This is a rebased version with the build break fixed and added Krzysztof's Acks. My apologies, I double checked there is no build errors between patches this time.
Below is cover letter text from v2.
This series restores support for the secondary CPU DAI in samsung/i2s.c driver and adds support for secondary CPU DAI on Odroid boards.
I have added 4 more clean up patches comparing to first version of the patch set (16/22...19/22).
The first patch adds new platform device for the secondary PCM, I tried to avoid registering new platform device in probe() as it doesn't play well with deferred probing but couldn't find a way to avoid that new device, unique devices are needed to register "PCM" components for each CPU DAI.
Patches 2/21...11/21 are mostly a clean up, following conversion to single component with multiple DAIs, allowing to reference both primary/secondary DAI in DT.
The patch set has been tested on Odroid U3, XU3, XU4 and Mini2440 (s3c2440 non-DT) boards.
Changes since v1 ((addressing Krzysztof's review comments): - added a comment, whitespace change in patch 1/21 - dropped unnecessary new line addition from patch 1/21
