+
+maintainers:
+ - ChiYuan Huang <cy_huang@richtek.com>
+
+description: |
+ The RT9120 is a high efficiency, I2S-input, stereo audio power amplifier
+ delivering 2*20W into 8 Ohm BTL speaker loads. It supports the wide input
+ voltage range from 4.5V to 26.4V to meet the need on most common
+ applications like as TV, monitors. home entertainment, electronic music
+ equipment.
