Tested-by: Mauro Carvalho Chehab <mchehab@xxxxxxxxxxxxxxx>

Tested on my Chromebook snow revision 5, with the following its file:

/dts-v1/;

/ {
    description = "Chrome OS kernel image with one or more FDT blobs";
    #address-cells = <1>;
    images {
        kernel@1{
	    description = "kernel";
            data = /incbin/("arch/arm/boot/zImage");
            type = "kernel_noload";
            arch = "arm";
            os = "linux";
            compression = "none";
            load = <0>;
            entry = <0>;
        };
        fdt@1{
            description = "exynos5250-snow.dtb";
            data = /incbin/("arch/arm/boot/dts/exynos5250-snow.dtb");
            type = "flat_dt";
            arch = "arm";
            compression = "none";
            hash@1{
                algo = "sha1";
            };
        };
        fdt@2{
            description = "exynos5800-peach-pi.dtb";
            data = /incbin/("arch/arm/boot/dts/exynos5800-peach-pi.dtb");
            type = "flat_dt";
            arch = "arm";
            compression = "none";
            hash@1{
                algo = "sha1";
            };
        };
        fdt@3{
            description = "exynos5250-snow-rev5.dtb";
            data = /incbin/("arch/arm/boot/dts/exynos5250-snow-rev5.dtb");
            type = "flat_dt";
            arch = "arm";
            compression = "none";
            hash@1{
                algo = "sha1";
            };
        };
    };
    configurations {
        default = "conf@1";
        conf@1{
            kernel = "kernel@1";
            fdt = "fdt@1";
        };
        conf@2{
            kernel = "kernel@1";
            fdt = "fdt@2";
        };
        conf@3{
            kernel = "kernel@1";
            fdt = "fdt@3";
        };
    };
};


After this patch, is is now properly detecting the audio chipset:

[    0.897587] max98090 7-0010: MAX98090 REVID=0x43
[    0.900135] max98090 7-0010: use default 2.8v micbias
