[alsa-devel] [PATCH] ASoC: pcm: allow delayed suspending request by users
by Vinod Koul 07 Jan '16

07 Jan '16

From: Sanyog Kale <sanyog.r.kale(a)intel.com> If a device would like to use delayed suspending then PM recommendation is to set ‘power.use_autosuspend’ flag. To allow users to do so we need to change runtime calls in core to use autosuspend counterparts. For user who do not wish to use delayed suspend not setting the device's ‘power.use_autosuspend’ flag will result in non-delayed suspend even with these APIs which incidentally is also the default behaviour, so only users will be impacted who opt in for this.

[alsa-devel] [PATCH 00/12] dw-hdmi development
by Russell King - ARM Linux 07 Jan '16

07 Jan '16

This sub-series is a mixture of development: * Removing the incorrect pixel repetition configuration code * Preventing pixel-doubled modes from being used * Adding interlaced video support * Implementing the sink_is_hdmi/sink_has_audio flags I suggested a few months ago * Only enabling audio support if the sink indicates it has audio * Avoiding double-enabling the HDMI interface * Fixing the mis-leading name of "dw_hdmi_phy_enable_power" * Adding connector mode forcing (important if your monitor bounces RXSENSE and HPD signals while in low-power mode.) * Improving the HDMI enable/disabling on sink status For review (and testing if people feel like it). Acks/tested-bys etc welcome. It applies on top of my drm-dwhdmi-devel branch, which is waiting for David Airlie to pull (see pull request on dri-devel, 15th July.) drivers/gpu/drm/bridge/dw_hdmi.c | 275 ++++++++++++++++++++++++++++++--------- drivers/gpu/ipu-v3/ipu-dc.c | 18 ++- drivers/gpu/ipu-v3/ipu-di.c | 129 +++++++++--------- 3 files changed, 291 insertions(+), 131 deletions(-) -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net.

[alsa-devel] [PATCH 0/4 v5] ALSA: dice: improve card registration processing
by Takashi Sakamoto 07 Jan '16

07 Jan '16

Hi, This patchset updates my previous one: [alsa-devel] [PATCH 0/5 v4] ALSA: dice: improve card registration processing http://mailman.alsa-project.org/pipermail/alsa-devel/2015-December/102504.h… Changes: * Merge patch 02 and 03 in v4. * Allocate sound card instance in sound card registration work, independently of dice instance, allocated in .probe callback and set as driver_data of device structure. * Use __be32 type for __be32 data. In this version, sound card instance is not allocated in .probe callback. In the callback, dice instance is allocated independently of the card instance. Thus, in .probe callback, this driver reserve no slot of sound card. The allocation of sound card instance is performed in a scheduled work. When processing in the work fails, the work can be re-scheduled again according to bus reset. Takashi Sakamoto (4): ALSA: dice: split subaddress check from category check ALSA: dice: postpone card registration ALSA: dice: purge transaction initialization at timeout of Dice notification ALSA: dice: expand timeout to wait for Dice notification sound/firewire/dice/dice-transaction.c | 123 +++++++++++------- sound/firewire/dice/dice.c | 227 +++++++++++++++++---------------- sound/firewire/dice/dice.h | 3 + 3 files changed, 202 insertions(+), 151 deletions(-) -- 2.5.0

[alsa-devel] [PATCH] ASoC: wm5110: Fix PGA clear when disabling DRE
by Charles Keepax 06 Jan '16

06 Jan '16

We don't want to use a bypassed write in wm5110_clear_pga_volume, we might disable the DRE whilst the CODEC is powered down. A normal regmap_write will always go to the hardware (when not on cache_only) even if the written value matches the cache. As using a normal write will still achieve the desired behaviour of bring the cache and hardware in sync, this patch updates the function to use a normal write, which avoids issues when the CODEC is powered down.

[alsa-devel] [PATCH v4 1/2] ASoC: wm_adsp: Add a handler for the compressed IRQ
by Charles Keepax 06 Jan '16

06 Jan '16

Here support is added for responding to DSP IRQs that are used to indicate data being available on the DSP. The idea is that we check the amount of data available upon receipt of an IRQ and on subsequent calls to the pointer callback we recheck once less than one fragment is available (to avoid excessive SPI traffic), if there is truely less than one fragment available we ack the last IRQ and wait for a new one. Signed-off-by: Charles Keepax <ckeepax(a)opensource.wolfsonmicro.com> --- Changes since v3: - Rename wm_adsp_buffer_ack_irq to wm_adsp_buffer_reenable_irq, and irq_ack to irq_count to make functionality more clear. - Remove the comment from wm_adsp_buffer_ack_irq that is no longer required with the new naming Thanks, Charles sound/soc/codecs/wm5110.c | 27 +++++++ sound/soc/codecs/wm_adsp.c | 188 +++++++++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/wm_adsp.h | 3 + 3 files changed, 218 insertions(+) diff --git a/sound/soc/codecs/wm5110.c b/sound/soc/codecs/wm5110.c index eb1e665..23b811c 100644 --- a/sound/soc/codecs/wm5110.c +++ b/sound/soc/codecs/wm5110.c @@ -2175,10 +2175,23 @@ static int wm5110_open(struct snd_compr_stream *stream) return wm_adsp_compr_open(&priv->core.adsp[n_adsp], stream);
