Subject: brcm63xx: fix ohci frame number offset
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e83c1ec61ce99e73e5b6261668563cf018ea4ad2;p=openwrt%2Fstaging%2Fynezz.git

brcm63xx: fix ohci frame number offset

BCM63XX's ohci controller does not need the frame number shift, but that
was guarded with a PPC symbol. Fix this by making the no-fix generally
available.

This is a regression from the previous conversion to ohci platform driver.

+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.
