2016-12-06ASoC: nau8825: disable sinc filter for high THD of ADCJohn Hsu
This bit will enable 4th order SINC filter. =1, filter will enable; but it consumes higher power. =0, the sinc filter is disable, and it should always keep 0 value to get high THD. Therefor, disable the filter when codec initiation for better performance when recording. Signed-off-by: John Hsu <KCHSU0@nuvoton.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-11-30ASoC: nau8825: lock longer to avoid playback pop upon resumeJohn Hsu
There is an issue about pop noise in NAU88L25 as follows. Issue 54078: Chell_headphone pop back from S3 (1)Play directly to hw, bypassing CRAS: sox -b 16 -n -t alsa hw:0,0 synth sine 200 sine 200 (2)Close lid or powerd_dbus_suspend, then press a key to resume. (3)no audio after resume (4)Audio will be back after close then reopen the pcm device. After verification, we find one defect is that semaphone lock is not long enough and expired. In this situation, the playback comes back early but pauses a while to wait for the crosstalk detection done. But the detection spends too much time and lock time is up. Therefore, the playback and jack detection sequence interfere to each other. That breaks sequence and makes noise. The driver extends the lock time for the issue.

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.

2016-10-11kthread: kthread worker API cleanupPetr Mladek
A good practice is to prefix the names of functions by the name of the subsystem. The kthread worker API is a mix of classic kthreads and workqueues. Each worker has a dedicated kthread. It runs a generic function that process queued works. It is implemented as part of the kthread subsystem. This patch renames the existing kthread worker API to use the corresponding name from the workqueues API prefixed by kthread_: __init_kthread_worker() -> __kthread_init_worker() init_kthread_worker() -> kthread_init_worker() init_kthread_work() -> kthread_init_work() insert_kthread_work() -> kthread_insert_work() queue_kthread_work() -> kthread_queue_work() flush_kthread_work() -> kthread_flush_work() flush_kthread_worker() -> kthread_flush_worker() Note that the names of DEFINE_KTHREAD_WORK*() macros stay as they are. It is common that the "DEFINE_" prefix has precedence over the subsystem names. Note that INIT() macros and init() functions use different naming scheme. There is no good solution. There are several reasons for this solution: + "init" in the function names stands for the verb "initialize" aka "initialize worker". While "INIT" in the macro names stands for the noun "INITIALIZER" aka "worker initializer". + INIT() macros are used only in DEFINE() macros + init() functions are used close to the other kthread() functions. It looks much better if all the functions use the same scheme. + There will be also kthread_destroy_worker() that will be used close to kthread_cancel_work(). It is related to the init() function. Again it looks better if all functions use the same naming scheme. + there are several precedents for such init() function names, e.g. amd_iommu_init_device(), free_area_init_node(), jump_label_init_type(), regmap_init_mmio_clk(), + It is not an argument but it was inconsistent even before.

tlv320dac31xx is a subset of tlv320aic31xx: - it does not have MIC inputs and ADC, thus capture is not supported, - it has analog inputs AIN1/AIN2 that can be mixed into output. Although tlv320dac31xx does work with tlv320aic31xx driver, this setup does register non-existent widgets and non-existent capture stream. Thus userspace lists non-existent objects in user interfaces, an can access these, causing operations with device registers that are declared as "reserved" in tlv320dac31xx datasheet. This patch fixes this situation by separating controls/widgets/routes into common, aic31xx-specific, and dac31xx-specific parts. Only parts that match actual hardware (as declared in "compatible" device tree property) are registered.

2016-09-26ASoC: da7219: Reset codec gracefully, if still activeAdam Thomson
Currently the reset code in i2c_probe only resets the AAD part of the device and not the entire codec. This patch updates the driver to resolve this and ensures that if the codec is still active from a previous boot then the audio paths are powered down prior to reset.
