Subject: [PATCH] USB: OHCI: allow other arches to use the BE frame number
|
|
|
|
|
quirk
|
|
|
|
|
|
|
|
|
|
Intead of guarding it with a certain PPC SoC and expanding the list
|
|
|
|
|
for each SoC requiring it, just guard it with USB_OHCI_BIG_ENDIAN_DESC.
|
|
|
|
|
|
|
|
|
|
This makes it less suprising that passing no_big_frame_no = 1 for the
|
|
|
|
|
platform data does not do what expected (or
|
|
|
|
|
|
|
|
|
|
Checking it for all big endian descriptor setups should not impact
|
|
|
|
|
performance much as USB1.1 is rather slow anyway.
