+Kernel driver tps546d24
+=======================
+
+Supported chips:
+
+ * TI TPS546D24
+
+ Prefix: 'tps546d24'
+
+ Addresses scanned: -
+
+ Datasheet: https://www.ti.com/lit/gpn/tps546d24
+
+Author: Duke Du <dukedu83@gmail.com>
+
+
+Description
+-----------
+
+The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable
+of high frequency operation and 40-A current output from a 7-mm x 5-mm
+package.
+
+Two, three, and four TPS546D24A devices can be interconnected
+to provide up to 160 A on a single output. The device has an option to
+overdrive the internal 5-V LDO with an external 5-V supply via the VDD5
+pin to improve efficiency and reduce power dissipation of the converter.
+
+
+Platform data support
+---------------------
+
+The driver supports standard PMBus driver platform data.
