Subject: [PATCH 5.5 11/65] net: dsa: mt7530: move mt7623 settings out off the mt7530
From: "René van Dorst" <opensource@...rst.com>
[ Upstream commit 84d2f7b708c374a15a2abe092a74e0e47d018286 ]
Moving mt7623 logic out off mt7530, is required to make hardware setting
consistent after we introduce phylink to mtk driver.
Fixes: ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK API")
