Subject: [PATCH 1/3] usb: dwc3: of-simple: Add compatible for rk3328
Date: Sun, 16 Aug 2020 19:16:50 +0200 (CEST) [thread overview]
Message-ID: <MEsGWB_--3-2@tutanota.com> (raw)
Add a compatible to be hooked into by the Rockchip rk3328 device tree.
The rk3399 compatible cannot be reused because the rk3328 SoCs may
require a specialized driver in the future, and old device trees must
remain commpatible with newer kernels.
