5 - compatible: should be one of the following
6    - "rockchip,px30-i2s-tdm": for px30
7    - "rockchip,rk1808-i2s-tdm": for rk1808
8    - "rockchip,rk3308-i2s-tdm": for rk3308
9    - "rockchip,rk3568-i2s-tdm": for rk3568
10    - "rockchip,rk3588-i2s-tdm": for rk3588
11    - "rockchip,rv1106-i2s-tdm": for rv1106
12    - "rockchip,rv1126-i2s-tdm": for rv1126
13 - reg: physical base address of the controller and length of memory mapped
15 - interrupts: should contain the I2S interrupt.
16 - dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
18 - dma-names: should include "tx" and "rx".
19 - clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
20 - clock-names: clock names.
21 - rockchip,bclk-fs: configure the bclk fs.
22 - resets: a list of phandle + reset-specifer paris, one for each entry in reset-names.
23 - reset-names: reset names, should include "tx-m", "rx-m".
24 - rockchip,cru: cru phandle.
25 - rockchip,grf: the phandle of the syscon node for GRF register.
26 - rockchip,mclk-calibrate: enable mclk source calibration.
27 - rockchip,clk-trcm: tx and rx lrck/bclk common use.
28    - 0: both tx_lrck/bclk and rx_lrck/bclk are used
29    - 1: only tx_lrck/bclk is used
30    - 2: only rx_lrck/bclk is used
31 - rockchip,no-dmaengine: This is a boolean property. If present, driver will do not
32   register pcm dmaengine, only just register dai. if the dai is part of multi-dais,
34   multi-dais usage.
35 - rockchip,playback-only: Specify that the controller only has playback capability.
36 - rockchip,capture-only: Specify that the controller only has capture capability.
39 - rockchip,i2s-rx-route: This is a variable length array, that shows the mapping
40   route of i2s rx sdis to I2S data bus. By default, they are one-to-one mapping:
41   * sdi_0 <-- data_0
42   * sdi_1 <-- data_1
43   * sdi_2 <-- data_2
44   * sdi_3 <-- data_3
47   * sdi_3 <-- data_0
48   * sdi_1 <-- data_1
49   * sdi_2 <-- data_2
50   * sdi_0 <-- data_3
52   - rockchip,i2s-rx-route = <3 1 2 0>;
54 - rockchip,i2s-tx-route: This is a variable length array, that shows the mapping
55   route of i2s tx sdos to I2S data bus. By default, they are one-to-one mapping:
56   * sdo_0 --> data_0
57   * sdo_1 --> data_1
58   * sdo_2 --> data_2
59   * sdo_3 --> data_3
62   * sdo_2 --> data_0
63   * sdo_1 --> data_1
64   * sdo_0 --> data_2
65   * sdo_3 --> data_3
67   - rockchip,i2s-tx-route = <2 1 0 3>;
69 - rockchip,tdm-fsync-half-frame: This is a boolean value, if present, use half
