There is no risk to remove/rename these 2 properties, because it is specific board which is never deployed. With new properties (renaming clock (eth-ck) + st,eth_clk_sel and st,eth_ref_clk_sel, we are managed all kind of specific boards stm32mp1 So no risk of backward compatible. > >> +- clock-names: For MPU family "eth-ck" for PHY without quartz >> +- st,eth_clk_sel (boolean) : set this property in RGMII PHY when you do not want use 125Mhz >> +- st,eth_ref_clk_sel (boolean) : set this property in RMII mode when you have PHY without crystal 50MHz > > s/_/-/ > > 'sel' I assume is short for select, but the naming here and description > don't really tell me what I'm getting. > Ok, Rob, I will update with your recommendations > Rob >
