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, 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 it does not correctly handle receiving those two clocks via the .set_sysclk op. Patch 5 fixes that. However the simple-audio-card and audio-graph-card sound card drivers do not support calling .set_sysclk twice, thus patch 6 makes the .init op of struct asoc_simple_priv overridable by a driver in order to be able to call .set_sysclk twice and thus configure both clocks. Patch 7 adds the codec driver and patch 8 builds on top of all the above by implementing a simple RK3308-specific audio card, based on audio-graph-card. This card sets all the I2S input clocks. Patches 1-2 add DT bindings for the codec and the card. Patches 3-4 add to the SoC DT file two I2S controllers (those which are internally connected to the internal codec) and the codec itself.
