Subject: [RFC 4/4] ARM: dts: imx28: Add description for L2 switch on XEA board
Date: Thu, 26 Nov 2020 00:24:59 +0100 [thread overview]
Message-ID: <20201125232459.378-5-lukma@denx.de> (raw)
In-Reply-To: <20201125232459.378-1-lukma@denx.de>
The 'eth_switch' node is now used to enable support for L2 switch.
Moreover, a separate 'switch' node was introduced to keep the code more
clean.
