This codec is internally connected to the I2S peripherals on the same chip, and it has some peculiarities arising from that interconnection. For proper bidirectional operation with the internal codec at any possible combination of sampling rates, the I2S peripheral needs two clock sources (tx and rx), while connection with an external codec commonly needs only one. Since v5.16 there is a driver for the I2S in sound/soc/rockchip/rockchip_i2s_tdm.c, but in some cases it does not configure correctly the clocks, resulting in an unnecessarily inaccurate rate. Patch 1 fixes this. Patches 2-4 add the codec driver along with the bindings and a new helper macro. Patches 5-7 add to the SoC DT file two I2S controllers (those which are internally connected to the internal codec) and the codec itself and enable the driver in the ARM64 defconfig.
