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
