Yeah, it does:
# cat /sys/kernel/debug/devices_deferred 32f10100.usb platform: supplier 32f10000.blk-ctrl not ready 32f10108.usb platform: supplier 32f10000.blk-ctrl not ready 32ec0000.blk-ctrl imx8m-blk-ctrl: failed to get noc entries 381f0040.usb-phy platform: supplier 32f10000.blk-ctrl not ready 382f0040.usb-phy platform: supplier 32f10000.blk-ctrl not ready imx-pgc-domain.11 imx-pgc-domain.12 imx-pgc-domain.13 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

I will try that.
Thanks Greg
