This series adds power management support for Intel soundwire links.

I had applied except 3 & 9 (few skipped in middle due to conflict while
applying), BUT I get a build failure on patch 2 onwards :(

drivers/soundwire/intel_init.c: In function ‘sdw_intel_cleanup’:
drivers/soundwire/intel_init.c:72:4: error: implicit declaration of function ‘pm_runtime_disable’ [-Werror=implicit-function-declaration]
    72 |    pm_runtime_disable(&link->pdev->dev);

I suspect due to missing header? I was on x64 build with allmodconfig

So only patch 1 is applied and pushed now

I just tried on these series applied on top of soundwire/next

commit 9b3b4b3f2f2af863d2f6dd65afd295a5a673afa2 (soundwire/next)

    soundwire: intel: Add basic power management support

And I don't see any issue?

If you want to double-check merge issues, I pushed the code here: https://github.com/plbossart/sound/tree/sdw/pm_runtime_soundwire_next

I am really not sure what conflicts you are referring to, git am worked fine for me, only skipped the first patch that's already applied.

I tried the compilation twice, once with our default SOF config and once with allmodconfig.
