[PATCH net-next v2 03/18] dt-bindings: net: cdns,macb: allow tsu_clk without tx_clk

Posted by Théo Lebrun 3 months, 1 week ago

Allow providing tsu_clk without a tx_clk as both are optional.

This is about relaxing unneeded constraints. It so happened that in the
past HW that needed a tsu_clk always needed a tx_clk.
