06c8eb9a91 ASoC: mxs: Add missing MODULE_LICENSE("GPL")
The sound driver refuses to load as module, because of the missing
MODULE_LICENSE("GPL").
The file header indicates that the driver is indeed published under
the GPL.

778825801d ASoC: mxs-saif: remove function in platform_data
Add master_mode and master_id in platfrom_data since it's board
specific and board knows it.
Then we can remove the function pointer in platfrom_data to make
the driver more devicetree friendly.

85e7652d89 ASoC: Constify snd_soc_dai_ops structs
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.

The patch was generated with the following coccinelle semantic patch:
// <smpl>
@@
identifier ops;
@@
-struct snd_soc_dai_ops ops =
+const struct snd_soc_dai_ops ops =
{ ... };
// </smpl>

226d0f22d0 ASoC: keep pointer to resource so it can be freed
Add a new variable for storing resources accessed subsequent to the one
accessed using request_mem_region, so the one accessed using
request_mem_region can be released if needed.

The resource variable names are also changed to be more descriptive.

This code is also missing some calls to iounmap.

The semantic match that finds this problem is as follows:

identifier f;
statement S1,S2,S3;

76067540c6 ASoC: mxs-saif: add record function
1. add different clkmux mode handling
SAIF can use two instances to implement full duplex (playback &
recording) and record saif may work on EXTMASTER mode which is
using other saif's BITCLK&LRCLK.

The clkmux mode could be set in pdata->init() in mach-specific code.
For generic saif driver, it only needs to know who is his master
and the master id is also provided in mach-specific code.

2. support playback and capture simutaneously however the sample
rates can not be different due to hw limitation.

0bb98ba2b0 sound/soc/mxs/mxs-saif.c: add missing kfree
Move the test on pdev->id before the kzalloc to avoid requiring kfree when
the test fails.  This fix was suggested by Wolfram Sang.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>

identifier x;
expression E1!=0,E2,E3,E4;
statement S;

 }
... when != x = E2
    when != I(...,x,...) S
if (...) { ... when != x = E4
 kfree(x); ... return ...; }

bbe8ff5e25 ASoC: mxs-saif: clear clk gate first before register setting
Saif needs clear clk gate first before writing registers or the write
will not success.

The original xx_get_mclk function clear clk gate after mclk setting
that may cause the former mclk setting unwork, then the real output
mclk maybe inaccurate.
Placing the clear before setting mclk to avoid such an issue.

We also have to clear clk gate in startup instead of in prepare function.

fcb5e47eff ASoC: mxs: add mxs-sgtl5000 machine driver
The driver only supports playback firstly.
For recording, as we have to use two saif instances to implement full
duplex (playback & recording) due to hardware limitation, we need to
figure out a good design to fit in ASoC.
