    i3c: fix i2c and i3c scl rate by bus mode · ecc8fb54
    Vitor Soares authored Jun 19, 2019
    Currently the I3C framework limits SCL frequency to FM speed when
    dealing with a mixed slow bus, even if all I2C devices are FM+ capable.
    
    The core was also not accounting for I3C speed limitations when
    operating in mixed slow mode and was erroneously using FM+ speed as the
    max I2C speed when operating in mixed fast mode.
    
    Fixes: 3a379bbc
