[alsa-devel] [trivial PATCH] treewide: Align function definition open/close braces
by Joe Perches 19 Dec '17

19 Dec '17

Some functions definitions have either the initial open brace and/or the closing brace outside of column 1. Move those braces to column 1. This allows various function analyzers like gnu complexity to work properly for these modified functions.

[alsa-devel] [PATCH for-4.15] ASoC: rt5514-spi: only enable wakeup when fully initialized
by Brian Norris 19 Dec '17

19 Dec '17

If an rt5514-spi device is probed but the platform hasn't linked it in, we might never fully request the SPI IRQ, nor configure the rt5514 DSP, but we still might try to enable the SPI IRQ (enable_irq_wake()). This is bad, and among other things, can cause the interrupt to trigger every time we try to suspend the system (e.g., because the interrupt trigger setting was never set properly). Instead of setting our wakeup capabilities in the SPI driver probe routine, let's wait until we've actually requested the IRQ. Fixes issues seen on the "kevin" Chromebook (Samsung Chromebook Plus). Fixes: 58f1c07d23cd ("ASoC: rt5514: Voice wakeup support.") Signed-off-by: Brian Norris <briannorris(a)chromium.org> --- The patch that introduced the wakeup was in 4.15-rc1. I think this qualifies as a bugfix, and should probably go into 4.15.

[alsa-devel] [PATCH 00/10] ASoC: fsl_ssi: Clean up - coding style level
by Nicolin Chen 19 Dec '17

19 Dec '17

==Background== The fsl_ssi driver was designed for PPC originally and then it has been updated to support different modes for i.MX Series, including SDMA, I2S Master mode, AC97 and older i.MXs with FIQ, by different contributors for different use cases in different coding styles. Additionally, in order to fix/work-around hardware bugs and design flaws, the driver made a lot of compromise so now its program flow looks very complicated and it's getting hard to maintain or update. So I am going to clean up the driver in both coding style level and program flow level. ==Introduction== This series of patches is the first set to clean up fsl_ssi driver in the coding style level. Any patch here is not supposed to change the program flow. ==Verification== Theoretically, it only needs code review, build and sanity tests. I have done build and sanity tests on an i.MX 6 platform by building using imx_v6_v7_defconfig and testing with I2S slave/master mode.

For those which can only get approximation PLL out cases, this patch will use higher resolution to get a better PLL parameter.

Having both depends and select on the top-level is OK. The only problem is when an item that is selected by others has another depends. For example, a simple-looking case like below is actually buggy: config BAR tristate depends on X config FOO tristate "foo" select BAR Here BAR would be enabled by FOO no matter what X is, even if X=n. That said, when an item is selected, its own dependency is ignored. For correcting this, the depends-on-X must be moved to the top-level who selects the item: config BAR tristate config FOO tristate "foo" depends on X select BAR Note that the reverse-select chain works as expected. The breakage is only the mixture of select and depends in the selected items. Takashi

[alsa-devel] [PATCH] ASoC: amd: Adds rate and channel constraints for capture in Stoney rt5645

Constraints are added as we support 48Khz and dual channels.

[alsa-devel] [alsa-lib][PATCH v3 0/4] add SNDRV_PCM_FORMAT_{S, U}20
by Maciej S. Szmigiero 19 Dec '17

19 Dec '17

This format is similar to an existing 20-bit PCM format SNDRV_PCM_FORMAT_{S,U}20_3, however it occupies 4 bytes instead of 3. Changes from v1: Split the monolithic submission into separate commits. (Note that v2 wasn't tagged as such.) Changes from v2: Add commas at the end of two possible last entries of the snd_pcm_format_t enum so diffs will be more readable when new PCM formats are added in the future, remove asserts from snd_pcm_linear_{get,put}_index(). Maciej S. Szmigiero (4): asound.h: add SNDRV_PCM_FORMAT_{S,U}20 pcm: add and describe SND_PCM_FORMAT_{S,U}20 pcm: linear, route: handle linear formats with 20-bit sample on 4 bytes pcm: plug: add SND_PCM_FORMAT_{S,U}20 to linear_preferred_formats include/pcm.h | 20 ++++++++++++++++++-- include/sound/asound.h | 9 +++++++++ src/pcm/pcm.c | 10 ++++++++++ src/pcm/pcm_linear.c | 14 +++++++++++--- src/pcm/pcm_local.h | 4 ++++ src/pcm/pcm_misc.c | 41 ++++++++++++++++++++++++++++++++++++++--- src/pcm/pcm_plug.c | 11 +++++++++++ src/pcm/pcm_route.c | 6 ++++-- src/pcm/plugin_ops.h | 50 ++++++++++++++++++++++++++++++++++++++++++++++---- 9 files changed, 151 insertions(+), 14 deletions(-)
