Yes that right, it is clock used to manage WoL during suspend. My problem it is may be to manage MCU and MPU family in same yaml file Because in MCU family only 3 clocks used (GMAC main clock, MAC TX clock and MAC RX clock) In MPU family it is same clocks + clock to manage WoL and clock to manage PHY without Cristal >> + - description: For MPU family, used for PHY without quartz > It would be cleaner to define the clock always present and use a > fixed-clock when you have an external quartz. You are right, I will define clocks always present and manage them in my driver (enable or disable it in function of phy mode, if with or without quartz in PHY etc..) So for MCU (st,stm32-dwmac) I need 3 clocks and for MPU (st,stm32mp1-dwmac) 5 clocks How to manage this in yaml ? 2 differents files ? >> + >> + clock-names: >> + minItems: 3 >> + maxItems: 5 >> + contains: >> + enum: >> + - stmmaceth >> + - mac-clk-tx >> + - mac-clk-rx >> + - ethstp >> + - eth-ck >> + >> +properties: >> + compatible: >> + oneOf: >> + - items: >> + - enum: >> + - st,stm32mp1-dwmac >> + - const: snps,dwmac-4.20a >> + - items: >> + - enum: >> + - st,stm32-dwmac >> + - const: snps,dwmac-4.10a >> + - items: >> + - enum: >> + - st,stm32-dwmac >> + - const: snps,dwmac-3.50a >> + >> + st,syscon: >> + allOf: >> + - $ref: "/schemas/types.yaml#/definitions/phandle-array" >> + description: >> + Should be phandle/offset pair.
