI support. While doing this, he noticed that some additions are more complex and especially ugly to add, since some users of the xHCI support have not enabled CONFIG_DM_USB. This adds ugly #ifdef's, which we really would like to avoid. Because of this we checked, which boards exactly are using xHCI without DM_USB enabled. Here a complete list of all the boards:
ls1012ardb_qspi_SECURE_BOOT ls1021atwr_nor_SECURE_BOOT am43xx_hs_evm am57xx_hs_evm ls1021aqds_nand ls1021atwr_nor ls1021atwr_qspi cm_t43 ls1021atwr_nor_lpuart ls1021aqds_sdcard_qspi k2hk_hs_evm am43xx_evm ls1021aqds_qspi am57xx_evm_nodt k2g_hs_evm ls1021atwr_sdcard_qspi am43xx_evm_ethboot ls1021aqds_sdcard_ifc k2l_evm am43xx_evm_usbhost_boot am43xx_evm_qspiboot k2g_evm am57xx_evm ls1021atwr_sdcard_ifc cl-som-am57x k2hk_evm k2e_evm ls1021atwr_sdcard_ifc_SECURE_BOOT ls1021aqds_nor_SECURE_BOOT k2e_hs_evm
For TI platforms, there is some work needed to convert xhci-dwc3, xhci-omap and xhci-keystone to DM (under drivers/usb/host)
But the bigger concern of enabling DM_USB is with gadget framework, which is not DM compliant yet. There is a significant amount work[1][2] there before dwc3 gadget can be moved to DM and we can enable DM_USB.
