2015-07-17ASoC: rsnd: add rsnd_src_initialize_lock/unlock()Kuninori Morimoto1-11/+11
Renesas SCU (Sampling Rate Convert Unit) includes SRC/CTU/MIX/DVC, and these have similar register. xxxIR (Initialization Register) is one of them. These xxxIR need be set to 1 during initialization. Current rsnd driver has src.c / dvc.c, and we will have mix.c. It is readable if these have same named function.

2015-07-17ASoC: rsnd: add rsnd_path_parse() for CTU/MIX/DVC route settingKuninori Morimoto3-31/+33
Current sound data route settings is done in dvc.c, and it doesn't care about CTU/MIX at this poinnt, but we need to care about these. OTOH, rsnd driver already has rsnd_path_xxx() functions for data path which are good match for CTU/MIX/DVC path selectio. This patch adds new rsnd_path_parse() to select sound data route which will care about CTU/MIX/DVC path.

HD-audio: - Continued code restructuring for the future ASoC driver; now HDA controller driver is split to a core helper module. - Preliminary codes for Skylake audio support in HDA core. - Proper i915 gfx power well management for SKL & co - Enabled runtime PM as default for Intel HDMI/DP codecs - Newer Tegra chip supports - More quirks for Dell headsets, Alienware (with CA0132), etc. - A couple of DRM ELD helper API functions ASoC: - Support for loading ASoC topology maps from firmware, intended to be used to allow self-describing DSP firmware images to be built which can map controls added by the DSP to userspace without the kernel needing to know about individual DSP firmwares - Lots of refactoring to avoid direct access to snd_soc_codec where it's not needed supporting future refactoring - Big refactoring, cleanup and enhancement for the Wolfson ADSP driver - Cleanup series for TI TAS2552 and R-CAR drivers - Fixes and improvements on RT56xx codecs - Support for TI TAS571x power amplifiers - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs - Support for x86 systems with RT5650 and Qualcomm Storm - Support for Mediatek AFE (Audio Front End) unit - Other various small fixes to ASoC codec drivers Firewire: - Enhanced to allow non-blocking streams to use timestamp synchronization - Improve support for DM1500 and BeBoBv3 Misc: - Cleanup of old pci API functions over all PCI sound drivers - Fix long-standing regression of the old powermac i2c setup" * tag 'sound-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (533 commits) ALSA: pcm: Fix pcm_class sysfs output ALSA: hda-beep: Update authors dead email address ASoC: wm_adsp: Move DSP Rate controls into the codec ASoC: wm8995: Fix setting sysclk for WM8995_SYSCLK_MCLK2 case ALSA: hda: provide default bus io ops extended hdac ALSA: hda: add hda link cleanup routine ALSA: hda: add hdac_ext stream creation and cleanup routines ASoC: rsrc-card: remove unused ret ALSA: HDAC: move SND_HDA_PREALLOC_SIZE to core ASoC: mediatek: Add machine driver for rt5650 rt5676 codec ASoC: mediatek: Add machine driver for MAX98090 codec ASoC: mediatek: Add AFE platform driver ASoC: rsnd: remove io from rsnd_mod ASoC: rsnd: move rsnd_mod_is_working() to rsnd_io_is_working() ASoC: rsnd: don't use rsnd_mod_to_io() on snd_kcontrol ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_src_xxx() ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_ssi_xxx() ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_dma_xxx() ASoC: rsnd: don't use rsnd_mod_to_io() on rsnd_get_adinr() ASoC: rsnd: add common interrupt handler for SSI/SRC/DMA ...
2015-06-24Merge branch 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-armLinus Torvalds1-2/+1
Pull clkdev updates from Russell King: "This series addresses some breakage in clkdev caused by a previous patch set from the clk tree which introduced per-user clk structures. This basically renamed the existing 'struct clk' to 'struct clk_hw', and introduced a new 'struct clk'. This change will break anyone using clk_add_alias() with the common clk code enabled. Thankfully, the intersection of users of clk_add_alias() and those using the common clk code is practically zero, but this is something which should be fixed to keep the code sane. The problem is that clk_add_alias() does this: r = clk_get(...); l = clkdev_alloc(r, ...); clk_put(...); which causes the alias to store a pointer to 'r', which has been freed. The original patch set tried to work around this problem incorrectly - at clk_get() time, it tried to convert the struct clk to a struct clk_hw, and then creating a new struct clk from that. Clearly, if the original struct clk has been freed, then we have a use-after-free bug. We have other places in the tree which do something similar, so this series also addresses those locations too. This series addresses this problem by converting clkdev to store and use the clk_hw pointer. This allows clk_get() to only have to create it's per-user struct clk from the clk_hw. We can also get to the desired clk_hw at clk_add_alias() or clk lookup creation time, when the struct clk is "alive". We also perform some cleanups of the code: - replacing looped calls to clkdev_add() with clkdev_add_table() - replacing open-coded lookup allocation (which should have been using clkdev_alloc()) and subsequent clkdev_add() with clkdev_create() - replacing open-coded clk_add_alias() with clk_add_alias()" * 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: clk: s2mps11: use clkdev_create() ASoC: migor: use clkdev_create() ARM: omap2: use clkdev_add_alias() ARM: omap2: use clkdev_create() ARM: orion: use clkdev_create() ARM: lpc32xx: convert to use clkdev_add_table() SH: use clkdev_add_table() clkdev: add clkdev_create() helper clkdev: const-ify connection id to clk_add_alias() clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h clkdev: drop __init from clkdev_add_table() clk: update clk API documentation to clarify clk_round_rate() clkdev: use clk_hw internally

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.

2015-06-16ASoC: rsnd: don't call snd_pcm_period_elapsed() under spin lockKuninori Morimoto4-5/+35
'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>
2015-06-16ASoC: rsnd: don't care under/over run error when PIOKuninori Morimoto1-7/+9
PIO is used only for checking data path / codec settings. And underrun is very normal when PIO mode. Let's don't care about under/over run error when PIO case. Otherwise, 1) too many HW restart happens, 2) some sounds which need much data transfer can't play since it falls into error detection method which was created for DMA transfer 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>

2015-05-22ASoC: rsnd: spin lock for interrupt handlerKuninori Morimoto4-10/+30
Renesas R-Car driver interrupt handler was not locked before. But now, SSI/SRC interrupt handler calls restart function which should be called under spin lock. Below error might happen witout this patch.

Current Renesas R-Car sound driver calls rsnd_dai_stream_init() when start, but it didn't call paired function. This patch adds rsnd_dai_stream_quit() for it. This is prepare for interrupt error status check feature support.
