Hello,
> Airoha EN7581 has a hw bug asserting/releasing PCIE_PE_RSTB signal
> causing occasional PCIe link down issues. In order to overcome the
> problem, PCIE_RSTB signals are not asserted/released during device probe or
> suspend/resume phase and the PCIe block is reset using REG_PCI_CONTROL
> (0x88) and REG_RESET_CONTROL (0x834) registers available in the clock
> module running clk_bulk_prepare_enable in mtk_pcie_en7581_power_up().
>
> Introduce flags field in the mtk_gen3_pcie_pdata struct in order to
> specify per-SoC capabilities.
Applied to controller/mediatek, thank you!
