Orange pi 5 plus issue with 3.5mm headset microphome

[Perechesov Vladimir]

It was found that 3.5mm jack has issue with using headset. Speakers are work good on my "uname -a Linux orangepi5-plus 6.19.0-rc5-edge-rockchip64 #1 SMP PREEMPT Mon Jan 12 03:03:14 UTC 2026 aarch64 aarch64 aarch64 GNU/Linux" system but micro is silent. By debugging it was found that register 0x2b(43) "DAC Control 21"  has difference between actually used es8388 on OP5+ and original driver's IC es8328. Also microphone bias was never activated by bits 2,3 in register 0x03. I create patch and now microphone work properly. I don't know how to properly share this patch so I will attache it here.

would you mind sending a pr or even upstream this change?

To be honest I don't know how to do this and even  more I am not sure in correctness of of my code in term of conventions. I mean that for example I add #define-s with names ES8388_xxx to header file ES8228 and so on.
