* [media] media: i2c: m5mols: m5mols_core: constify v4l2_subdev_pad_ops structuresBhumika Goyal2017-02-03

| | | | | | | | | | | | Smatch complains that there are some paths where "status" isn't initialized. The code does assume that m5mols_read_u8() can fail so it seems as if Smatch is correct. Let's initialize it to REG_ISO_AUTO which is zero.

* [media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | 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.

* [media] media-entity.h: rename entity.type to entity.functionMauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | Entities should have one or more functions. Calling it as a type proofed to not be correct, as an entity could eventually have more than one type. So, rename the field as function. Please notice that this patch doesn't extend support for multiple function entities. Such change will happen when we have real case drivers using it.

* [media] media: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab2016-01-11
| | | | | | | | | | | | | | | | | | 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.

* [media] include/media: split I2C headers from V4L2 coreMauro Carvalho Chehab2015-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place. That makes harder to identify what core headers should be documented and what headers belong to I2C drivers that are included only by bridge/main drivers that would require the functions provided by them. Let's move those i2c specific files to its own subdirectory. The files to move were produced via the following script: mkdir include/media/i2c (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done) for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done And the references corrected via this script: MAIN_DIR="media/" PREV_DIR="media/" DIRS="i2c/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

* [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil2015-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
