So do you need any help with this? Won't you mind if we start up-streaming at least xhci-imx8.c, which is used in both our SoMs Apalis iMX8 and Colibri iMX8QXP. Based on what I've seen in [1], the initial conversion to DM_USB is already done. Is there anything else that is expected to be changed in xhci-imx8.c (by asking this I just want to avoid duplicating the effort)? Frankly, this is currently a kind of showstopper for us, as it adds some complications for the next release of our BSP (we would like to enable usb host/gadget support or iMX8-based SoMS, including all dependent features like fastboot/usb storage/ums etc.), where we made a decision to move towards the usage of the mainline U-boot (with the minimal divergence and minimal amount of legacy downstream patches on top of it). > > > Regards, > Peng. > > > > > Thanks and looking forward to your reply! > > > > [1] > > https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fgit.free > > scale.com%2Fgit%2Fcgit.cgi%2Fimx%2Fuboot-imx.git&data=02%7C01% > > 7Cpeng.fan%40nxp.com%7Ccb5c23c8a4764b489d6308d6fa32e9cf%7C686ea > > 1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C636971493909583933& > > sdata=HcUVX2n%2BdzUNtkuF%2BC4IoFRuMtZpZpJvBpwoqk20Lrk%3D& > > reserved=0 > > [2] > > https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsource > > .codeaurora.org%2Fexternal%2Fimx%2Fuboot-imx%2Ftree%2Fdrivers%2Fusb > > %2Fhost%2Fxhci-imx8m.c%3Fh%3Dimx_v2017.03_4.9.88_imx8qxp_beta2&a > > mp;data=02%7C01%7Cpeng.fan%40nxp.com%7Ccb5c23c8a4764b489d6308d > > 6fa32e9cf%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C6369714 > > 93909583933&sdata=Dvp5XlU8Zcj9wJJ2cvD8taPCbitVKVjpGyyFHonTF% > > 2Bs%3D&reserved=0 > > [3] > > https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsource > > .codeaurora.org%2Fexternal%2Fimx%2Fuboot-imx%2Ftree%2Fdrivers%2Fusb > > %2Fhost%2Fxhci-imx8.c%3Fh%3Dimx_v2017.03_4.9.88_imx8qxp_beta2&am > > p;data=02%7C01%7Cpeng.fan%40nxp.com%7Ccb5c23c8a4764b489d6308d6f > > a32e9cf%7C686ea1d3bc2b4c6fa92cd99c5c301635%7C0%7C0%7C63697149 > > 3909583933&sdata=v5%2FiQYxvpLLPjj5QcHQ8dC8RfoFkNVfMbKQ79rW > > wV4c%3D&reserved=0 > > > > -- > > Best regards - Freundliche Grüsse - Meilleures salutations > > > > Igor Opaniuk > > > > mailto: igor.opan...@gmail.com > > skype: igor.opanyuk > > +380 (93) 836 40 67 > > https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fua.linke > > din.com%2Fin%2Fiopaniuk&data=02%7C01%7Cpeng.fan%40nxp.com%7 > > Ccb5c23c8a4764b489d6308d6fa32e9cf%7C686ea1d3bc2b4c6fa92cd99c5c30 > > 1635%7C0%7C0%7C636971493909583933&sdata=gwm7kV8EAYWThz3 > > %2FtbvYc9ahqla2OkcR83MRmY5DK%2FI%3D&reserved=0 [1] https://source.codeaurora.org/external/imx/uboot-imx/tree/drivers/usb/host/xhci-imx8.c?h=imx_v2018.03_4.14.98_2.0.0_ga Thanks! -- Best regards - Freundliche Grüsse - Meilleures salutations Igor Opaniuk mailto: igor.opan...@gmail.com skype: igor.opanyuk +380 (93) 836 40 67 http://ua.linkedin.com/in/iopaniuk _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
