Hi Marek,
Hi,
I noticed that USB gadget does not work in U-Boot mainline on a warp7 board:
=> ums 0 mmc 0
UMS: LUN 0, dev mmc 0, hwpart 0, sector 0x0, count 0xe18000
g_dnl_register: failed!, error: -2
g_dnl_register failed
2021.04 works fine. I bisected and it pointed to:
4dcfa3bcbcbc5e0f7da145fff41e120392433062 is the first bad commit

usb: ehci-mx6: Parse USB PHY and MISC offsets from DT
In case DM and OF controler is enabled, but PHY support is disabled,
parse USB PHY and MISC component addresses from DT manually. Those
component addresses will be used in subsequent patches to access the
ANATOP, PHY and MISC registers matching the controller and thus get
rid of the ad-hoc controller sequence number mapping.
[...]
fdtdec_get_alias_seq() fails inside mx6_parse_dt_addrs().
Any suggestions?
There is no fdtdec_get_alias_seq() in the above commit , and in fact,
there shouldn't be, since all the sub-device addresses and offsets
should be parsed out of DT now. So the only suggestion I can offer is,
look into your DT and see whether the parsing can find all the props there.
