Q: this thread is about the patch for the pxa2xx-spi where the num_chipselect was raised by one to so that the slave connects here at all. otherwise the cs1 >= max will be hit. Do you think the bus_number is ok ? And shouldn't it be set the cs1=0 and num_chipselect=1 ?? The DSDT has wrongly SPI=1 as chipselect, either the firmware (DSDT) must be updated or a correct patch enables the spi master/slave init here. I hope or expect that when the spi slave will be init correctly, that the device would also work. The ACPI stuff is already done here, and I am running out of time. In the last resort I have to give up or have to do that at night :) cheers chris

[alsa-devel] [PATCH V5 1/2] ACPI / EC: Fix broken 64bit big-endian users of 'global_lock'
by Viresh Kumar 04 Oct '15

04 Oct '15

global_lock is defined as an unsigned long and accessing only its lower 32 bits from sysfs is incorrect, as we need to consider other 32 bits for big endian 64-bit systems. There are no such platforms yet, but the code needs to be robust for such a case. Fix that by changing type of 'global_lock' to u32.

by yitian 03 Oct '15

Designware I2S uses tx empty and rx available signals as the DMA handshaking signals. during music playing, if XRUN occurs, i2s_stop() function will be executed and both tx and rx irq are masked, when music continues to be played, i2s_start() is executed but both tx and rx irq are not unmasked which cause I2S stop sending DMA handshaking signal to DMA controller, and it finally causes music playing will be stopped once XRUN occurs for the first time.

[alsa-devel] Kernel Device Tree entries for simple-audio-card
by Rick Mann 03 Oct '15

03 Oct '15

Hi. I've built a Beaglebone Black Cape that has, among other things, a TI Audio CODEC on it (TLV320AIC3104). This is the same CODEC as the BBB Audio Cape (http://elinux.org/CircuitCo:Audio_Cape_RevB), and it's connected in almost the exact same way. The last few days I've been figuring out the Device Tree overlay needed to get Linux (4.1.4) to recognize it. It's finding the device and instantiating the low-level driver (tlv320aic3x-codec), although I'm not sure at this point if it's actually talking to it (I have verified that low-level i2c commands do work). But when it comes to the sound card setup, I'm having trouble getting the Device Tree right. I'm hoping someone on this list can offer some insight. The DT is here: https://github.com/JetForMe/podtique/blob/master/bbb/cape/Podtique1/BB-ENAB… And this is dmesg when I try to load that (note the name of my overlay is BB-ENABLE-PRU, which is an artifact of the experimentation I've been doing; it'll change to something more appropriate): [ 65.859275] bone_capemgr bone_capemgr: part_number 'BB-ENABLE-PRU', version 'N/A' [ 65.859318] bone_capemgr bone_capemgr: slot #4: override [ 65.859336] bone_capemgr bone_capemgr: Using override eeprom data at slot 4 [ 65.859355] bone_capemgr bone_capemgr: slot #4: 'Override Board Name,00A0,Override Manuf,BB-ENABLE-PRU' [ 65.859488] bone_capemgr: bone_capemgr bone_capemgr: slot #4: Requesting part number/version based 'BB-ENABLE-PRU-00A0.dtbo [ 65.859506] bone_capemgr: bone_capemgr bone_capemgr: slot #4: Requesting firmware 'BB-ENABLE-PRU-00A0.dtbo' for board-name 'Override Board Name', version '00A0' [ 65.861105] bone_capemgr: bone_capemgr bone_capemgr: slot #4: dtbo 'BB-ENABLE-PRU-00A0.dtbo' loaded; converting to live tree [ 65.875618] gpio-of-helper ocp:gpio_helper: ready [ 65.876327] gpiolib_of: of_get_named_gpiod_flags: parsed 'gpio' property of node '//fixedregulator@1[0]' - status (0) [ 65.876619] core: lz-codec-reg: no parameters [ 65.876713] fixed: reg-fixed-voltage fixedregulator@1: lz-codec-reg supplying 0uV [ 65.883284] pruss_uio 4a300000.pruss: pins are not configured from the driver [ 65.900080] bone_capemgr bone_capemgr: slot #4: dtbo 'BB-ENABLE-PRU-00A0.dtbo' loaded; overlay id #0 [ 65.946254] gpiolib_of: of_get_named_gpiod_flags: parsed 'gpio-reset' property of node '/ocp/i2c@4819c000/tlv320aic3104@0[0]' - status (0) [ 65.946317] core: tlv320aic3x-codec 2-0018: Looking up IOVDD-supply from device tree [ 65.946405] core: tlv320aic3x-codec 2-0018: Looking up DVDD-supply from device tree [ 65.946468] core: tlv320aic3x-codec 2-0018: Looking up AVDD-supply from device tree [ 65.946544] core: tlv320aic3x-codec 2-0018: Looking up DRVDD-supply from device tree [ 65.946606] snd_soc_core: tlv320aic3x-codec 2-0018: codec register 2-0018 [ 65.946640] snd_soc_core: tlv320aic3x-codec 2-0018: ASoC: dai register 2-0018 #1 [ 65.946655] snd_soc_core: tlv320aic3x-codec 2-0018: ASoC: Registered DAI 'tlv320aic3x-hifi' [ 65.946671] snd_soc_core: tlv320aic3x-codec 2-0018: ASoC: Registered codec 'tlv320aic3x-codec.2-0018' [ 65.956491] //sound/simple-audio-card,cpu: could not get #sound-dai-cells for /ocp/mcasp@48038000 [ 65.978759] snd_soc_core: davinci-mcasp 48038000.mcasp: ASoC: dai register 48038000.mcasp #1 [ 65.978795] snd_soc_core: davinci-mcasp 48038000.mcasp: ASoC: Registered DAI '48038000.mcasp' [ 65.978954] snd_soc_core: davinci-mcasp 48038000.mcasp: ASoC: Registered platform '48038000.mcasp' [ 66.012427] asoc-simple-card sound: parse error -22 [ 66.042609] asoc-simple-card: probe of sound failed with error -22 Note the bit about "#sound-dai-cells".

