Subject: [PATCH] phy: ti: gmii-sel: Allow parent to not be syscon node
Date:   Mon, 15 May 2023 14:59:22 -0500

If the parent node is not a syscon type, then fallback and check
if we can get a regmap from our own node. This no longer forces
us to make the parent of this node a syscon node when that might
not be appropriate.
