    ARM: davinci: da8xx_register_spi() should not register SPI board info · 0273612c
    Vivien Didelot authored
    Without this patch, da8xx_register_spi() registers the SPI board info,
    the SPI controller, and sets its number of chipselect to the size of the
    static spi_board_info array. This is bad because a SPI board info may
    declare devices for different SPI buses, and because other code can also
    call spi_register_board_info() (e.g. a daughter board might provide
    additional SPI devices).
    
    This patch removes the spi_register_board_info() call from
    da8xx_register_spi(), renames this last one to da8xx_register_spi_bus()
    to be more explicit, takes the number of chipselect as a function
    parameter, and updates the impacted board-da8{3,5}0-evm.c, and
    board-mityomapl138.c files accordingly. It also sets the SPI platform
    data static, as it doesn't need to be exported.
