* tty: move drivers/serial/ to drivers/tty/serial/Greg Kroah-Hartman2011-01-131-935/+0
| | | | | | | | | | | | | | | The serial drivers are really just tty drivers, so move them to drivers/tty/ to make things a bit neater overall. This is part of the tty/serial driver movement proceedure as proposed by Arnd Bergmann and approved by everyone involved a number of months ago.

| | | | | | | | | | | | | | | | | | | | | | | | | | The actual uart baud rate of devices vary between +/-2% of what is asked. The SPORT RX sample rate should be faster than double of the worst case.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* serial: fit blackfin uart over sport driver into common uart infrastructuresonic zhang2010-03-021-232/+469
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fit blackfin uart over sport driver into common uart inftrastructure. It is based on the early platform interfaces to get the platform data early when the console is initilized. 1. Enable sport uart driver to change uart baud, data bit, stop bit at runtime. Bind the index of uart device nodes to physical index of sports. 2. Move all platform data into arch specific board files. Register and probe platform device data in both early and normal stages. 3. Console is registered in sport uart driver as well. 4. Remove 500 us block waiting in sport tx stop code by putting a dummy data into tx fifo to make sure the sport tx stops when all bytes are shifted out except for the dummy data. 5. clean up a bit and fix up coding style.

* Blackfin SPORT UART: fix data misses while using transmit frame syncMichael Hennerich2009-06-111-1/+1
| | | | | | | | | | | | | | | | | | SPORT transmit frame sync (TFS) isn't used as an electrical signal during normal SPORT UART emulation. However, it is useful in EIA RS-485 emulation as RS-485 Transceiver Driver Enable DE strobe. This patch configures: TFS to be active high in order to drive an DE strobe of an eventually connected RS-485 Transceiver. Late frame sync mode (LATFS) gating the entire TX shift cycle.
