ARM: davinci: board-da850-evm: Add needed regulators for tlv320aic3106 codec
IOVDD: tps65070's dcdc2 AVDD and DRVDD: fixed regulator derived from 5V via TPS73701DCQ DVDD: fixed regulator derived from 5V via TPS73701DCQ This patch needed to be able to probe the audio codec. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>
