Subject: [PATCH RFC net-next 5/7] net: dsa: avoid DT validation for drivers which provide default config

From: "Russell King (Oracle)" <[email-masked]>
Date: Wed, 22 Mar 2023 12:00:16 +0000

When a DSA driver (e.g. mv88e6xxx) provides a default configuration,
avoid validating the DT description as missing elements will be
provided by the DSA driver.
