Samsung has three i2s drivers one for s3c24xx, one for s3c2412 and one
for rest of the platforms. The above mentioned other platforms has
Version 3/4/5 of i2s controllers. This dt binding is for for the i2s
driver that has support for Version 3/4/5 of i2s controller. So
"samsung,i2s-v5" is okay as compatible name? Please suggest me.
