[PATCH v2 0/6] ASoC: Add NTP8918 and NTP8835 codecs support

[Igor Prusov <ivprusov@xxxxxxxxxxxxxxxxx>]

This series adds support for two NeoFidelity amplifiers. For both
amplifiers vendor provides software for equalizer and filters
configuration, which generates firmware files with registers values.
Since in both cases those files have same encoding, a common helper
module is added to get firmware via request_firmware() API and set
registers values.
