It is used to select whether the clock source of the spdif output is cts_amclk (when data are taken from i2s buffer) or the cts_mclk_i958 (when data are taken from the spdif buffer). The setup for this clock is identical to GXBB, so this ports commit 7eaa44f6207fb6 ("clk: meson: gxbb: add cts_i958 clock") to the Meson8/Meson8b/Meson8m2 clock driver.
