Initialize EHCI controllers on AST2400 and AST2500 using the existing
TYPE_PLATFORM_EHCI. After this change, booting ast2500-evb into Linux
successfully instantiates a USB interface.

Cool. Have you tried to plug any devices ?

This looks good. Could you add the AST2600 also ?

The devicetree include file for ast2600 doesn't even have an entry for it. I could cook something up, but that would not reflect real hardware. Thanks, Guenter

FYI, there are patches on the linux-aspeed list to enable USB: https://patchwork.ozlabs.org/project/linux-aspeed/list/?series=156260 They have not yet been merged into the kernel, but I will merge the device tree changes once -rc1 is out. (I don't see any patches that enable the driver though, so I'll have to follow that up with Tao) Cheers, Joel

With the above series, and after enabling ehci1 for ast2600-evb and adding the necessary code to qemu, I get ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver ehci-platform: EHCI generic platform driver ehci-platform 1e6a3000.usb: EHCI Host Controller ehci-platform 1e6a3000.usb: new USB bus registered, assigned bus number 1 ehci-platform 1e6a3000.usb: irq 25, io mem 0x1e6a3000 ehci-platform 1e6a3000.usb: USB 2.0 started, EHCI 1.00 usb usb1: Manufacturer: Linux 5.5.0-09825-ga0802f2d0ef5-dirty ehci_hcd and I can mount a USB drive. Is that good enough for a follow-up patch, or should I wait until the code finds its way into the Linux kernel ? Thanks, Guenter

I suppose we could activate EHCI on the ast2600 evb. Anyhow, let's move on. Reviewed-by: Cédric Le Goater <clg@kaod.org> Thanks, C.
