[PATCHv2,0/6] ASoC: da7213: support for usage with simple-card

Hi,

This extends the da7213 driver to be used with simple-audio-card in
combination with a fixed clock. Here is a snippet of the downstream
board's DT, that is supposed to be supported by this patchset.

---------------------------------------------------------------------
/ {
	sound {
		compatible = "simple-audio-card";
		simple-audio-card,name = "audio-card";
		simple-audio-card,format = "i2s";
		simple-audio-card,bitclock-master = <&dailink_master>;
		simple-audio-card,frame-master = <&dailink_master>;

		simple-audio-card,widgets = "Speaker", "Ext Spk";
		simple-audio-card,audio-routing = "Ext Spk", "LINE";

		simple-audio-card,cpu {
			sound-dai = <&ssi1>;
		};

		dailink_master: simple-audio-card,codec {
			sound-dai = <&codec>;
		};
	};


	clk_ext_audio_codec: clock-codec {
		compatible = "fixed-clock";
		#clock-cells = <0>;
		clock-frequency = <12288000>;
	};
};

&i2c1 {
	codec: audio-codec@1a {
		compatible = "dlg,da7212";
		reg = <0x1a>;
		#sound-dai-cells = <0>;
		VDDA-supply = <&reg_2v5_audio>;
		VDDSP-supply = <&reg_5v0_audio>;
		VDDMIC-supply = <&reg_3v3_audio>;
		VDDIO-supply = <&reg_3v3_audio>;
		clocks = <&clk_ext_audio_codec>;
		clock-names = "mclk";
	};
};
---------------------------------------------------------------------

Changes since PATCHv1:
 * https://lore.kernel.org/alsa-devel/[e-mail]/
 * add patch adding da7212 compatible to DT bindings
 * update regulator patch, so that VDDA is enabled together with VDDIO
   while the device is enabled to avoid device reset
 * update clock patch, so that automatic PLL handling is not enabled
   when PLL is configured manually
 * update clock patch, so that automatic PLL is disabled when the device
   is suspended
 * update clock patch, so that automatic PLL is configured into bypass
   mode when possible
