* input: key_matrix: fix header inclusionStephan Linz2012-09-02-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | On Microblaze with device tree support enabled we run into the error below. I'm not sure, but I think that all source code should include at least the common.h and just this fix the problem on Microblaz architecture. The error is: In file included from key_matrix.c:29: include/malloc.h:364: error: conflicting types for 'memset' include/linux/string.h:71: error: previous declaration of 'memset' was here include/malloc.h:365: error: conflicting types for 'memcpy' include/linux/string.h:74: error: previous declaration of 'memcpy' was here Signed-off-by: Stephan Linz <linz@li-pro.net> CC: Bernie Thompson <bhthompson@chromium.org> CC: Simon Glass <sjg@chromium.org> CC: Tom Warren <twarren@nvidia.com> CC: Michal Simek <monstr@monstr.eu> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Michal Simek <monstr@monstr.eu>

* rtc: pcf8563: Make century compatible with LinuxBenoît Thébaudeau2012-09-02-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This driver uses the century bit of this RTC in the opposite way Linux does. From Linux's rtc-pcf8563.c: /* * The meaning of MO_C bit varies by the chip type. * From PCF8563 datasheet: this bit is toggled when the years * register overflows from 99 to 00 * 0 indicates the century is 20xx * 1 indicates the century is 19xx * From RTC8564 datasheet: this bit indicates change of * century. When the year digit data overflows from 99 to 00, * this bit is set. By presetting it to 0 while still in the * 20th century, it will be set in year 2000, ... * There seems no reliable way to know how the system use this * bit. So let's do it heuristically, assuming we are live in * 1970...2069. */ As U-Boot's PCF8563 driver does not say it is supposed to support the RTC8564, make this driver compatible with Linux's by giving the opposite meaning to the century bit.

| * usb_stor_BBB_transport: Do not delay when not requiredBenoît Thébaudeau2012-09-01-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a 5-ms delay in usb_stor_BBB_transport, which occurs every 10 kiB of data for fragmented fatload usb, i.e. roughly 500 ms of delay per MiB. This adds up to quite a bit of delay if you're loading a large ramdisk. The purpose of this delay should be to debounce the 5-V/100-mA USB power up. This patch skips the delay if the device has already been queried as ready.

| * usb_storage: Remove EHCI constraintsBenoît Thébaudeau2012-09-01-18/+15

| | | | | | | | | | | | | | | | | | | | | | | | | | The commit 5dd95cf made the MSC driver EHCI-specific. This patch restores a basic support of non-EHCI HCDs, like before that commit. The fallback transfer size is certainly not optimal, but at least it should work like before.

| * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently patman assumes that there should be only one Signoff line and this is obviously incorrect: we often have to work with patches containing other people signoffs. Moreover, it's really desirable to preserve the comments between signoffs. So until some sophisticated signoff processing will be developed I suggest just don't mess with signoffs at all and treat them like plain text lines. The only drawback I've found so far is the case where you have a patch with someones else signoff but not yours and also have to patman tags under signoff line. In this case you will get extra empty line between signoffs. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>
