* net: asix: add AX88772B supportLucas Stach2012-09-26-12/+23
| | | | | | | | | | | | | | | | | | | | 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.

* net: asix: add read_mac functionLucas Stach2012-09-26-12/+35
| | | | | | | | | | | | | | Initial device MAC should be read while getting info about the device, so it's wrong to only read it in asix_init(). Add a dedicated function to read the initial MAC, which is also able to handle devices that have their initial MAC stored in EEPROM. Call this function inasix_eth_get_info().

* net: asix: add write_hwaddr functionLucas Stach2012-09-26-11/+52
| | | | | | | | | | | | | All ASIX chipsets aside from AX88172 are able to set the MAC address on the hardware level. Add a function to expose this ability. To differentiate between chip types we now carry flags as driver private data. Also while touching the asix_dongles array constify this.

* net: asix: split out basic reset functionLucas Stach2012-09-26-18/+26
| | | | | | | | | | | | The basic device reset ensures that the device is ready to service commands and does not need to get redone before each network operation. Split out the basic reset from asix_init() and instead call it from asix_eth_get_info(), so that it only gets called once.

| * ehci-hcd: Boost transfer speedBenoît Thébaudeau2012-09-01-29/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Discard the creepy cache flushing mechanisms in ehci-hcd.c and replace them with more straightforward flushing. In the new approach, the flushing takes place directly in ehci_submit_async() call instead of going through the QH list and flushing all members and buffers. This discards a lot of weird bit operations on the members of QH and qTD structures. NOTE: Certainly, this flushes even qTDs which are possibly unused in some transactions, though the overhead of the previous code was much higher than is the overhead of flushing two more cache lines (which most probably aren't even cached).

| | | | | | | | | | | | | | | | These two functions were called only from ehci_submit_async(), therefore dissolve them as part of ehci_submit_async() to get rid of all those static variables. Signed-off-by: Marek Vasut <marex@denx.de>

| | | | | | | | | | | | | | | | | | The reference manual of i.MX25 (nor i.MX31) does not define such register. This seems to access read only UH2_CAPLENGTH register (if CONFIG_MXC_USB_PORT is zero). Signed-off-by: Timo Ketola <timo@exertus.fi> Acked-by: Stefano Babic <sbabic@denx.de>
* | i.MX25: usb: Set PORTSCx registerTimo Ketola2012-05-15-2/+0
| | | | | | | | | | | | | | | | | | The USB controller in i.MX25 has a PORTSCx registers which should be set. In this regard it is similar to the controller in i.MX31. As this file is compiled only with i.MX25 and -31, #ifdef check can be removed. Signed-off-by: Timo Ketola <timo@exertus.fi> Acked-by: Stefano Babic <sbabic@denx.de>
