If reset-gpio is defined by device-tree use that if CONFIG_PCIE_IMX_PERST_GPIO is not defined. Note that after this the following boards which define CONFIG_PCIE_IMX_PERST_GPIO in their board header file as well as their device-tree should be able to remove CONFIG_PCIE_IMX_PERST_GPIO without consequence: - mx6sabresd - mx6sxsabresd - novena - tbs2910 - vining_2000 Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_PERST_GPIO and does not have reset-gpios defined it it's pcie node in the dt thus removing CONFIG_PCIE_IMX_PERST_GPIO globally can't be done until that board adds reset-gpios.
