  • a3e86ed72   spi: rb4xx: Don't leak SPI master in probe error path ... Browse Code »

    commit a4729c3506c3eb1a6ca5c0289f4e7cafa4115065 upstream.

    If the calls to devm_clk_get(), devm_spi_register_master() or
    clk_prepare_enable() fail on probe of the Mikrotik RB4xx SPI driver,
    the spi_master struct is erroneously not freed.

    Fix by switching over to the new devm_spi_alloc_master() helper.

  • 4a1ae8be4   spi: rb4xx: Fix set_cs logic. ... Browse Code »

    As it turns out, the set_cs() enable parameter refers to the logic level
    on the CS pin, not the state of chip selection.

    This broke functionality of the LEDs behind the CPLD, or at least delayed
    the commands until another one came in to toggle CS.

  • 05aec3578   spi: Add SPI driver for Mikrotik RB4xx series boards ... Browse Code »

    This driver mediates access between the connected CPLD and other devices
    on the bus.

    The m25p80-compatible boot flash and (some models) MMC use regular SPI,
    bitbanged as required by the SoC. However the SPI-connected CPLD has
    a two-wire mode, in which two bits are transferred per SPI clock
    cycle. The second bit is transmitted with the SoC's CS2 pin.
