2015-07-29ASoC: rcar ctu: Staticise local symbolsLars-Peter Clausen1-1/+1
rsnd_of_parse_ctu() is not used outside this file so it can be static. Fixes the following sparse warning: sound/soc/sh/rcar/ctu.c:72:6: warning: symbol 'rsnd_of_parse_ctu' was not declared.

2015-07-17ASoC: rsnd: add MIX (Mixer) supportKuninori Morimoto8-13/+333
This patch adds MIX (Mixer) initial support for rsnd driver. It is assuming that this MIX is used via DPCM. This is sample code for playback.

2015-07-17ASoC: rsnd: add CTU (Channel Transfer Unit) prototype supportKuninori Morimoto8-6/+236
This patch adds CTU (Channel Transfer Unit) support for rsnd driver. But, it does nothing to data at this point, but is required for MIX support. CTU design is a little different from other IPs (CTU0 is including CTU00 - CTU03, and CTU1 is including CTU10 - CTU13, these have different register mapping) We need to care about it on this driver.

Current rsnd driver is assuming Audio DMAC / Audio DMAC peri peri are used from SSI/SSIU/SRC/DVC. But we will add CTU/MIX to this driver. Then, current DMA path searching method is not understandable, and good enough for this purpose. This patch update DMA path search method, more simply.

2015-07-16ASoC: rsnd: tidyup data align positionKuninori Morimoto4-15/+45
Sound L/R order of SSI is different from Linux sound data order. So current rsnd driver is using DALIGN (= data align) to exchange data align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted sound volume will be exchanged if user used volume control on DVC. Because SSIU which exchanges data align is located after DVC.

2015-07-04bluetooth: fix list handlingLinus Torvalds2-2/+3
Commit 835a6a2f8603 ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An.
