2020-04-16media: media/test_drivers: rename to test-driversHans Verkuil
We never use _ in directory names in the media subsystem, so rename to test-drivers instead for consistency. Also update MAINTAINERS with the new path. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-16media: i2c/Kconfig: use sub-menus for I2C supportMauro Carvalho Chehab
There are *lots* of I2C ancillary drivers. While we're using comments to group them, all options appear at the same menu. It should be a lot clearer to group them into sub-menus, with may help people to go directly to the driver(s) he's needing to enable.

2020-04-15media: place CEC menu before MEDIA_SUPPORTMauro Carvalho Chehab
The only item that opens at the CEC Kconfig menu is related to Remote Controller. Also, its support should not depend on media support, so it makes sense to keep both RC and CEC together.

2020-04-14media: Kconfig: fix selection for test driversMauro Carvalho Chehab
There are some long-time mistakes related to build test drivers, with regards to depends on/select. Also, as we now want to build any test driver without needing to enable anything else, change the logic in order to properly filter them. Please notice that the PCI skeleton is somewhat an exception, as it requires to select *both* SAMPLES and MEDIA_TEST_SUPPORT. I almost changed it to be either one, but decided to keep it as-is, as this is something that we don't really need to be included on any distribution. The only reason for someone to build it is for COMPILE_TEST purposes. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-04-14media: Kconfig: better support hybrid TV devicesMauro Carvalho Chehab
Right now, if one has an hybrid TV card, it has to select both analog and digital TV support, as otherwise the needed core support won't be selected. Change the logic to auto-select the core support for those drivers, as this is a way more intuitive. It should be noticed that, as now both DVB_CORE and VIDEO_DEV defaults depends on selecting a hybrid cards, we had to remove the explicit dependencies there, in order to avoid circular dependencies. That requires some tricks: 1) the prompt should not be not visible when an hybrid card is selected, as the user shold not change it. 2) When a media hybrid device is selected, the modular option for DVB_CORE and VIDEO_DEV will follow the MEDIA_SUPPORT dependency, as we can't have a core built with "y" with a driver built as module. Note: while here, moved two pure V4L2 PCI drivers out of the "hybrid" part of config and consider pvrusb2 as an hybrid device. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2020-04-14media: split test drivers from platform directoryMauro Carvalho Chehab
When the first test device was added (vivi.c), there were just one file. I was too lazy on that time to create a separate directory just for it, so I kept it together with platform. Now, we have vivid, vicodec, vim2m and vimc. Also, a new virtual driver has been prepared to support DVB API. So, it is time to solve this mess, by placing test stuff on a separate directory. It should be noticed that we also have some skeleton drivers (for V4L and for DVB). For now, we'll keep them separate, as they're not really test drivers, but instead, just examples. The DVB frontend ones will likely be part of a new DVB test driver. By that time, it should make sense to move them here as well. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2019-08-19media: Clarify how menus are hidden by SUBDRV_AUTOSELECTEzequiel Garcia
Some users have been having a hard time finding the hidden menus. A typically case are camera sensor drivers (e.g IMX219, OV5645, etc), which are common on embedded platforms and not really "ancillary" devices. The problem with MEDIA_SUBDRV_AUTOSELECT seems to be related to the fact that it uses the "visible" syntax to hide the menus. This is not obvious and it normally takes some time to figure out. To fix the problem, add a comment on each of hidden menus, which should clarify what option is causing menus to be hidden.

2019-05-24media: remove redundant 'default n' from Kconfig-sBartlomiej Zolnierkiewicz
'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

2017-07-18media: cec-pin: add low-level pin hardware supportHans Verkuil
Add support for CEC hardware that relies on low-level pin polling or GPIO interrupts. One example is the Allwinner SoC. But any GPIO-based CEC implementation can use this as well. A GPIO implementation is very suitable as well for debugging: it can use interrupts to detect state changes and report it. Userspace can then verify if the bus traffic is correct. This also makes error injection possible. The disadvantage is that it is hard to get the timings right since linux isn't a hard realtime system. In general on an idle system it works quite well, but under load the timer will miss its mark every so often. The debugfs file /sys/kernel/debug/cec/cecX/status gives some statistics with respect to the timer overruns. When the adapter is unconfigured and the low-level driver supports interrupts, then the interrupt will be used to detect changes. This should be quite accurate. But when the adapter is configured a hrtimer has to be used. The hrtimer implements a state machine where for each state the code will read the bus or drive the bus and go on to the next state. It will re-arm the timer with a delay based on the next state.

2017-06-04[media] cec: select CEC_CORE instead of depend on itHans Verkuil
The CEC framework is used by both drm and media. That makes it tricky to get the dependencies right. This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options out of the media menu and instead drivers that want to use CEC should select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

2017-04-19[media] cec: Kconfig cleanupHans Verkuil
The Kconfig options for the CEC subsystem were a bit messy. In addition there were two cec sources (cec-edid.c and cec-notifier.c) that were outside of the media/cec directory, which was weird. Move those sources to media/cec as well. The cec-edid and cec-notifier functionality is now part of the cec module and these are no longer separate modules. Also remove the MEDIA_CEC_EDID config option and include it with the main CEC config option (which defined CEC_EDID anyway). Added static inlines to cec-edid.h for dummy functions when CEC_CORE isn't defined. CEC drivers should now depend on CEC_CORE. CEC drivers that need the cec-notifier functionality must explicitly select CEC_NOTIFIER. The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of CEC_CORE, fix that as well.
