2020-08-17ASoC: da7219: Fix clock handling around codec level probeAdam Thomson1-0/+1
Previously the driver would use devm_* related functions at the codec level probe() to allocate clock resources for MCLK and the DAI clocks exposed by the device. This caused issues when registering clocks on a re-probe (no device level remove/prove involved) as the devm_* resources were never freed up so the clocks were still registered from the previous codec level probe(). This commit updates the clock handling for MCLK usage and DAI clock provision to fix this discrepancy and allow the codec level probe/remove functionality to operate as intended.

2019-03-21ASoC: da7219: Expose BCLK and WCLK control through CCFAdam Thomson1-3/+3
For the purposes of platforms which use the codec as DAI clock master for the CPU and other codec devices, there is the need to not only expose the clock gating of BCLK and WCLK but also the ability to set those rates without going through the ASoC APIs. To make this possible, the previous CCF implementation in the driver has been extended to separate BCLK and WCLK out. WCLK is the parent clock to BCLK, and is also the clock gate for both. BCLK in HW is a factor/multiplier of WCLK so derives from whatever SR is chosen for WCLK, hence the need to make it a child of WCLK for the purposes of CCF. Enabling/disabling either BCLK or WCLK will result in clocks being ungated/gated accordingly. To simplify matters, these clocks can only be configured if the codec is set as master, otherwise CCF control is disallowed.

2019-02-14ASoC: da7219: Add support for master mode BCLK rate adjustmentAdam Thomson1-0/+1
Previously the driver would default the BCLK periods per WCLK to 64, to cover all possible non-TDM scenarios when the codec was DAI clock master. However some devices require a lower BCLK rate to operate correctly so with this in mind, this commit updates the code to be more dynamic, with BCLK rate now based on SR and word length provided to hw_params().

2019-01-09ASoC: da7219: Add recalc_rate function to return DAI clock rateAdam Thomson1-0/+1
By making MCLK parent of DAI clocks, when querying the rate of the clock the rate returned is now given from the parent clock so gives the MCLK rate rather than 0 as previously returned. This is a bit misleading, and actually there's no major reason why we can't at least return the DAI WCLK rate, as set in HW, so that's what we now do.

2018-08-09ASoC: da7219: Add delays to capture path to remove DC offset noiseAdam Thomson1-2/+6
On some platforms it has been noted that a pop noise can be witnessed when capturing audio, mainly for first time after a headset jack has been inserted. This is due to a DC offset in the Mic PGA and so to avoid this delays are required when powering up the capture path. This commit rectifies the problem by adding delays post Mic PGA and post Mixin PGA. The post Mic PGA delay is determined based on Mic Bias voltage, and is only applied the first time after a headset jack is inserted.

2018-03-09ASoC: da7219: Add common clock usage for providing DAI clksAdam Thomson1-0/+9
There is a need to use DA7219 as DAI clock master for other codecs within a system, which means that the DAI clocks are required to remain, regardless of whether the codec is actually running playback/capture. To be able to expose control of the DAI clocking the common clock framework has been employed. The current implementation adds a simple clock gate for enabling and disabling the DAI clocks, with no rate control supported (this is still handled through standard hw_params() functions as before). If DT is enabled then the clock is added to the OF providers list, otherwise a clkdev lookup is used.

2017-06-19ASoC: da7219: Fix HP detection procedure for all MCLK frequenciesAdam Thomson1-1/+4
Currently when HP detection procedure runs for certain MCLK frequencies, when PLL is bypassed, the procedure will incorrectly report Lineout instead of Headphones due to timing incosistencies. To avoid this problem, the PLL is temporarily enabled (if currently bypassed and MCLK present) to provide consistent timings for the procedure, regardless of MCLK frequency.

2016-10-05ASoC: da7219: Improve pop/click performance for sensitive HPsAdam Thomson1-0/+5
Currently on some headsets slight pops can be heard during DAPM power-up/down. This can also be witnessed during the HP detect procedure. This patch addresses the issue by adjusting DAPM power sequencing slightly, the introduction of delays and use of minimum HP gain to avoid such noise artefacts.

2016-09-26ASoC: da7219: Disable AAD if codec is not a wake-up sourceAdam Thomson1-0/+1
Currently if AAD is enabled in the device, during system suspend the feature remains, regardless of whether the codec is a wake-up source or not. This means some additional power is being used which is unnecessary, and can causes issues with some platforms' IRQ handlers where state changes during system suspend aren't captured. This patch updates the driver to disable AAD during suspend, if we're not a wake-up source, and then re-enables this on resume.

2016-09-26ASoC: da7219: Reset codec gracefully, if still activeAdam Thomson1-0/+5
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.

2016-09-14ASoC: da7219: Support HP detect procedure when MCLK not presentAdam Thomson1-0/+2
Currently the driver code assumes that MCLK will be present during the procedure, or if it has control of MCLK then it can make sure it's enabled. Some platforms however do not provide MCLK to the driver in this way, and will not leave MCLK enabled when Codec is in STANDBY state. This patch adds support for the HP detect procedure when running from the device's internal oscillator, to ensure all platforms can make use of this feature correctly.
