The Spreadtrum SC9860 platform has one SC2731 PMIC, and the SC2731 PMIC integrates all mobile handset power management, audio codec, battery management and user interface support function in a single chip. This patch adds the SC2731 dts file, as well as adding the RTC and regulator device node for this PMIC.
