It is completely unclear what you are doing in the SPI case. I deciphered it studying the driver. I shouldn't have to do that, your binding should make that clear.

So your DT must look like this:

i2c {
	codec@57 {
		compatible = "realtek,rt5575-use-spi";
		reg = <0x57>;
	};
};

spi {
	codec@1 {
		compatible = "realtek,rt5575";
		reg = <0x1>;
	};
};

First, there's no need for "-use-spi" because you can just check if there is a rt5575 SPI device and use it if there is. Why would you have the SPI device and not use it?

But really it is not ideal having 2 device nodes for a single device. It would be much simpler to just have something like this in the i2c node:

spi-parent = <&spi0 1>;

Where the cell is the chip-select #.

We have an 'i2c-parent' already for similar reasons when there are 2 bus connections.

The compatible realtek,rt5575-use-spi will be removed, and if there is no SPI device in the DTS, the warning message will be shown as "The hardware configuration should be with built-in flash".

Quoted 9 lines

But really it is not ideal having 2 device nodes for a single device. It would be much simpler to just have something like this in the i2c node:
spi-parent = <&spi0 1>;
Where the cell is the chip-select #.
We have an 'i2c-parent' already for similar reasons when there are 2 bus connections.

In the current kernel, I cannot find any function to obtain a struct spi_controller when no SPI device is defined in the DTS. This was possible in older kernels using the legacy spi_busnum_to_master(), but that function is no longer available in upstream.

Thanks,
Oder

Yeah, you may have to add something given 'spi-parent' doesn't exist yet. I don't think spi_busnum_to_master() would be quite right either. In any case, what the kernel supports or doesn't support doesn't matter from a binding perspective.

PATCH v9 2/2 ASoC: rt5575: Add the codec driver for the ALC5575

In reply to Oder Chiou

The ALC5575 integrates an audio DSP that typically loads its firmware from an external flash via its own SPI host interface. In certain hardware configurations, the firmware can alternatively be loaded through the SPI client interface. The driver provides basic mute and volume control functions. When the SPI client interface is enabled, firmware loading is handled by the SPI driver.
