    clk: tegra: Fix maximum audio sync clock for Tegra124/210 · 845d782d
    Jon Hunter authored
    The maximum frequency supported for I2S on Tegra124 and Tegra210 is
    24.576MHz (as stated in the Tegra TK1 data sheet for Tegra124 and the
    Jetson TX1 module data sheet for Tegra210). However, the maximum I2S
    frequency is limited to 24MHz because that is the maximum frequency of
    the audio sync clock. Increase the maximum audio sync clock frequency
    to 24.576MHz for Tegra124 and Tegra210 in order to support 24.576MHz
    for I2S.
    
    Update the tegra_clk_register_sync_source() function so that it does
    not set the initial rate for the sync clocks and use the clock init
    tables to set the initial rate instead.
