emul: spi: Add support for SPI emulators Add an emulation controller which routes SPI traffic to an attached emulator. Only one emulator is supported per bus at present, since chip-selction functionality is not present. This allows drivers for SPI peripherals to be tested on systems that don't have that peripheral attached, with the emulator handling the SPI traffic. Signed-off-by: Simon Glass <sjg@chromium.org>

drivers: spi: Update drivers to use devicetree Kconfig symbol Update spi drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

Enable the SPI emulator driver. This is a fake driver in that it
does not talk to real hardware. Instead it talks to emulation
drivers that pretend to be devices on the emulated SPI bus. It is
used for testing drivers for SPI devices.
