The utilities will be required by every machine driver. Including the utility object directly into every machine driver causes a build failure if the modules are actually built into the kernel, since each will define the symbols exported by the utility file. Solve this by moving the utility object into a separate module. Signed-off-by:

Sometimes the name of the control switch of a dapm route contains spaces which makes it impossible to distinguish it from the source widget. Add quotes around the names of the widgets to makes these parsable. Signed-off-by:

The default WM8958 jack detection handler implements a full set of buttons and also support for video detection. Support for multi-button jacks is fairly system specific and will usually require some tuning for headsets so simplify the implementation to only report a simple short to ground button, leaving multi-button headsets to be handled by system specific code.

The WM8958 has a different microphone bias architecture to WM8994 so needs different configuration to WM8994. Support this in platform data. Signed-off-by:

Allow direct routing of the WM8958 microphone detection signal to a GPIO to be used, saving the need to demux the interrupt. Signed-off-by:

As bias level changes can be quite time consuming and the bias changes for multiple devices aren't strongly tied to each other (if anything it can be advantageous to bring different devices up together) we can improve the state transition time for multi-component systems by running the bias level changes for all the devices in parallel. This is very simple to achieve using the kernel async functionality so use that to schedule the work. This should have no practical effect for the overwhelming majority of systems which have a single DAPM context - we'll bounce into another thread to do the bias level change but otherwise everything will happen in exactly the same order as it did before.

The microphone detection functionality requires a clock to work. In any non-detection case where the MICBIAS is enabled CLK_SYS will be needed anyway so there is no negative impact on power consumption. Signed-off-by:

Pulseaudio doesnt work with current driver and it was root caused to absense of hw_params function and malloc_pages in it. This patch adds this and allows pa to work fine with these drivers Signed-off-by:

The WM8903 interrupts are clear on read so if the WM8903 detection is enabled from platform data when the IRQ is in use (rather than using a direct signal from a GPIO) status may be lost during startup. Help users spot this misconfiguration by adding a WARN_ON(). Signed-off-by:

Harmony has both an external mic (a regular mic jack) and an internal mic (a 0.1" two-pin header on the board). The external mic is connected to the WM8903's IN1L pin, and is supported by the current driver. The internal mic is connected to the WM8903's IN1R pin, and is not supported by the current driver. It appears that no Harmony systems were shipped with any internal mic connected; users were expected to provide their own. This makes the internal mic connection less interesting. The WM8903's Mic Bias signal is used for both of these mics. For each mic, a GPIO drives a transistor which gates whether the mic bias signal is actively connected to that mic, or isolated from it. The dual use of the mic bias for both mics makes a general-purpose complete implementation of mic detection using the mic bias complex. So, for simplicity, the internal mic is currently ignored by the driver. This patch configures the relevant GPIOs to enable the mic bias connection to the external mic, and disable the mic bias connection to the internal mic. Note that in practice, this is the default state if these GPIOs aren't configured. Signed-off-by:
