2018-09-06ASoC: sgtl5000: avoid division by zero if lo_vag is zeroColin Ian King
In the case where lo_vag <= SGTL5000_LINE_OUT_GND_BASE, lo_vag is set to zero and later vol_quot is computed by dividing by lo_vag causing a division by zero error. Fix this by avoiding a zero division and set vol_quot to zero in this specific case so that the lowest setting for i is correctly set.

2017-06-14ASoC: sgtl5000: add avc supportRichard Leitner
The sgtl5000 features an automatic volume control block (AVC), which reduces loud signals and amplifies low level signals for easier listening. This patch adds support for this AVC block to the driver. Apart from the "AVC Switch" control which enables the block following controls for the configuration of AVC are added: + AVC Threshold Volume: threshold where audio is compressed when the measured level is above or expanded when below + AVC Max Gain Volume: maximum gain which can be applied when the measured audio level is below threshold + AVC Hard Limiter Switch: when enabled the signal is limited to the programmed threshold. + AVC Integrator Response: response time of the integrator The AVC block is enabled and configured using the DAP_AVC_CTRL and DAP_AVC_THRESHOLD registers.

Introduce the "lrclk-strength" property to allow LRCLK pad drive strength to be changed via device tree. When running a stress playback loop test on a mx6dl wandboard channel swap can be noticed on about 10% of the times. While debugging this issue I noticed that when probing the SGTL5000 LRCLK pin with the scope the swap did not happen. After removing the probe the swap started to happen again. After changing the LRCLK pad drive strength to the maximum value the issue is gone. Same fix works on a mx6dl Colibri board as well.

2016-06-15ASoC: sgtl5000: Fix regulator supportEric Nelson
Regulator support on SGTL5000 is broken because the VDDIO and VDDA and VDDD should be powered on before enabling MCLK as shown in Figure 4 of [1]. This requires moving control of the regulators from the codec block to the I2C block of the driver. The bulk of this patch consists of swapping the codec device with the i2c client. The new field num_supplies in struct sgtl5000_priv is used instead of ARRAY_SIZE(supplies) to handle the special case when the internal LDO is used instead of external VDDD. Note that ER1 in the SGTL5000 Errata document [2] suggests that all designs should use external VDDD. Since the internal LDO can only be enabled after I2C is available, there's no benefit in treating it as a regulator, so this patch removes the regulator structure surrounding it. Instead, a single block of code in sgtl5000_i2c_probe() performs the initialization sequence in section 2.2.1.1 of [3] and page 26 of [1].

According to the sgtl5000 datasheet the MCLK frequency range restriction of 8 to 27 MHz only applies when the PLL is used - synchronous SYS_MCLK input mode. When running the codec as slave, the master should generate MCLK in the range of 256*fs, 384*fs or 512*fs, which is called asynchronous SYS_MCLK input mode. In asynchronous SYS_MCLK we cannot have the 8 to 27 MHz check because if we want to play a 8KHz sample rate track, with a MCLK of 8k * 512 = 4.096MHz the current check would return -EINVAL, which is not correct. Remove the 8 to 27MHz frequency check, since this only applies to the synchronous SYS_MCLK input case.
