* USB: Drop cache flush bloat in EHCI-HCDMarek Vasut2012-05-20-100/+27
| | | | | | | | | | | | | | | 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).

* USB: Drop ehci_alloc/ehci_free in ehci-hcdMarek Vasut2012-05-20-91/+32
| | | | | | | | 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>
* lin_gadget: use common linux/compat.hMike Frysinger2012-04-30-3/+4
| | | | | | | | | | | | | | | | Merge our duplicate definitions with the common header. Also fix drivers/usb/gadget/s3c_udc_otg_xfer_dma.c to use min() instead of min_t() since we remove the latter from compat.h. Additionally use memalign() directly as the lin_gadget specific kmalloc() macro is removed from lin_gadget_compat.h by this patch.

* ehci-omap: fix for enabling the correct usb portJeroen Hofstee2012-04-21-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is just a patch for the problem reported here: http://lists.denx.de/pipermail/u-boot/2012-February/117580.html originally reported by Igor. "Looks like this is copy paste error from my side,(for port2/3 it should have been bypass for port2/3 rather its port1 set in bypass mode)" I only submit the patch since it is missing in 2012.04-rc3 while the twister board depends on it. Maybe it is already somewhere in the reposistory, but I cannot find it. note: the twister boards still needs an additional `usb reset`, don't know why.

| * Enable high speed support for USB device framework and usbttyVipin KUMAR2012-03-28-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support. Along with that specific peripheral drivers also need to define a function to let the framework know that the enumeration has happened at high speed. This function prototype is "int is_usbd_high_speed(void)" Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com>

| | | | | | | | | | | | | | | | | | | | | | In 9792987721c7980453fe6447c3fa6593b44f8458 Stefan describes a usecase where the previous behavior of leaving wMaxPacketSize be unaligned caused fatal problems. The initial fix for this problem was incomplete however as it showed another cases of non-aligned access that previously worked implicitly. This switches to making sure that all access of wMaxPacketSize are done via (get|put)_unaligned. In order to maintain a level of readability to the code in some cases we now use a variable for the value of wMaxPacketSize and in others, a macro.
