[PATCH 2/3] ASoC: multi-component - Modify to use common S3C I2S features

[Seungwhan Youn]

In Samsung SoC's I2S was improved gradually from I2Sv2 to I2Sv4.
So, S3C I2S platform codes are designed to use privious feature
hierarchy. This patch modify that s3c64xx-i2s use common features
of s3c-i2s-v2 and remove duplicated function on s3c64xx-i2s.

We already have a driver for this in mainline (which you are modifying).
It looks like what you're actually doing is registering a device for the
AC'97 CODEC so things probe.

I'd really expect this to be being pulled from the resources for the
platform device for the DAI rather than hard coded into the driver.  If
we're going to start reorganising things like this and touching all the
drivers it'd seem better to go straight to doing that rather than
introducing this approach.

Does your comment means that 'i2s->base' get base address from the
resources for the platform device using 'platform_get_resources()'?
I'm doing on preparing that issue into another patch already (because
I think this patch is only for Liam's multi-comp, not for that issue).

If the resource should get from platform device, I'll be happy to make
a new one.


Thanks.

Claude.

Yes, exactly.

My comment was that since this patch is going so far towards doing the
move to pulling the data from the platform device it'd make sense to
just do that as part of this patch rather than introduce a temporary
workaround.  It's not really any extra effort and it's much nicer.

Okay,

I'll make a new patch-set that includes the data pulls from platform device.
Thank you for your advice. :-)
