Thank you very much Alex,
Tried, tested and verified. Got it working with stable/master
(v5.10-rc5).
Regards,
Manuel

Hi there,
Mainline stable kernel 5.9.10 hangs indefinitely on a
STM32MP157A-DK1 Discovery Kit board.
Built plain vanilla 5.9.10 stable kernel for multi_v7_defconfig (set
compression to XZ) using arm-linux-gnueabi-gcc (Ubuntu
10.2.0-8ubuntu1) 10.2.0.
Downloaded it to the board memory via tftp running U-Boot v2020.07.
After boot, kernel initiates and prints several messages until it
hangs on:
[ 2.692879] stpmic1 1-0033: PMIC Chip Version: 0x10
[ 2.704158] vddcore: supplied by regulator-dummy
[ 2.710304] vdd_ddr: supplied by regulator-dummy
[ 2.716414] vdd: supplied by regulator-dummy
[ 2.722355] v3v3: supplied by regulator-dummy
[ 2.728033] v1v8_audio: supplied by v3v3
[ 2.734287] v3v3_hdmi: supplied by regulator-dummy
[ 2.741035] vtt_ddr: supplied by vdd_ddr
[ 2.743833] vdd_usb: supplied by regulator-dummy
[ 2.751332] vdda: supplied by regulator-dummy
[ 2.757371] v1v2_hdmi: supplied by v3v3
No other information or indication is given, even though I added
kernel debugging features such as the ones in "Kernel hacking
->Debug Oops, Lockups and Hangs".
Any help would be appreciated. Let me know if I can provide any
further information.
It has been introduced by commit aea6cb99703e ("regulator: resolve
supply after creating regulator") and should fixed by this one:
cf1ad559a20d ("regulator: defer probe when trying to get voltage from
unresolved supply").
Should be taken in stable tree.
regards
alex
