Add property st,ext-phyclk to manage cases when PHY have no cristal/quartz This property can be used with RMII phy without cristal 50Mhz and when we want to select RCC clock instead of ETH_REF_CLK Can be used also with RGMII phy with no cristal and we select RCC clock instead of ETH_CLK125 This new property replace st,eth-clk-sel and st,eth-ref-clk-sel Signed-off-by: Christophe Roullier <christophe.roullier@foss.st.com> --- Documentation/devicetree/bindings/net/stm32-dwmac.yaml | 9 +++++++++ 1 file changed, 9 insertions(+)
