Hi,
I tried this branch, with only the sm8250-hdk.dts from my other series added (USB nodes removed as you don't have those in your branch), and the GPU starts up without problems.
Possible differences I can think of:
1) Different firmware version which behaves differently? These are the checksums for the firmware I have:
/lib/firmware# md5sum a650_* f6536ba45c2f9f64ec31438217b6a027 a650_gmu.bin 897be740bed67deaa1943e9c36293165 a650_sqe.fw 00f1b291a2b30c98f05c25506e3f4761 a650_zap.b00 bec0f79c7c6f5b32254facf3c7e046c7 a650_zap.b01 35273e4135147a269076144a3051b498 a650_zap.b02 ce0dd1af27306eb341a01bda642f1c64 a650_zap.elf 09834955a8865073f6ee483f69a98b33 a650_zap.mdt
2) GPU revision is not 650.2 (the downstream driver had workarounds for bugs in the first revisions, which I didn't include in the upstream driver)
3) Something in the kernel config is making a difference. Here is the kernel config I used to test this: https://gist.github.com/flto/c6b1bc48abda6fb580a2f21c51039c81
