OMAP4: PMIC: Add support for twl6030 codec
In order to have TWL6030 CODEC driver as a platform driver, codec data
should be passed through twl_platform_data structure.
For twl6030 audio codec, the following data may be passed:
- audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high
transition powers codec up. Setting audpwron_gpio to a negative value
means that codec will use manual power sequence instead of automatic
sequence
- naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line
to low when an interrupt (codec ready, plug insertion/removal, etc) is
detected
However, codec driver can operate if any or none of them are passed.
