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@xxxxxxxxxxx> --- Documentation/devicetree/bindings/net/stm32-dwmac.yaml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Documentation/devicetree/bindings/net/stm32-dwmac.yaml b/Documentation/devicetree/bindings/net/stm32-dwmac.yaml index ca976281bfc22..54fda8b052abc 100644 --- a/Documentation/devicetree/bindings/net/stm32-dwmac.yaml +++ b/Documentation/devicetree/bindings/net/stm32-dwmac.yaml @@ -78,12 +78,21 @@ properties: encompases the glue register, the offset of the control register and the mask to set bitfield in control register + st,ext-phyclk: + description: + set this property in RMII mode when you have PHY without crystal 50MHz and want to + select RCC clock instead of ETH_REF_CLK. or in RGMII mode when you want to select + RCC clock instead of ETH_CLK125. + type: boolean + st,eth-clk-sel: + deprecated: true description: set this property in RGMII PHY when you want to select RCC clock instead of ETH_CLK125. type: boolean st,eth-ref-clk-sel: + deprecated: true description: set this property in RMII mode when you have PHY without crystal 50MHz and want to select RCC clock instead of ETH_REF_CLK. -- 2.25.1
