2017-08-20media: omap3isp: Quit using struct v4l2_subdev.host_priv fieldSakari Ailus
struct v4l2_subdev.host_priv is intended to be used by another driver. This is hardly good design but back in the days of platform data was a quick hack to get things done. As the sub-device specific bus information can be stored to the ISP driver specific struct allocated along with v4l2_async_subdev, keep the information there and only there.

2017-08-20media: omap3isp: csiphy: Don't assume the CSI receiver is a CSI2 moduleSakari Ailus
The CSI PHY is associated with a CSI receiver. The code assumes this receiver is a CSI2 module and relies on the CSI2 module object heavily to access the ISP or pipeline objects. However, the receiver could also be a CSI1/CCP2 module. Pass a new CSI receiver entity pointer to the CSI PHY acquire function, and replace all hardcoded usage of the CSI2 module with that CSI receiver entity.

2016-10-21[media] omap3isp: don't break long linesMauro Carvalho Chehab
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-01-11[media] omap3isp: remove per ISP module link creation functionsJavier Martinez Canillas
The entities to video nodes links were created on separate functions for each ISP module but since the only thing that these functions do is to call media_create_pad_link(), there's no need for that indirection level and all link creation logic can be just inlined in the caller function. Also, since the only possible failure for the link creation is a memory allocation, there is no need for error messages since the core already reports a very verbose message in that case.

2016-01-11[media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab
With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-01-11[media] omap3/omap4/davinci: get rid of MEDIA_ENT_T_V4L2_SUBDEV abuseMauro Carvalho Chehab
On omap3/omap4/davinci drivers, MEDIA_ENT_T_V4L2_SUBDEV macro is abused in order to "simplify" the pad checks. Basically, it does a logical or of this macro, in order to check for a local index and if the entity is either a subdev or not. As we'll get rid of MEDIA_ENT_T_V4L2_SUBDEV macro, replace it by 2 << 16 where it occurs, and add a note saying that the code there is actually a hack.

2016-01-11[media] omap3isp: separate links creation from entities initJavier Martinez Canillas
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.

2016-01-11[media] media: rename the function that create pad linksMauro Carvalho Chehab
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>
2016-01-11[media] media: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab
Currently, media_entity_init() creates an array with the links, allocated at init time. It provides a parameter (extra_links) that would allocate more links than the current needs, but this is not used by any driver. As we want to be able to do dynamic link allocation/removal, we'll need to change the implementation of the links. So, before doing that, let's first remove that extra unused parameter, in order to cleanup the interface first.

2015-04-02[media] omap3isp: Refactor device configuration structs for Device TreeSakari Ailus
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.

2015-03-23[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil
If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.
