* [media] R820T tuner needs CONFIG_BITREVERSEArnd Bergmann2015-05-131-0/+1
| | | | | | | | | | | | | | | In a rarely hit randconfig case, the r820t tuner driver can get built when CONFIG_BITREVERSE is not selected by any other driver, resulting in this error: drivers/built-in.o: In function `r820t_read.constprop.3': :(.text+0xa0594): undefined reference to `byte_rev_table' For consistency, this adds the 'select BITREVERSE' that all other similar drivers have.

* [media] si2157: support selection of IF interfaceOlli Salonen2015-05-123-1/+10
| | | | | | | | | | | | | | The chips supported by the si2157 driver have two IF outputs (either pins 12+13 or pins 9+11). Instead of hardcoding the output to be used add an option to choose which output shall be used. As this patch changes the default behaviour, the IF interface is specified in each driver currently using si2157 driver. This is to keep bisectability.

* | | [media] Add and use IS_REACHABLE macroArnd Bergmann2015-04-0827-27/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the media drivers, the v4l2 core knows about all submodules and calls into them from a common function. However this cannot work if the modules that get called are loadable and the core is built-in. In that case we get drivers/built-in.o: In function `set_type': drivers/media/v4l2-core/tuner-core.c:301: undefined reference to `tea5767_attach' drivers/media/v4l2-core/tuner-core.c:307: undefined reference to `tea5761_attach' drivers/media/v4l2-core/tuner-core.c:349: undefined reference to `tda9887_attach' drivers/media/v4l2-core/tuner-core.c:405: undefined reference to `xc4000_attach' This was working previously, until the IS_ENABLED() macro was used to replace the construct like #if defined(CONFIG_DVB_CX24110) || (defined(CONFIG_DVB_CX24110_MODULE) && defined(MODULE)) with the difference that the new code no longer checks whether it is being built as a loadable module itself. To fix this, this new patch adds an 'IS_REACHABLE' macro, which evaluates true in exactly the condition that was used previously. The downside of this is that this trades an obvious link error for a more subtle runtime failure, but it is clear that the change that introduced the link error was unintentional and it seems better to revert it for now. Also, a similar change was originally created by Trent Piepho and then reverted by teh change to the IS_ENABLED macro. Ideally Kconfig would be used to avoid the case of a broken dependency, or the code restructured in a way to turn around the dependency, but either way would require much larger changes here.

Because release_firmware() was always being called, it would work fine as expected on the first call but then the second call would corrupt aribtrary memory. Set the pointer to NULL after releasing so that we don't call release_firmware() twice. This problem was detected in the HVR-950q where plugging/unplugging the device multiple times would intermittently show panics in completely unrelated areas of the kernel.

* [media] mxl301rf: add driver for MaxLinear MxL301RF OFDM tunerAkihiro Tsukada2014-09-234-0/+383
| | | | | | | | | | | | | | | This patch adds driver for mxl301rf OFDM tuner chips. It is used as an ISDB-T tuner in earthsoft pt3 cards. Note that this driver does not initilize the chip, because the initilization sequence / register setting is not disclosed. Thus, the driver assumes that the chips are initilized externally by its parent board driver before tuner_ops->init() are called, like in PT3 driver where the bridge chip contains the init sequence in its private memory and provides a command to trigger the sequence.

* [media] media: tuner xc5000 - try to avoid firmware load in resume pathShuah Khan2014-09-231-1/+15
| | | | | | | | | | | | | xc5000 doesn't load firmware at attach time instead loads it when it needs to set and change configuration from its init, frequency, digital and analog mode set interffaces. As a result, when system is suspended before firmware is loaded, firmware load can be avoided during resume. Loading formware in this scenario results in slowpath warnings during resume as it won't be in the suspend firmware cache.

* [media] media: tuner xc5000 - release firmwware from xc5000_release()Shuah Khan2014-09-231-14/+20
| | | | | | | | | | | xc5000 releases firmware right after loading it. Change it to save the firmware and release it from xc5000_release(). This helps avoid fecthing firmware when forced firmware load requests come in to change analog tv frequence and when firmware needs to be reloaded after suspend and resume.
