Unfortunately, it makes it impossible to use the driver across PCIe - which is a specifically desired configuration. Could you add CONFIG_PCI to the || chain? Cheers,

Is PCIe the only other transport over which the register can be accessed? Or can this also be done over e.g. SPI, like on Ocelot[1]?

Hence would you consider depends on ARCH_SPARX5 || SOC_VCOREIII || PCI || SPI || COMPILE_TEST acceptable? Or would that be futile, as must systems have PCI and/or SPI enabled anyway?

the Microsemi/Microchip Serial GPIO device is present only Microsemi VCore III and Microchip Sparx5 SoCs.
