Bug#1032671: linux: Enable USB_XHCI_PCI_RENESAS on arm64

[Cyril Brulebois]

Source: linux
Severity: normal
Tags: patch

Hi,

The µPD720201 and µPD720202 controllers from Renesas are USB 3.0 Host
Controllers making it possible to get several USB 3 lines from a single
PCIe slot.

I'm suggesting enabling the relevant module on arm64 as having that
module enabled is quite useful on devices like Raspberry Pi CM4, but
that might be useful on other architectures. Seeing how arm64 has the
most USB_HCI_* modules enabled, that's why I'm sticking to this
particular architecture in my initial patch.

Please note that these controllers require a firmware to operate; it can
be stored on an EEPROM next to the controller, or loaded directly from
/lib/firmware/renesas_usb_fw.mem

More information about the firmware:

Repository containing the firmware (UPDATE.mem):

Thanks for considering!

Cheers,

Did you forget to enclose the patch?
Do you still have it?

Yes, chicken and egg problem, I wanted to open a bug report first to
reference it in the commit / branch / merge request, but failed to
update the bug report afterwards; thanks for doing so, Diederik.
