[PATCH v2 1/5] ASoC: dapm: Skip CODEC<->CODEC links in connect_dai_link_widgets()

[PATCH v2 1/5] ASoC: dapm: Skip CODEC<->CODEC links in connect_dai_link_widgets()

[Lars-Peter Clausen]

For CODEC to CODEC DAI links the paths are created in snd_soc_dapm_new_pcm().
Also for CODEC to CODEC links the widgets are connected cross-over via a DAI
link widget, meaning that the capture widget of one CODEC will be connected to
the playback widget of the other and vice versa. Whereas
snd_soc_dapm_connect_dai_link_widgets() directly connects the playback widget of
the CPU DAI to the playback widget of the CODEC DAI and the capture widget of
the CPU DAI to the capture widget of the CODEC DAI. So not skipping
CODEC<->CODEC links in snd_soc_dapm_connect_dai_link_widgets() will create
incorrect connections between the two CODECs which will cause DAPM to detect
active paths where there are none and unnecessarily power up widgets.

Fixes: b893ea5 ("ASoC: sapm: Automatically connect DAI link widgets in DAPM graph.")

[PATCH v2 2/5] ASoC: Revert "ASoC: dapm: Fix double prefix addition"

[Lars-Peter Clausen]

This reverts commit bd23c5b661858446267f4d6b2fb4edd8eb710dda.

The patch claims that the patch is necessary to avoid double prefix addition
when calling snd_soc_dapm_add_route() from snd_soc_dapm_connect_dai_link_widgets().
But snd_soc_dapm_add_route() is called with the card's DAPM context, which does
not have a prefix, which means there is no prefix that could be added a second
time.

I might be missing something. My best guess is that this was needed in some
vendor tree, but not in upstream.

If we find a widget who's stream name matches the name of a DAI widget then
thats the one it should be connected to. Based on the widget id we can say in
which direction the path should be. No need to go back to the DAI and check the

I think you have removed all the uses of this variable (dai) so you can
remove this as well.

Hi Songhee, Arun,

Can you take a look at this? I think the reason why you had this patch is 
because this was needed to prevent double prefix addition in 
snd_soc_dapm_link_dai_widgets(). All other places where dapm_add_route() 
is/was used do not suffer the problem of double prefix addition. But 
snd_soc_dapm_link_dai_widgets() was changed in commit commit 2553628e 
("ASoC: dapm: Add snd_soc_dapm_add_path() helper function") to use 
dapm_add_path which does not have the problem since it doesn't try to add a 
prefix. v3.12 was the first kernel that had this commit and I think that you 
forward ported this change from a vendor tree that was based on an earlier 
version. So in summery I think the issue that you tried to fix this patch 
was already fixed by the time you submitted the patch.

Thanks,
- Lars

We tested the latest upstream kernel and it works without our patch. So, it's
okay to revert this and sorry to push this patch in the first place.
