    Subject[PATCH 1/7] MFD: Fix mc13xxx SPI regmap
    Date
    From: Philippe Rétornaz <philippe.retornaz@epfl.ch>

    This fix the SPI regmap configuration, the wrong write flag was used.
    Also, bits_per_word should not be set as the regmap spi implementation
    uses a 8bits transfert granularity.
