Now, even back then Serial Peripheral Interface doesn't technically imply that any I/O memory is required for operation / communication between the master/host and the slaves/clients. That said, most of the host controller do need it. But there are some exceptions: - SPI_GPIO (gpio bit-banged) - SPI_BUTTERFLY (Parallel port adapter for AVR Butterfly (DEVELOPMENT)) - SPI_SC18IS602 (NXP SC18IS602/602B/603 I2C to SPI bridge) - SPI_XCOMM (Analog Devices AD-FMCOMMS1-EBZ SPI-I2C-bridge driver) - SPI_LJCA (Intel La Jolla Cove Adapter SPI support - USB) - SPI_CH341 (CH341 USB2SPI adapter) - (SPI_RPCIF) (Renesas RPC-IF SPI driver) - RPC This patch >tries< to remove the single HAS_IOMEM dependency down to the individual driver. Some - presumably newer - drivers already had the "depends on HAS_IOMEM". For now, I settled with just adding it. With no regards even if PCI, DMA, REGMAP_MMIO or some ARCH has been set, which would definitely imply that we have IOMEM. But if there's an interest, I will totally look into which "depends on HAS_IOMEM" can be integrated into other existing "depends on" or if they can simply be skipped altogether since PCI/ARCH is set that does imply HAS_IOMEM. Ideally, nothing should break. Though, I would bet that the robots will probably tell me otherwise :) .
