Hi, These patches update the DT for the ZII VF610 boards. The first patch fixes complaints at boot about missing DMAs on rev C boards, particularly for the SPI interface. This is because edma1 is not enabled. This seems to be a regression from the 4.10 era. The second patch fixes an interrupt storm during boot on rev B boards, which causes boot to take 80+ seconds - this seems to be a long standing issue since the DT description was first added. The PTB28 pin is definitely GPIO 98, and GPIO 98 is definitely part of the gpio3 block, not the gpio2 block. Since GPIO 66 (which is the corresponding GPIO in gpio2) is low, and the IRQ trigger is level-low, this causes an interrupt storm. The last two patches add an explicit description of the PHYs that are actually connected to the switch - the 88e1545 is a quad PHY, and without describing the MDIO bus, DSA assumes that any PHYs it can discover are present for the switch. As only the first three PHYs are connected, this leads the 4th port to believe it is connected to the 4th PHY when the fixed-link definition is (eventually) removed. Head this off by providing the proper descriptions, and as we have them, also describe the interrupts for these PHYs. Note, however, that the interrupt description is not quite correct - the 88e1545 PHYs all share one interrupt line, and there is a register in the PHY which can be used to demux the interrupt to the specific PHY. However, in this description, we ignore the demux register, and just share the interrupt between the PHYs. That much is fine, but the pinmuxing becomes problematical - if we describe the same pinmux settings for each PHY for the interrupt line, the 2nd/3rd PHYs fail. This has no known solution.
