qcn9274 hw2.0 in banana pi r64 - LTSSM read fail

[Janusz Dziedzic]

Hello,

I have this card in bpi-r64 board. Need to hash: ath12k_pci_enable_ltssm()
While board hang here (next board restart):

val = ath12k_pci_read32(ab, PCIE_PCIE_PARF_LTSSM);

Is it a 12k bug/MTK pci controller bug?
When hash it works correctly.
