[alsa-devel] [PATCH 0/4] ASoC: Blackfin updates
Hi Mark and Takashi:
We updates the patchset: - split out AD1980 change to a seperated patch - coding style change
Thanks -Bryan

We added multi-channel function to this codec driver and Blackfin ASoC driver as well. It was tested on Blackfin hardware.

The changelog entry is now inaccurate since this was split out from the machine. This looks mostly OK but...
- /*power on LFE/CENTER/Surround DACs*/
- ext_status = ac97_read(codec, AC97_EXTENDED_STATUS);
- ac97_write(codec, AC97_EXTENDED_STATUS, ext_status&~0x3800);
...this should have spaces around the & - I'm rather surprised that checkpatch.pl doesn't pick that up (I just tested and it doesn't). Otherwise,

This patch provides a option for users to enable multi-channel function support in Blackfin ASoC driver. Because Blackfin is without MMU, it is easy for us and the user to enable this function at compiling stage not dynamically on the fly.

This patch provides a option for users to enable multi-channel function support in Blackfin ASoC driver. Because Blackfin is without MMU, it is easy for us and the user to enable this function at compiling stage not dynamically on the fly.

A few comments below, though.
As a general comment it'd be really helpful if you could split your changes into more patches than you tend to do - ideally, each patch should have a single logical change in it which is fully described by the commit message. Sometimes it's not worth splitting stuff out if the changes overlap but it does make review easier if you can.
For example, you've already split out the codec driver change but still well as the advertised change this patch also renames the mmap() support define and some coding style cleanups.

I'm not sure that the reindentation here is helpful but then the line is so long that it's hard to do anything. When revisiting this I'd suggest using temporary variables to calculate the pointers passed in - that should help a lot and I'd not expect worse code from the compiler since the value has to be calculated and stored for passing to the function anyway.

Normally just ifdef.

- Setting the TFS pin selector for SPORT 0 based on whether the selected port id F or G. If the port is F then no conflict should exist for the TFS. When Port G is selected and EMAC then there is a conflict between the PHY interrupt line and TFS. Current settings prevent the conflict by ignoring the TFS pin when Port G is selected. This allows both ssm2602 using Port G and EMAC concurrently.
- some code cleanup
