Re: [PATCH] phy: ti: gmii-sel: Allow parent to not be syscon node

Hi Andrew,

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.
Trying to understand the motive for this and if it is better to
introduce a "syscon = <&syscon_node>" property instead which
makes it fool proof for all cases.
