* i2c: parport: start using pr_fmtSudip Mukherjee2015-08-101-8/+8
| | | | | | | | | Start using pr_fmt and convert all remaining printk to use pr_* family of macros. Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org> [wsa: remove print on kzalloc failure] Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* i2c: parport: use dev_*Sudip Mukherjee2015-08-101-4/+5
| | | | | | | Now parport is using device model so use dev_* macros instead of printk. Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

* i2c-parport: define ports to connectSudip Mukherjee2015-06-011-0/+23
| | | | | | | | | | | As of now i2c-parport was connecting to all the available parallel ports. Lets limit that to maximum of 4 instances and at the same time define which instance connects to which parallel port.

* i2c-parport: i2c_parport_irq can be staticJean Delvare2012-10-051-1/+1
| | | | | | i2c_parport_irq is only called internally so it can be static. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-parport: Various cleanupsJean Delvare2011-05-241-15/+15
| | | | | | | | | | * Fix white space. * Rename labels to something meaningful. * Prefix defines with PORT_ to avoid collision with macros from <linux/parport.h>. * Add const markers where possible. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-parport: Fix adapter list handlingJean Delvare2011-05-011-13/+14
| | | | | | | | | | | Use a standard list with proper locking to handle the list of adapters. Thankfully it only matters on systems with more than one parallel port, which are very rare. Thanks to Lukasz Kapiec for reporting the problem to me. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: stable@kernel.org

| | | | | | parport_algo_data is a template so it can be marked const. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* 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.

* i2c-parport: Give powered devices some time to settleJean Delvare2010-03-021-1/+5

| | | | | | | | | | | | | | | | | | * Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>
* layered parport code uses parport->devDavid Brownell2007-05-081-0/+1
| | | | | | | | | | | | | | | | | | | Update some of the layered parport_driver code to use parport->dev: - i2c-parport (parent of i2c_adapter) - spi_butterfly (parent of spi_master, allowing cruft removal) - lp (creating class_device) - ppdev (parent of parportN device) - tipar (creating class_device) There are still drivers that should be updated, like some of the input drivers; but they won't be any worse off than they are today.

* i2c-parport: Fix a minor race on driver unloadJean Delvare2007-05-011-4/+8
| | | | | | | | | | When unloading the driver, we really want to unregister the i2c adapter before we power it off, rather than the other way around. Also speed up the bus a bit when we can sense SCL. The slaves will stretch the line as needed. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-parport: Optimize binary sizeJean Delvare2007-05-011-8/+5
| | | | | | | | Initialize the fields of the i2c_adapter structure individually, rather than copying a whole static template structure. This shaves off 474 bytes or 14% (on i386) from the binary size. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* [PATCH] i2c-parport: Make type parameter mandatoryMark M. Hoffman2006-04-141-2/+7
| | | | | | | | | | | | | | | | This patch forces the user to specify what type of adapter is present when loading i2c-parport or i2c-parport-light. If none is specified, the driver init simply fails - instead of assuming adapter type 0. This alleviates the sometimes lengthy boot time delays which can be caused by accidentally building one of these into a kernel along with several i2c slave drivers that have lengthy probe routines (e.g. hwmon drivers). Kconfig and documentation updated accordingly. Signed-off-by: Mark M.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+267
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
