This patch makes the codec playback rails (headset and speaker) depend on actual pins they control. This enables better power management of the codec 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:

If a widget has been force enabled then not only do we need to keep the widget itself enabled, we also need to keep any supplies the widget requires enabled. The user could force all the individual widgets on but this requires too much knowledge of device internals. Signed-off-by:

It is safe to use sleeping gpio in snd_soc_jack_gpio_detect as it is not called from interrupt context. This avoids WARN_ON from __gpio_get_value if sleeping gpio is registered for jack. Signed-off-by:

This makes no real difference compared to the write sequencer sequence that was previously used but can run without a clock being provided. Also remove the write sequencer support code as this was the last use of it. Signed-off-by:

The write sequencer sequencer sequence takes longer than is desirable as it brings up a full playback path which is not required at this point. Open coding the sequence cuts the startup time by two thirds. Signed-off-by:

Content of the CX20442's snd_soc_codec_driver.reg_cache_default pointed area, introduced with my recent NULL pointer dereferece fix (commit f019ee5f), occured wrong after further testing, more thorough than just booting successfully. There are two problems with it: 1) It should read (1 << CX20442_TELOUT) | (1 << CX20442_MIC), not CX20442_TELOUT | CX20442_MIC. 2) While correctly matching actual codec hardware state on boot when fixed per 1), a few more code modifications would still be required to reflect that state not only into register cache, but also force them into DAPM pins state, otherwise an inconsitency occures which may prevent further codec state changes from being applied correctly. As a result, the phone stops ringing after reboot, until someone picks up the handset for the first time. Revert that reg_cache_default content to a working, previous de facto default value of 0, in hope this change can still be accepted as an rc cycle fix.

ASoC generally uses the register defaults for everything, but in some cases the hardware will default to enabling some of the DAPM widgets (clocks for example). Ensure that DAPM knows about the actual widget state at initialisation by reading the enable bits after instantiating the widgets so they don't get left enabled needlessly. Signed-off-by:

The wm8753 codec supports switching between different DAI modes. The current drivers tries to implement this by changing the DAI driver at runtime. But to properly work this would require support from the ASoC core. So this patch takes a different approch on how the DAI mode switching is implemented. The only difference, from a driver point of view, between the different DAI modes is how to program the DAI format to the hardware. So what this patch is, it stores the current format for each DAI in the drivers private struct and when the DAI mode is changed the format gets simply reprogrammed according to the new DAI mode. Futhermore this patch restricts the changing of the DAI format to when the codec is inactive. Signed-off-by:
