[PATCH v5 0/2] ASoC: mt8183: fix audio playback slowly after playback

[Jiaxin Yu]

This series patches add reset controller for MT8183, and audio will use it in 
machine driver during bootup, they depend on the for-next.

v5 changes:
	1. Add Signed-off-by tag and Reviewed-by tag.

v4 changes:
	1. Fixed wrong signed-off as correct mail suffix.
	2. Fixed patch subject that add patch version.

v3 changes:
	1. https://patchwork.kernel.org/patch/11164283/ and 
	   https://patchwork.kernel.org/patch/11164305/ has been merged.
	2. Change the name of mtk_wdt_compatible to mtk_wdt_data.
	3. Remove toprgu_reset struct and use mtk_wdt_dev instead.
	4. Get the value of sw_rst_num from .h file.
	5. Adddd mt2712-resets.h for mt2712.
	6. Improve commit message.

v2 changes:
	1. remove "WIP" that in the title of patches
	2. add hyper link for the patch that depends on
	3. patchwork list:
		https://patchwork.kernel.org/cover/11164285/
		https://patchwork.kernel.org/patch/11164295/

I keep wondering why your series does not show up in the watchdog patchwork.
Turns out that is not surprising, since you don't copy the watchdog mailing
list. That all but guarantees that it gets lost from my workflow. That is
kind of interesting - there are lots of lists in Cc:, but the two lists
that matter because maintainers need to review it (watchdog and devicetree)
are missing.

Anyway, comment and question below.

Is that (still) correct ? After all, behavior is different for those two now.
Just wondering.

Setting rcdev->nr_resets to 10 will make the check in
of_reset_simple_xlate() fail for MT2712_TOPRGU_APMIXED_SW_RST.

Same here. If the driver uses the default of_xlate function, this has to
be larger than the index of the last reset.
