[PATCH 0/2] Small fixes for ASMedia host controllers

[Forest Crossman]

The first patch just defines some host controller device IDs to make the
code a bit easier to read (since the controller part number is not
always the same as the DID) and to prepare for the next patch.

The second patch defines a new device ID for the ASM1142 and enables the
XHCI_NO_64BIT_SUPPORT quirk for that device, since it has the same
problem with truncating the higher bits as the ASM2142/ASM3142.

Ah, whoops, I'm very sorry about that! Should I send a v2 of just this
patch? Or would it be better to send the whole series again?


Thanks,

Whole series is always easier to handle.

[PATCH 2/2] usb: xhci: Fix ASMedia ASM1142 DMA addressing

[Forest Crossman]

I've confirmed that the ASMedia ASM1142 has the same problem as the
ASM2142/ASM3142, in that it too reports that it supports 64-bit DMA
addresses when in fact it does not. As with the ASM2142/ASM3142, this
can cause problems on systems where the upper bits matter, and adding
the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.

[PATCH v2 1/2] usb: xhci: define IDs for various ASMedia host controllers

[Forest Crossman]

Not all ASMedia host controllers have a device ID that matches its part
number. #define some of these IDs to make it clearer at a glance which
chips require what quirks.

   You shouldn't have un-indented it, blends with the branch below.
   The 80-column line length limit is history now. :-)
