ASoC: add DT bindings for cs4270 Signed-off-by: Daniel Mack <zonque@gmail.com> Acked-by: Timur Tabi <timur@freescale.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

CS4270 audio CODEC
The driver for this device currently only supports I2C.
Required properties:
- compatible : "cirrus,cs4270"
- reg : the I2C address of the device for I2C
ASoC: Add reset-gpio DT property to cs4270 driver In the process of moving over from static board files to the device tree, reset pins of peripheral reset pins should be handled by their corresponding drivers. Add a reset-gpio DT property to the cs4270 driver, and de-assert it before probing the chip. The logic could be augmented some day to re-assert it when codec is put to suspend.

Optional properties:
- reset-gpio : a GPIO spec for the reset pin. If specified, it will be
deasserted before communication to the codec starts.
