Subject: [PATCH v2 0/2] Add support for Etek ET7304 Controller
Date: Thu, 19 Feb 2026 03:02:50 +0000	[thread overview]
Message-ID: <20260219-et7304-v2-0-b2e268494ae8@gmail.com> (raw)

The Etek ET7304 is a USB Type-C Port Controller with USB-PD used on
the Radxa Cubie A7Z.
According to the ET7304 datasheet [1] and the vendor BSP source code
provided by Radxa [2], this controller is functionally identical as
Richtek RT1715, with the only difference being the VID.

Add support for the ET7304 by registering its chip info in the driver.
Tested on Radxa Cubie A7Z.
