    spi/pxa2xx: embed the ssp_device to platform data · 851bacf5
    Mika Westerberg authored
    The spi-pxa2xx-pci glue driver had to implement pxa_ssp_request()/free() in
    order to support the spi-pxa2xx platform driver. Since the ACPI enabled
    platforms can use the same platform driver we would need to implement
    pxa_ssp_request()/free() in some central place that can be shared by the
    ACPI and PCI glue code.
    
    Instead of doing that we can make pxa_ssp_request()/free() to be available
    only when CONFIG_ARCH_PXA is set. On other arches these are being stubbed
    out in preference to passing the ssp_device from the platform data
    directly.
    
    We also change the SPI bus number to be taken from ssp->port_id instead of
    platform device id. This way the supporting code that passes the ssp can
    decide the number (or it can set it to the same as pdev->id).
