2016-05-20Merge branch 'i2c/for-4.7' of ↵Linus Torvalds3-26/+31
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: - Peter Rosin did some major rework on the locking of i2c muxes by seperating parent-locked muxes and mux-locked muxes. This avoids deadlocks/workarounds when the mux itself needs i2c commands for muxing. And as a side-effect, other workarounds in the media layer could be eliminated. Also, Peter stepped up as the i2c mux maintainer and will keep an eye on these changes. - major updates to the octeon driver - add a helper to the core to generate the address+rw_bit octal and make drivers use it - quite a bunch of driver updates * 'i2c/for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (84 commits) i2c: rcar: add DMA support i2c: st: Implement bus clear i2c: only check scl functions when using generic recovery i2c: algo-bit: declare i2c_bit_quirk_no_clk_stretch as static i2c: tegra: disable clock before returning error [media] rtl2832: regmap is aware of lockdep, drop local locking hack [media] rtl2832_sdr: get rid of empty regmap wrappers [media] rtl2832: change the i2c gate to be mux-locked [media] si2168: change the i2c gate to be mux-locked iio: imu: inv_mpu6050: change the i2c gate to be mux-locked i2c: mux: document i2c muxes and elaborate on parent-/mux-locked muxes i2c: mux: relax locking of the top i2c adapter during mux-locked muxing i2c: muxes always lock the parent adapter i2c: allow adapter drivers to override the adapter locking i2c: uniphier: add "\n" at the end of error log i2c: mv64xxx: remove CONFIG_HAVE_CLK conditionals i2c: mv64xxx: use clk_{prepare_enable,disable_unprepare} i2c: mv64xxx: handle probe deferral for the clock i2c: mv64xxx: enable the driver on ARCH_MVEBU i2c: octeon: Add workaround for broken irqs on CN3860 ...

2016-01-11[media] media-device: split media initialization and registrationJavier Martinez Canillas1-16/+16
The media device node is registered and so made visible to user-space before entities are registered and links created which means that the media graph obtained by user-space could be only partially enumerated if that happens too early before all the graph has been created. To avoid this race condition, split the media init and registration in separate functions and only register the media device node when all the pending subdevices have been registered, either explicitly by the driver or asynchronously using v4l2_async_register_subdev(). The media_device_register() had a check for drivers not filling dev and model fields but all drivers in mainline set them and not doing it will be a driver bug so change the function return to void and add a BUG_ON() for dev being NULL instead. Also, add a media_device_cleanup() function that will destroy the graph_mutex that is initialized in media_device_init().

2016-01-11[media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab1-2/+2
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] media: convert links from array to listMauro Carvalho Chehab1-5/+3
The entire logic that represent graph links were developed on a time where there were no needs to dynamic remove links. So, although links are created/removed one by one via some functions, they're stored as an array inside the entity struct. As the array may grow, there's a logic inside the code that checks if the amount of space is not enough to store the needed links. If it isn't the core uses krealloc() to change the size of the link, with is bad, as it leaves the memory fragmented. So, convert links into a list. Also, currently, both source and sink entities need the link at the graph traversal logic inside media_entity. So there's a logic duplicating all links. That makes it to spend twice the memory needed. This is not a big deal for today's usage, where the number of links are not big. Yet, if during the MC workshop discussions, it was said that IIO graphs could have up to 4,000 entities. So, we may want to remove the duplication on some future. The problem is that it would require a separate linked list to store the backlinks inside the entity, or to use a more complex algorithm to do graph backlink traversal, with is something that the current graph traversal inside the core can't cope with. So, let's postpone a such change if/when it is actually needed. It should also be noticed that the media_link structure uses 44 bytes on 32-bit architectures and 84 bytes on 64-bit architecture. It will thus be allocated out of the 64-bytes and 96-bytes pools respectively. That's a 12.5% memory waste on 64-bit architectures and 31.25% on 32-bit architecture. A linked list is less efficient than an array in this case, but this could later be optimized if we can get rid of the reverse links (with would reduce memory allocation by 50%).

2016-01-11[media] media: rename the function that create pad linksMauro Carvalho Chehab1-3/+3

2016-01-11[media] media: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab1-2/+2
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.

Let's not mix headers used by the core with those headers that are needed by some driver-specific interface header.

2015-11-17[media] include/media: split I2C headers from V4L2 coreMauro Carvalho Chehab1-1/+1
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.

Fix this compiler warning by allocating a structure to read the eeprom instead of doing it on the stack and worse: the eeprom array is static, so that can cause problems if there are multiple cx231xx instances. cx231xx-cards.c: In function 'cx231xx_card_setup': cx231xx-cards.c:1110:1: warning: the frame size of 2064 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ I did consider removing the code altogether since the result is actually not used at the moment, but I decided against it since it is used in other drivers and someone might want to start using it in this driver as well. And then it is useful that the code is already there. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2015-05-12[media] si2157: support selection of IF interfaceOlli Salonen1-0/+2
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.

2015-03-02[media] use a function for DVB media controller registerMauro Carvalho Chehab1-3/+1
This is really a simple function, but using it avoids to have if's inside the drivers. Also, the kABI becomes a little more clearer. This shouldn't generate any overhead, and the type check will happen when compiling with MC DVB enabled. So, let's do it. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
