Subject: [PATCH 1/2] clk: rockchip: add I2S internal clock IDs for rk3288
To minimize jitter on the I2S clocks, it is important that the
denominator in the fractional divider is much greater than the
numerator. Add identifiers for these internal clocks so that the
specific clock topology and rates can be specified in the device tree.
