0ea23660c7 ASoC: cs42l42: Wait at least 150us after writing SCLK_PRESENT 
There must be a delay of at least 150us after writing SCLK_PRESENT
before issuing another I2C write.

This is done using struct reg_sequence because it can specify a delay
after the write and the whole sequence is written atomically.

2cdba9b045 ASoC: cs42l42: Use bclk from hw_params if set_sysclk was not called 
Add support for reading the source clock from snd_soc_params_to_bclk
so the machine driver is not required to call cs42l42_set_sysclk

Report the Jack events to the user space through ALSA.
Also moves request_threaded_irq() to component_probe so it don't get
interrupts before the initialization the struct snd_soc_jack.

19325cfea0 ASoC: cs42l42: Always wait at least 3ms after reset 
This delay is part of the power-up sequence defined in the datasheet.
A runtime_resume is a power-up so must also include the delay.
