[alsa-devel] ALSA BLE MIDI
by happy musicmaker 10 Jul '17

10 Jul '17

Is there development for Bluetooth (BLE) MIDI under Linux ? More and more devices now support BLE MIDI. I have an BLE USB adapter that works fine with many MIDI BLE devices but the devices don't shop up in ALSA (Ubuntu 17.04). It seems Linux only supports audio devices.

[alsa-devel] [PATCH] ALSA: pcm: Simplify check for dma_mmap_coherent() availability
by Takashi Iwai 10 Jul '17

10 Jul '17

We check the availability of dma_mmap_coherent() in hw_support_mmap() but with an ugly ifdef of lots of arch-checks. Now we have a nice CONFIG_ARCH_NO_COHERENT_DMA_MMAP kconfig, and this can be used together with CONFIG_HAS_DMA check for a cleaner and more comprehensive check.

[alsa-devel] [PATCH v8 0/5] Add platform clock for BayTrail platforms
by Pierre-Louis Bossart 10 Jul '17

10 Jul '17

These patches specifically enable the audio MCLK required by Baytrail CR devices. It is the remaining part of a bigger set of patches (already merged in Mark Brown's tree) that enable sound for Baytrail CR devices (especially Asus T100TAF) [1]. They include the clock driver and clock enabling in the pmc_atom code (along with moving of the non-architectural pmc_atom driver code into drivers/platform/x86 as suggested by Thomas Gleixner [2]). This move includes a new header in include/linux/platform_data/x86/. While there is an agreement that the definitions for PMC clocks are not really platform data this location is seen as a good-enough compromise with an agreement between Darren Hart and Andy Shevchenko [3] [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-August/111704.html [2] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-October/113936.ht… [3] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-December/115892.h… Changes from v7: - Replaced clk-readl/writel by regular readl/writel - Fixed two nitpick comments (newline and driver name string) - Fixed [5:0] to [0..5] in comment (missed in v6) Changes from v6: - Addressed comments from Stephen Boyd, Andy Shevchenko and Vinod Koul - Renamed clk-byt-plt to clk-pmc-atom - Rebase to 4.10-rc3 (broonie/for-next) - Added helper functions to make error handling more compact - Removed module-related code since it's not possible/supported - Removed useless tests on remove - PMC_CLK_OFFSET move to clk-pcm-atom (more logical) - Split typo correction and makefile fix in separate patches - small fixes (spaces, defaults in switches, alphabetical order, use of clk_writel/readl and no test on write, simpler error handling, use of while(i--), unsigned loop variables, kernel doc fields, format-patch -M -C -D, use of PLATFORM_DEVID_NONE) Changes from v5: - fix build error reported by kbuild test robot - split the clk driver code from x86 platform changes Changes from v4: - move the pmc_atom driver from arch/x86/platform/atom to drivers/platform/x86 Changes from v3: - replace devm_kzalloc with devm_kcalloc - add x86 architecture maintainers Changes from v2: - move clk platform data structures to a separate include file - store clk_hw pointer for the fixed rate clocks Changes from v1: - register the clk device as child of pmc device - pass iomem pointer from pmc driver to clk driver to avoid using pmc_atom_read()/write() and use readl/writel API instead - use devm_clk_hw_register/clkdev_hw_create instead of clk_register/clkdev_create Irina Tirdea (3): clk: x86: Add Atom PMC platform clocks arch/x86/platform/atom: Move pmc_atom to drivers/platform/x86 platform/x86: Enable Atom PMC platform clocks Pierre-Louis Bossart (2): clk: Make x86/ conditional on CONFIG_COMMON_CLK platform/x86: fix typo in comment arch/x86/Kconfig | 4 - arch/x86/platform/atom/Makefile | 1 - drivers/acpi/acpi_lpss.c | 2 +- drivers/clk/Makefile | 2 + drivers/clk/x86/Makefile | 1 + drivers/clk/x86/clk-pmc-atom.c | 371 +++++++++++++++++++++ drivers/platform/x86/Kconfig | 5 + drivers/platform/x86/Makefile | 1 + .../atom => drivers/platform/x86}/pmc_atom.c | 88 ++++- include/linux/platform_data/x86/clk-pmc-atom.h | 44 +++ .../linux/platform_data/x86}/pmc_atom.h | 2 +- 11 files changed, 506 insertions(+), 15 deletions(-) create mode 100644 drivers/clk/x86/clk-pmc-atom.c rename {arch/x86/platform/atom => drivers/platform/x86}/pmc_atom.c (87%) create mode 100644 include/linux/platform_data/x86/clk-pmc-atom.h rename {arch/x86/include/asm => include/linux/platform_data/x86}/pmc_atom.h (98%) -- 2.7.4

[alsa-devel] [PATCH v2] ASoC: rt5514: Move the auto disable DSP function to set_bias_level()
by Oder Chiou 10 Jul '17

10 Jul '17

Move the auto disable DSP function from the widget event "DAPM Pre" to the set_bias_level() function to avoid the unexpected behavior. While the SPI was recording using the DAI "rt5514-dsp-cpu-dai", the event "DAPM Pre" would be manipulated even the DAPM widgets were not connected, and it also would power off the DSP that cause the DSP buffered data lost. So the auto disable DSP function should move to the set_bias_level() function to make sure that it is only manipulated by the DAPM widgets are connected.
