Subject: [PATCH 06/10] usb: host: dwc3-sti-glue: Migrate to use ofnode API
Date: Wed, 19 Feb 2020 09:54:43 +0800 [thread overview]
Message-ID: <20200219015447.19392-7-kever.yang@rock-chips.com> (raw)
In-Reply-To: <20200219015447.19392-1-kever.yang@rock-chips.com>
Use ofnode_ instead of fdt_ or fdtdec_ APIs so that the driver can support
live DT.