[alsa-devel] [PATCH v2 0/4] ASoC: Add support for DA7219 audio codec
by Adam Thomson 02 Oct '15

02 Oct '15

This patch set adds support for the DA7219 audio codec with built-in advanced accessory detection functionality. Patch set includes codec driver, associated DT bindings documentation and MAINTAINERS file updates to cover new bindings. This patch set is baselined against the v4.3-rc2 kernel version. Changes in v2: - Add SOC_DOUBLE_R_EXT support to ASoC core. - Use of upper-case naming for controls, where missing. - Use of Playback/Capture Digital naming for certain ADC/DAC controls. - CP mchange and vol_thresh DT bindings removed, now Kcontrols - Kcontrols and DAPM now locked as part of hptest work, and specific controls affected have had locking introduced. - Timeout for btn_det work when checking micbias status. - Added comments to describe reasoning for work use with hptest, btn_det. - Added comments to tonegen_freq_put/get to clarify endian conversion, and code now uses regmap_raw_read/write calls instead of bulk. - DT parsing code now prints dev_warn() for invalid settings. - SOC_VALUE_ENUM_SINGLE now used for hpf_mode handling, instead of customer get/put handlers. - DTMF key control now a SOC_ENUM to correctly describe supported keys, including non-numeric. - MIXIN_L_MIX_EN bit set as part of DAPM now (SUPPLY), rather than in probe. - Fix dai_sysclk() function to correctly check for no change, using clk_id as well as freq. - Error checking added for clk_set_rate() call. - Improved error checking for devm_clk_get() call. - Removed explicit use of device_may_wakeup() and enable/disable_irq_wake(). Now taken care of by I2C core so DT bindings updated accordingly to document this. - hptest work now uses cache to keep state, instead of reading registers individually. Cache is bypassed, then when test executed and complete, regcache_sync_region() used to restore settings to pre-test values. - Regulator consumer framework usage added, in particular to determine VDDIO level in use so device can be configured accordingly. DT documents updated to reflect this.
