Restore RockPI-S audio again

[brentr]

Description

Another batch of kernel changes broke Rockchip's RK3308 ASoC
See:
https://forum.armbian.com/topic/51825-no-audio-on-kernel-61215-and-armbian-2522-bookworm-minimal/

Documentation summary for feature / change

The main reason culprit was an ABI change caused by mainline kernel commit:
21cfbeae7d7c54a6cdea4b00096150f438f4fbde

That required clients to explicitly set sampling frequency, where it had defaulted before. This patch enhances the i2s driver such that it supplies the default sampling frequency whenever the client has not overridden it.

On 6.16, some long deprecated aliases, on which the RK3308 ASoC driver relied, were finally removed, requiring some symbols be renamed.

@paolosabatino had added an overlay to optionally enable the pcm5102a CODEC some time ago, but it didn't really work because the pcm5102a was included in the base DTC fixes patch for the PI-S. So, this patch also removes the pcm5102a support from the DTC fixes patch. The very few folks that have a pcm5102a CODEC must now enable the overlay for it.

How Has This Been Tested?

Tested on RockPI-S running current and edge branches with Debian Minimal.
With ROCK Pi S PoE HAT
playback: speaker-test, mpg321 of various mp3 tunes out headphone jack
record: Only the test described in the forum. I have no audio recording capability.

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai explain this code block.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and explain its main purpose.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Good. I'll test this patch on my board later.
