    Subject[PATCH v4 12/18] ARM: davinci: dm365-evm: use device properties for at24 eeprom
    Date
    From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

    We want to work towards phasing out the at24_platform_data structure.
    There are few users and its contents can be represented using generic
    device properties. Using device properties only will allow us to
    significantly simplify the at24 configuration code.

    Remove the at24_platform_data structure and replace it with an array
    of property entries. Drop the byte_len/size property, as the model name
    already implies the EEPROM's size.
