I thought you may have other boot blocking issues so this wouldn't be a critical fix.

So yes please. Unless you enable USB support, because configuring the first USB controller in host currently crashes the device - I've not yet found the cause for this though. Regards, Bjorn

As of v4.20-rc1 probing the GCC driver on a SDM845 device with the standard security implementation causes an access violation and an immediate system restart. Use the protected-clocks property to mark the offending clocks protected for the MTP, in order to allow it to boot.
