2012-10-15mx51: Fix USB PHY clocksBenoît Thébaudeau
The i.MX51 has a single USB PHY clock, while the i.MX53 has two. These 3 clocks have different clock gate control bit-fields. The existing code was correct only for i.MX53, so this patch fixes the i.MX51 use case.

Kill off ehci-core.h It was used to specify some static controller data. To support more than one controller being active at any time we have to carry the controller data ourselfes. Change the ehci interface accordingly. NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed to do the same thing as other platforms.

2012-09-26net: asix: add AX88772B supportLucas Stach
Add AX88772B ID together with two fixes needed to make this work. 1. The packet length check has to be adjusted, as all ASIX chips only use 11 bits to indicate the length. AX88772B uses the other bits to indicate unrelated things, which cause the check to fail. This fix is based on a fix for the Linux kernel by Marek Vasut. Linux upstream commit: bca0beb9363f8487ac902931a50eb00180a2d14a 2. AX88772B provides several bulk endpoints. Only the first IN/OUT endpoints work in the default configuration. So stop enumeration after we found them to avoid overwriting the endpoint config with a non-working one.

2012-09-01ehci-hcd: Boost transfer speedBenoît Thébaudeau
This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid software and transfer splitting overhead so as to make transfers as fast as possible. The only drawback is a call to memalign. However, this is fast compared to the transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the worst case for a transfer length of 65535 packets of 512 bytes. Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was very significant (several times faster), which is really appreciable when accessing large files.

2012-07-18ehci-hcd: fix external buffer cache handlingIlya Yanok
Buffer coming from upper layers should be cacheline aligned/padded to perform safe cache operations. For now we don't do bounce buffering so getting unaligned buffer is an upper layer error. We can't check if the buffer is properly padded with current interface so just assume it is (consider changing with in the future). The following changes are done: 1. Remove useless length alignment check. We get actual transfer length not the size of the underlying buffer so it's perfectly valid for it to be unaligned. 2. Move flush_dcache_range() out of while loop or it will flush too much. 3. Don't try to fix buffer address before calling invalidate: if it's unaligned it's an error anyway so let cache subsystem cry about that. 4. Fix end buffer address to be cacheline aligned assuming upper layer reserved enough space. This is potentially dangerous operation so upper layers should be careful about that.

2012-07-18ehci-hcd.c, musb_core, usb.h: Add USB_DMA_MINALIGN define for cache alignmentTom Rini
The USB spec says that 32 bytes is the minimum required alignment. However on some platforms we have a larger minimum requirement for cache coherency. In those cases, use that value rather than the USB spec minimum. We add a cpp check to <usb.h> to define USB_DMA_MINALIGN and make use of it in ehci-hcd.c and musb_core.h. We cannot use MAX() here as we are not allowed to have tests inside of align(...).
