From: Fabio Estevam <[email protected]> Introduce CONFIG_SYS_FSL_PMIC_I2C_LENGTH to configure the number of bytes that are used to communicate with the PMIC via I2C.
Instead of hardcoding the value, pass the number via a config option. This will be useful for adding support for PMIC MC34704 from Freescale, which uses only one byte in its I2C protocol.
