eeprom: at24: convert magic numbers to structs
Fundamental properties such as capacity and page size differ among at24-type chips. But these chips do not have an id register, so this can't be discovered at runtime. Traditionally, at24-type eeprom properties were determined in two ways: - by passing a 'struct at24_platform_data' via platform_data, or - by naming the chip type in the devicetree, which passes a 'magic number' to probe(), which is then converted to a 'struct at24_platform_data'. Recently a bug was discovered because the magic number rounds down all chip sizes to the lowest power of two. This was addressed by a work-around commit 5478e478 ("eeprom: at24: correctly set the size for at24mac402"), with the wish that magic numbers should over time be converted to structs. This patch replaces the magic numbers with 'struct at24_chip_data'. Signed-off-by:Sven Van Asbroeck <svendev@arcx.com> Signed-off-by:
