'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. This patch doesn't call rsnd_dai_pointer_update() under spin lock Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

clk_prepare_enable()/clk_disable_unprepare() uses mutex inside, in concretely clk_prepare()/clk_unprepare().And it uses __schedule(). Then, raw_spin_lock/unlock_irq() is called, and it breaks Renesas sound driver's spin lock irq. This patch separates thesse into clk_prepare()/clk_unprepare() and clk_enable/clk_disable. And call clk_prepare()/clk_unprepare() from probe/remove function. Special thanks to Das Biju.

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC). And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. dma-names on DT was implemented as no difference between 1st / 2nd DMAC's, since rsnd had assumed that both DMACs are implemented as DMAEngine. That style was "src_dst". But now, 2nd DMAC was implemented as non DMAEngine, and it doesn't need dma-names anymore. So, this dma-names rule is no longer needed. And additionally, dma-names was assumed that it has all (= SSI/SSIU/SRC/DVC) nodes under sound node. In upstream code, no SoC/platform is supporting DMA for rsnd driver yet. This means there is no compatible issue if this patch changes dma-names's rule of DT. This patch assumes dma-names for 1st DMAC are tx/rx base, and listed in each SSI/SRC/DVC subnode ex) rcar_sound,dvc { dvc0: dvc@0 { dmas = <&audma0 0xbc>; dma-names = "tx"; }; ... rcar_sound,src { src0: src@0 { ... dmas = <&audma0 0x85>, <&audma1 0x9a>; dma-names = "rx", "tx"; }; ... rcar_sound,ssi { ssi0: ssi@0 { ... dmas = <&audma0 0x01>, <&audma1 0x02>, <&audma0 0x15>, <&audma1 0x16>; dma-names = "rx", "tx", "rxu", "txu"; }; ...
