* [media] tda829x: fix regression in probe functionsJarod Wilson2011-03-021-7/+7
| | | | | | | | | | | | | | | | | | | | | In commit 567aba0b7997dad5fe3fb4aeb174ee9018df8c5b, the probe address for tda8290_probe and tda8295_probe was hard-coded to 0x4b, which is the default i2c address for those devices, but its possible for the device to be at an alternate address, 0x42, which is the case for the HVR-1950. If we probe the wrong address, probe fails and we have a non-working device. We have the actual address passed into the function by way of i2c_props, we just need to use it. Also fix up some copy/paste comment issues and streamline debug spew a touch. Verified to restore my HVR-1950 to full working order. Special thanks to Ken Bass for reporting the issue in the first place, and to both he and Gary Buhrmaster for aiding in debugging and analysis of the problem.

Will try again later The problem is that mb86a20s is only visible if the analog part is disabled. However, due to a trick at mb86a20s, it will later initialize properly: mb86a20s: mb86a20s_initfe: Initialization succeded. This is hacky and ugly. However, I coldn't find any easy way to fix it. A proper fix would be to have a resource locking schema, used by both V4L and DVB parts that would block access to analog registers while digital registers are in use, but this will probably put tda829x into a dead lock.

* | kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes2011-01-201-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

* [media] af9015: Fix max I2C message size when used with tda18271Mauro Carvalho Chehab2010-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | Changeset 1724c8fa7eb33d68898e060a08a8e6a88348b62f added an option to change the maximum I2C size to 8 bytes. However, it forgot to replace the previous usage at af9015 to use the newly defined macro value (TDA18271_16_BYTE_CHUNK_INIT). A latter changeset (e350d44fed8eb86a7192a579e3687fcd76a4645b) extended the possible values for .small_i2c field and, instead of using a random sequence of numbers, it used a number that makes more sense (e. g. the actual limit, in terms of bytes). However, as af9015 were using .small_i2c = 1, this become undefined, and the restriction of a max size of 16 was gone. While here, fix the reported msg size at tda18271-common.c.

* [media] tda18271: allow restricting max out to 4 bytesMauro Carvalho Chehab2010-10-212-27/+37
| | | | | | | | | | | | | | | By default, tda18271 tries to optimize I2C bus by updating all registers at the same time. Unfortunately, some devices doesn't support it. The current logic has a problem when small_i2c is equal to 8, since there are some transfers using 11 + 1 bytes. Fix the problem by enforcing the max size at the right place, and allows reducing it to max = 3 + 1.

| | | | | | | | | | | | | | | | | | | An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late) caused a new regression in the av7110 driver. Reverted the old fix and fixed the problem in the mxb driver instead. Tested on mxb and budget-av cards. The real problem is that the saa7146 framework has separate probe() and attach() driver callbacks which should be rolled into one. This is now done for the mxb driver, but others should do the same. Lack of hardware makes this hard to do, though. I hope to get hold of some hexium cards and then I can try to improve the framework to prevent this from happening again.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-3013-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
