const char * const [] is the preferred type for static string arrays since this states explicitly that the individual entries are not going to be changed.

2016-11-14ASoC: lpass-platform: fix uninitialized variableLinus Torvalds
In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data usage") the stream specific information initialization was broken, with the dma channel information not being initialized if there was no alloc_dma_channel() helper function. Before that, the DMA channel number was implicitly initialized to zero because the backing store was allocated with devm_kzalloc(). When the init code was rewritten, that implicit initialization was lost, and gcc rightfully complains about an uninitialized variable being used.

2016-11-13ASoC: Intel: detect audio routing with CHAN packagePierre-Louis Bossart
Baytrail-CR devices usually expose information in the DSDT which can be used to auto-detect AIF1/AIF2 connections. The CHAN package contains two integers, the first one describes the AIF number (1: AIF1, 2: AIF2) and the second the MCLK value (ignored in this patch) For example the following information is found in Lenovo 100s: Device (RTEK) { [...] Name (CHAN, Package (0x02) { One, 0x017D7840 }) While on Asus T100TAF the package values are: Name (CHAN, Package (0x02) { 0x02, 0x017D7840 }) This patch relies on the new common routine to extract a package exposed by a device indexed with the HID value. The CHAN package contents are queried from the machine driver and stored in a structure. If this auto-detection fails (missing or bad package in the BIOS), the routing falls back to SSP0-AIF2. Note that quirks may still be needed to support mono speakers or microphone, but this should reduce the number of issues with Baytrail significantly.

This patch handles publishing acknowledged controls through ALSA. These controls allow user-side to send events to the firmware and wait for the firmware to acknowledge it. Note that although acked controls only operate in the direction host->firmware, and therefore they are write-only as seen from user- side code, we have to make them readable to account for all the code out there that assumes that ALSA controls are always readable (amixer for example.)

Both of which were removed in commit 28c8331d386a ("ARM: S5PV210: Remove support for board files") over two years ago. The driver has been unselectable ever since.

2016-11-11ASoC: nau8825: FLL parameters finetuneJohn Hsu
The driver fine-tune some parameters to improve FLL performance. Those items have description as follow. (1)ICTRL_LATCH: FLL DSP speed capability control When FLL running at high frequency with long decimal number, DSP needs to operate at high speed. FLL DSP can optimize between performance and power consumption by ICTRL_LATCH.(111 has highest power consumption.) The default setting can be used to reduce power. (2)CUTOFF500: loop filter cutoff frequency at 500Khz It will give the best FLL performance but highest power consumption to enable the cutoff frequency. FLL Loop Filter enable to reduce FLL output noise, especially,(DCO frequency)/(FLL input reference frequency) is not a integer. (3)GAIN_ERR: FLL gain error correction threshold setting The threshold is comparison between DCO and target frequency. The value 1111 has the most sensitive threshold, that is, 1111 can have the most accurate DCO to target frequency. However, the gain error setting conditionally and inversely depends on FLL input reference clock rate. Higher FLL reference input frequency can only set lower gain error, such as 0000 for input reference from MCLK=12.288Mhz. On the other side, if FLL reference input is from Frame Sync, 48KHz, higher error gain can apply such as 1111.

2016-11-11ASoC: nau8825: AD/DA over sampling rate configurationJohn Hsu
Over Sampling Rate (OSR) is defined as CLK_ADC frequency divided by the audio sample rate (Fs). OSR = CLK_ADC / FS The available OSRs are 32, 64, 128 or 256. Note that the OSR and Fs values must be selected such that the maximum frequency of CLK_ADC is less than 6.144 MHz. It is recommended to match the relationship between OSR and clock SRC according to following Table. ADC_RATE: 00(OSR=32) | CLK_ADC_SRC: 11(CODEC 1/8) ADC_RATE: 01(OSR=64) | CLK_ADC_SRC: 10(CODEC1/4) ADC_RATE: 10(OSR=128) | CLK_ADC_SRC: 01(CODEC 1/2) ADC_RATE: 11(OSR=256) | CLK_ADC_SRC: 00(CODEC CLK) The over sampling rate about DAC follows the same rule with ADCs. The driver changes the OSR to 64 value when initiation for better FLL performance and applies the dynamic SRC change by different OSR.

2016-11-11ASoC: nau8825: Disable short Frame Sync detection logicJohn Hsu
If the short Frame Sync detection logic enabled, the logic will check the short frame sync threshold. If frame sync is less than the setting; for example, frame sync less than 252 MCLK, the short frame sync signal is flagged, digital filter temporary mute and skip that data. If the system was intended for sampling rate change which could create temporary short frame sync and not enough MIPS to run the digital filter. But the situation doesn't happen in ALSA architecure. Thus the Frame Sync is always stable, then no require to do the detection. Therefore, the dirver disables the function for better performance.

The call to arizona_init_notifiers was only added for CODECs that are generating voice trigger events, however, this is somewhat annoying for machine drivers that might be used with multiple CODECs as they need to conditionally register for the notifier, depending on the CODEC being attached.
