2015-06-16ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_get_adinr()Kuninori Morimoto
Each Renesas sound mod (= SSI/SRC/DVC) might be called from many paths if it supports MIXer. In such case, mod <-> io is no longer 1:1 relationship.

Each Renesas sound mod (= SSI/SRC/DVC) might be called from many paths if it supports MIXer. In such case, mod <-> io is no longer 1:1 relationship. This means we can't use rsnd_mod_to_io() in SSI/SRC/DMA interrupt handler. In such case, we need to check all io in interrupt handler, and then, "priv" is needed.

2015-06-16ASoC: rsrc-card: cleanup for DPCMKuninori Morimoto
rsrc-card driver is based on simple-card driver which is caring about CPU / Codec connection. OTOH, rsrc-card is used for DPCM system. FE portion is constituted by CPU and dummy Codec, and BE is constituted by dummy CPU and Codec in DPCM system. Because of this, current rsrc-card is doing pointless method. It works well if FE/BE was 1:1, but not good for multi FE/BE. This patch cleanups rsrc-card driver for DPCM. and this is prepare for MIX support for Renesas sound driver.

'a9e1ac1a9e4585b5("ASoC: rsnd: spin lock for interrupt handler")' added spin lock under interrupt handler to solve HW restart issue. OTOH, current rsnd driver calls snd_pcm_period_elapsed() from rsnd_dai_pointer_update(). but, it will be called under spin lock if SSI was PIO mode. If it was called under spin lock, it will call snd_pcm_update_state() -> snd_pcm_drain_done(). Then, it calls rsnd_soc_dai_trigger() and will be dead-lock.

2015-04-11ASoC: rnsd: fix build regression without CONFIG_OFArnd Bergmann
The r-car sound driver only works when CONFIG_OF is set, and after a recent change has a compile-time dependency as well: sound/built-in.o: In function `rsnd_dma_request_channel': :(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel' This could be fixed either by adding a static inline wrapper for the function, or by adding a Kconfig dependency. This implements the second approach, which seems appropriate because the driver in fact has a hard dependency.
