Any thoughts on why this breaks USB?
Maybe you are missing CONFIG_INTERCONNECT_IMX8MP?
And if that's the case, did you check /sys/kernel/debug/devices_deferred
to see if there was any indication that this is the reason?
Yeah, it does:
# cat /sys/kernel/debug/devices_deferred

32f10108.usb platform: supplier 32f10000.blk-ctrl not ready

38330000.blk-ctrl platform: supplier imx-pgc-domain.11 not ready
32f10000.blk-ctrl imx8mp-blk-ctrl: failed to get noc entries
As far as I can tell blk-ctrl should be good:
#
# i.MX SoC drivers
#
CONFIG_IMX_GPCV2_PM_DOMAINS=y
CONFIG_SOC_IMX8M=y
# CONFIG_SOC_IMX9 is not set
CONFIG_IMX8M_BLK_CTRL=y
# end of i.MX SoC drivers
If you didn't find any hint there, you might want to place a
dev_err_probe with a suitable message at the place where -EPROBE_DEFER
was returned.
I will try that.
Can you check that CONFIG_ARM_IMX_BUS_DEVFREQ is enabled? This is the
noc/interconnect driver. This could also the problem for you vpu issue.
I do not have that enabled. Enabling that fixes the USB probing.
So that is good, thanks.
It doesn't fix the other problem I mentioned with the vpu pgc nodes though.
I do get some extra messages now with this enabled and the 6.1 kernel:
imx-pgc imx-pgc-domain.8: failed to command PGC
imx-pgc imx-pgc-domain.8: failed to command PGC
imx8m-blk-ctrl 38330000.blk-ctrl: deferred probe timeout, ignoring dependency
