[d-kernel] [PATCH 09/33] ASoC: codecs: ES8326: Changing initialisation and broadcasting

[kovalev@altlinux.org]

From: Zhu Ning <zhuning0077@gmail.com>

commit fc702b2c04d778d7e3a4091ebe54a86c5d0a0d96 upstream.

New chip versions require new initialisation and playback processes.
Changing the initialisation and playback process for better results.
The old chip versions are going to work well with the new sequences.
We've tested this with version_v0 and version_v3 chips
under the new sequence and they both pass.
