Field usrcnt is unsigned so it cannot be lesser than zero. The patch fixes the check, moves it to the beginning of the function and changes return value to -EIO in case of usercnt error. The problem has been detected using proposed semantic patch scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1]. [1]: http://permalink.gmane.org/gmane.linux.kernel/2038576Signed-off-by:

This patch adds Multi channel support on Renesas R-Car sound. This patch is tested on Salvator-X board, but it can't use Multi channel, because supported format is different between codec chip and R-Car. Thus, it was tested on board which doesn't mount codec chip, with oscilloscope. Signed-off-by:

Current rsnd driver is using complex macro to parse DAI connection. This patch adds new rsnd_parse_connect_common() and replace current macro to it. This is prepare for multi channel support Signed-off-by:

TDM will use 6 or 8 slots on 1 SSI, and Multi channel will use 6 or 8 slots on few SSI (each SSI uses 2 slots). Thus, this adds new slot control functions which can be prepare for Multi channel support. Signed-off-by:

rsnd_get_slot_rdai() returns total slots (it returns 6 if total 6 channels) , and rsnd_get_slot_extend() returns extended SSI width (it returns 8 if total 6 channels). This will be used on SSI multi channel support too (It will return 2 if total 6 channels with 3 SSI). But, it is using confusable naming. This patch changes rsnd_get_slot_rdai() -> rsnd_get_slot(), rsnd_get_slot_extend() -> rsnd_get_slot_width() Signed-off-by:

Renesas sound driver has rsnd_get_adinr_bit/chan() functions. It is assuming _bit() returns ADINR :: OTBL, and _chan() returns ADINR :: CHNUM. Current _bit() returns both OTBL and CHNUM. This patch fixup it. Signed-off-by:

rsrc-card is DPCM supported version of simple-card. Thus it has similar DT format. OTOH, snd_soc_dai_link requests cpu/codec, but one of them will be snd-soc-dummy in DPCM case, and DPCM requests frontend/backend dai_link. This means it might have multi backend/codec. And, SND_SOC_DAIFMT_xxx is based on "codec". Because of these difference, current rsrc card can't detect correct dai_fmt. This patch detect correct dai fmt from 1st "codec". Signed-off-by:

We use ret as the return value from the rsnd_mix_probe() but if there are no child nodes and no errors then we will never initialize ret leading to build warnings. Ensure ret is initialized before we iterate over the child nodes to avoid this. Signed-off-by: -

L/R channel data has been treated as inverted on R-Car sound 16bit mode, Thus, 4689032b("ASoC: rsnd: tidyup data align position") tidyuped data align position. But it couldn't care about capture case. This patch cares both playback/capture Signed-off-by:

Renesas R-Car can out TDM by 1) 6ch x 1 DAI as TDM Extend Mode 2) 2ch x 4 x 1 DAI as TDM split Mode 3) 2ch x 3 DAI or 2ch x 4 DAI as TDM Multichannel Mode This patch adds 1) TDM Extend Mode. Because of HW design, this 6ch data will be outputed via 8ch data width. Signed-off-by:

Current SSI is assuming that the sound is always stereo. But, SSI needs to calculate its frequency when master mode. Then This frequency depends on each SSI's slots, and TDM mode (= TDM Extend Mode, TDM split Mode, TDM Multichannel Mode). This patch enables to use non-stereo sound. Signed-off-by:

It will have TDM settings on SSIWSR. Actually, we would like to set it on rsnd_ssi_config_init(), but we can't. Because SSI might be used as clock master (It doesn't need to call rsnd_ssi_config_init() when clock master mode). This patch adds new ssi->wsr and set it on rsnd_ssi_start(). Signed-off-by:
