We unconditionally require SYSCLK since while only microphone detection specifically requires SYSCLK any actual use case would enable it via some other means but microphone detection may have nothing active other than the bias itself.

With generic AC97 ASoC glue driver (codec/ac97.c), we get following warning when the device is registered (slightly stripped the backtrace): kobject (c5a863e8): tried to init an initialized object, something is seriously wrong. [<c00254fc>] (unwind_backtrace+0x0/0xec) [<c014fad0>] (kobject_init+0x38/0x70) [<c0171e94>] (device_initialize+0x20/0x70) [<c017267c>] (device_register+0xc/0x18) [<bf20db70>] (snd_soc_instantiate_cards+0x924/0xacc [snd_soc_core]) [<bf20e0d0>] (snd_soc_register_platform+0x16c/0x198 [snd_soc_core]) [<c0175304>] (platform_drv_probe+0x18/0x1c) [<c0174454>] (driver_probe_device+0xb0/0x16c) [<c017456c>] (__driver_attach+0x5c/0x7c) [<c0173cec>] (bus_for_each_dev+0x48/0x78) [<c0173600>] (bus_add_driver+0x98/0x214) [<c0174834>] (driver_register+0xa4/0x130) [<c001f410>] (do_one_initcall+0xd0/0x1a4) [<c0062ddc>] (sys_init_module+0x12b0/0x1454) This happens because the generic AC97 glue driver creates its codec->ac97 via calling snd_ac97_mixer(). snd_ac97_mixer() provides own version of snd_device.register which handles the device registration when snd_card_register() is called. To avoid registering the AC97 device twice, we add a new flag to the snd_soc_codec: ac97_created which tells whether the AC97 device was created by SoC subsystem.

It is not needed since snd_ac97_mixer() will create a new ac97 object for us. Removing the call also fixes a memory leak since codec->ac97 is set to NULL at the beginning of snd_ac97_mixer().

Dramatically reduce the code size for the WM8962 register defaults table by switching to explicitly initialise only defined registers, relying on static defaulting to zero for the overwelming bulk of the register map. Similar treatement for the register access table will come later and will produce a similarly dramatic code size shrink.

Rather than block the workqueue by sleeping to do the debounce use delayed work to implement the debounce time. This should also means that we extend the debounce time on each new bounce, potentially allowing shorter debounce times for clean insertions.

Since only 4 mainline ASoC codecs support the trigger callback, we cannot rely upon them stopping the frame clock if they are master and must assume it is running even if the sound is paused. Thus we cannot start the ASP until the trigger method.

GPIO2 and GPIO3 on the WM8962 are MFPs and need to be put into GPIO mode before the GPIO block can be used to control them. We're already doing this when used via gpiolib, factor out the code for use when setting static configurations via platform data as well.

Allow microphone detection on WM8962 to be performed using the interrupt signal, allowing the detection of both microphone presence and button presses with a signal singal from the CODEC to CPU. Currently a 250ms debounce time is applied to both short circuit and presence detection, this has not been optimised.

While it is a generic serial port in practice the i.MX SSI is only supported in Linux as an audio port (the i.MX has dedicated SPI controllers and so on). This means we don't need to disambiguate against other uses of the hardware and so can drop the -dai suffix from the driver name which fixes merge issues with the i.MX tree in -next.
