* [media] media: use macros to check for V4L2 subdev entitiesMauro Carvalho Chehab2016-01-111-8/+6
| | | | | | | | | | | | | | | | | | Instead of relying on media subtype, use the new macros to detect if an entity is a subdev or an A/V DMA entity. Please note that most drivers assume that there's just AV_DMA or V4L2 subdevs. This is not true anymore, as we've added MC support for DVB, and there are plans to add support for ALSA and FB/DRM too. Ok, on the current pipelines supported by those drivers, just V4L stuff are there, but, assuming that some day a pipeline that also works with other subsystems will ever added, it is better to add explicit checks for the AV_DMA stuff.

* [media] omap3isp: create links after all subdevs have been boundJavier Martinez Canillas2016-01-111-8/+15
| | | | | | | | | | | | | | | | | | The omap3isp driver parses the graph endpoints to know how many subdevices needs to be registered async and register notifiers callbacks for to know when these are bound and when the async registrations are completed. Currently the entities pad are linked with the correct ISP input interface when the subdevs are bound but it happens before entitities are registered with the media device so that won't work now that the entity links list is initialized on device registration. So instead creating the pad links when the subdevice is bound, create them on the complete callback once all the subdevices have been bound but only try to create for the ones that have a bus configuration set during bound.

* [media] omap3isp: separate links creation from entities initJavier Martinez Canillas2016-01-111-54/+98
| | | | | | | | | | | | | | The omap3isp driver initializes the entities and creates the pads links before the entities are registered with the media device. This does not work now that object IDs are used to create links so the media_device has to be set. Split out the pads links creation from the entity initialization so the links are created after the entities have been registered with the media device.

* [media] media: use entity.graph_obj.mdev instead of .parentJavier Martinez Canillas2016-01-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The struct media_entity has a .parent field that stores a pointer to the parent struct media_device. But recently a media_gobj was embedded into the entities and since struct media_gojb already has a pointer to a struct media_device in the .mdev field, the .parent field becomes redundant and can be removed. This patch replaces all the usage of .parent by .graph_obj.mdev so that field will become unused and can be removed on a later patch. No functional changes. The transformation was made using the following coccinelle spatch: @@ struct media_entity *me; @@ - me->parent + me->graph_obj.mdev @@ struct media_entity *link; @@ - link->source->entity->parent + link->source->entity->graph_obj.mdev @@ struct exynos_video_entity *ve; @@ - ve->vdev.entity.parent + ve->vdev.entity.graph_obj.mdev Suggested-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] media: rename the function that create pad linksMauro Carvalho Chehab2016-01-111-9/+9
| | | | | | | | | | | | | | | | | With the new API, a link can be either between two PADs or between an interface and an entity. So, we need to use a better name for the function that create links between two pads. So, rename the such function to media_create_pad_link(). No functional changes. This patch was created via this shell script: for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f) $(find include/ -name '*.h' -type f) ; do sed s,media_entity_create_link,media_create_pad_link,g <$i >a && mv a $i; done Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Tested-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] v4l: omap3isp: Fix sub-device power management codeSakari Ailus2015-07-061-2/+2
| | | | | | | | | | | | | | | | Commit 813f5c0ac5cc ("media: Change media device link_notify behaviour") modified the media controller link setup notification API and updated the OMAP3 ISP driver accordingly. As a side effect it introduced a bug by turning power on after setting the link instead of before. This results in sub-devices not being powered down in some cases when they should be. Fix it.

* [media] omap3isp: Refactor device configuration structs for Device TreeSakari Ailus2015-04-021-44/+42
| | | | | | | | | | | | | | | | | | | | Make omap3isp configuration data structures more suitable for consumption by the DT by separating the I2C bus information of all the sub-devices in a group and the ISP bus information from each other. The ISP bus information is made a pointer instead of being directly embedded in the struct. In the case of the DT only the sensor specific information on the ISP bus configuration is retained. The structs are renamed to reflect that. After this change the structs needed to describe device configuration can be allocated and accessed separately without those needed only in the case of platform data. The platform data related structs can be later removed once the support for platform data can be removed.

* [media] media: Change media device link_notify behaviourSylwester Nawrocki2013-06-121-16/+25
| | | | | | | | | | | | | | | | | | | | | | | | Currently the media device link_notify callback is invoked before the actual change of state of a link when the link is being enabled, and after the actual change of state when the link is being disabled. This doesn't allow a media device driver to perform any operations on a full graph before a link is disabled, as well as performing any tasks on a modified graph right after a link's state is changed. This patch modifies signature of the link_notify callback. This callback is now called always before and after a link's state change. To distinguish the notifications a 'notification' argument is added to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates notification before link's state change and MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after link flags change.

It contains, among other things: - OMAP PM fixes and some patches for audio device integration - OMAP clock fixes related to common clock conversion - A set of patches cleaning up WFI entry and blocking. - A set of fixes and IP block support for PM on TI AM33xx SoCs (Beaglebone, etc) - A set of smaller fixes and cleanups around AM33xx restart and revision detection, as well as removal of some dead code (CONFIG_32K_TIMER_HZ)" * tag 'late-omap' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (34 commits) ARM: omap2: include linux/errno.h in hwmod_reset ARM: OMAP2+: fix some omap_device_build() calls that aren't compiled by default ARM: OMAP4: hwmod data: Enable AESS hwmod device ARM: OMAP4: hwmod data: Update AESS data with memory bank area ARM: OMAP4+: AESS: enable internal auto-gating during initial setup ASoC: TI AESS: add autogating-enable function, callable from architecture code ARM: OMAP2+: hwmod: add enable_preprogram hook ARM: OMAP4: clock data: Add missing clkdm association for dpll_usb ARM: OMAP2+: PM: Fix the dt return condition in pm_late_init() ARM: OMAP2: am33xx-hwmod: Fix "register offset NULL check" bug ARM: OMAP2+: AM33xx: hwmod: add missing HWMOD_NO_IDLEST flags ARM: OMAP: AM33xx hwmod: Add parent-child relationship for PWM subsystem ARM: OMAP: AM33xx hwmod: Corrects PWM subsystem HWMOD entries ARM: DTS: AM33XX: Add nodes for OCMC RAM and WKUP-M3 ARM: OMAP2+: AM33XX: Update the hardreset API ARM: OMAP2+: AM33XX: hwmod: Update the WKUP-M3 hwmod with reset status bit ARM: OMAP2+: AM33XX: hwmod: Fixup cpgmac0 hwmod entry ARM: OMAP2+: AM33XX: hwmod: Update TPTC0 hwmod with the right flags ARM: OMAP2+: AM33XX: hwmod: Register OCMC RAM hwmod ARM: OMAP2+: AM33XX: CM/PRM: Use __ASSEMBLER__ macros in header files ...
| * omap3isp: Set cam_mclk rate directlyLaurent Pinchart2013-01-231-16/+2
| | | | | | | | | | | | | | | | | | | | | | Now that the cam_mclk rate changes are back-propagated to dpll4_m5_ck we can set the cam_mclk rate directly instead of manually setting the rate of the parent clock.

* Drivers: media: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-3/+3
| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* ARM: OMAP2+: Drop plat/cpu.h for omap2plusTony Lindgren2012-12-171-2/+0
| | | | | | | | | | | | | | | | The cpu_is_omap macros are now local to arch/arm/mach-omap2 in soc.h and plat/cpu.h can finally be dropped for omap2+. Thanks everybody for help with fixing the drivers. Note that we can now also remove the unused plat/cpu.h from smartreflex.c and isp.c as they will cause compile errors with ARCH_MULTIPLATFORM enabled.
