    Subject[PATCH 0/7] atmel-spi: Allow using more than 4 GPIOs as CS
    Date
    Hello,

    the main purpose of this series is allowing to use more than 4 GPIOs
    as CS. But while doing it, I also clean-up the code and the comments
    to match the actual support of the hardware.

    Thanks to this series, it is now more clear to see what can be done
    with CS GPIO and native CS. It is also possible to mix native and GPIO
    CS as expected by the SPI binding.

    In the end even managment of the specific use case for CS0 on
    AT91RM9200 has been simplified.

    spi: atmel: Configure GPIO per CS instead of by controller
    spi: atmel: Remove useless private field
    spi: atmel: Remove platform data support
    spi: atmel: Improve and fix GPIO CS usage
