Hi Mark, All,
Just a question. Can you explain me the proper way to configure eq1 and
eq2 of max98089 using sound/soc/codecs/max98088.c driver?
Could be a valid solution fetching eq1, eq2 bands params from dts?
Let me know.
Thanks in advance
Tommaso

There's plenty of examples of equalisers in the code already. I don't
know how this specific device works but generally these are either
exposed as a series of volume like sliders or as binary controls. This
doesn't restrict people to settings from the firmware, making
development of new configuraitons much easier.

Thanks for your reply.
I meant somethings like this:
max98089: codec@10 {
#sound-dai-cells = <0>;
compatible = "maxim,max98089", "maxim,max98088";
reg = <0x10>;
clocks = <&clk IMX8MM_CLK_SAI3_ROOT>;
clock-names = "mclk";
/* eq1 cfg params */
eq1-cfg-dt-en;
eq1-band1 = /bits/ 16 <0x2000 0xC001 0x4000 0x005D 0x0000>;
eq1-band2 = /bits/ 16 <0x2C30 0xC01F 0x3DAA 0x03EC 0x111E>;
eq1-band3 = /bits/ 16 <0x0C41 0xC0BE 0x29AA 0x09B5 0x3094>;
eq1-band4 = /bits/ 16 <0x6671 0xC655 0x3036 0x1BC0 0x2A16>;
eq1-band5 = /bits/ 16 <0x538D 0xD64E 0x23BD 0x308D 0x3517>;
};

I understood what you meant, like I say this should be a runtime control.
