Hi Samuel, * Roger Quadros [off-list ref] [121210 02:23]:
Instead of using cpu_is_omap..() macros in the device driver we rely on information provided in the platform data. The only information we need is whether the USB Host module has a single ULPI bypass control bit for all ports or individual bypass control bits for each port. OMAP3 REV2.1 and earlier have the former.
I'd like to apply this patch as a fix so I can finally nuke plat/cpu.h for omaps by -rc1 before more drivers start using it again. That is assuming nobody else is planning on merging this series for v3.8 presumably. Want to ack this one? Regards, Tony
