+Kernel driver ina3221
+=====================
+
+Supported chips:
+
+  * Texas Instruments INA3221
+
+    Prefix: 'ina3221'
+
+    Addresses: I2C 0x40 - 0x43
+
+    Datasheet: Publicly available at the Texas Instruments website

+Description
+-----------
+
+The Texas Instruments INA3221 monitors voltage, current, and power on the high
+side of up to three D.C. power supplies. The INA3221 monitors both shunt drop
+and supply voltage, with programmable conversion times and averaging, current
+and power are calculated host-side from these.
