So back to my initial proposal, with a slight modification moving pwr_event first (e.g. as it is not a wakeup interrupt): qusb2-: - const: pwr_event - const: qusb2_phy - const: ss_phy_irq (optional) qusb2: - const: pwr_event - const: hs_phy_irq - const: qusb2_phy - const: ss_phy_irq (optional) femto-: - const: pwr_event - const: dp_hs_phy_irq - const: dm_hs_phy_irq - const: ss_phy_irq (optional) femto: - const: pwr_event - const: hs_phy_irq - const: dp_hs_phy_irq - const: dm_hs_phy_irq - const: ss_phy_irq (optional) That ss_phy_irq is optional would be expressed as minItems being one less than maxItems for each permutation.
I am fine with this except that "femto-" might not be required. I looked at https://lore.kernel.org/all/20231122191436.3146-1-quic_kriskura@xxxxxxxxxxx/ and I see that all of them have hs_phy_irq.
