This patch series brings together patches [1] and [2] which introduce mclk0 clock source via DT. mclk0..3 are the four clock sources options of SAI's clock MUX. mclk0 option selects: - Bus Clock on i.MX8 - MCLK1 on i.MX6/7 Finally we also update the DT binding information for SAI clocks. In [1] and [2] Nicolin had a very good point on the fact that mclk0 might not be needed in the DT. Anyhow, there are two reasons for which I think mlck0 should be added to DT: 1) SAI clock source select MUX is really part of the hardware 2) flexibility! We let DT tell us which is the option for MUX option 0.
