    spi: bcm53xx: driver for SPI controller on Broadcom bcma SoC · 0fc6a323
    Rafał Miłecki authored
    Broadcom 53xx ARM SoCs use bcma bus that contains various cores (AKA
    devices). If board has a serial flash, it's connected over SPI and the
    bcma bus includes a SPI controller. Example log from such a board:
    bus0: Found chip with id 53010, rev 0x00 and package 0x02
    (...)
    bus0: Core 18 found: SPI flash controller (manuf 0x4BF, id 0x50A, rev 0x01, class 0x0)
    
    This patch adds a bcma driver for SPI core, it registers SPI master
    controller and "bcm53xxspiflash" SPI device.
