* [media] tc358743: Add OF device ID tableJavier Martinez Canillas2017-04-171-0/+9
| | | | | | | | | | | | | The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

| | | | | | | | | | | | | | | | | | | | | | | | While testing with CONFIG_UBSAN, I got this warning: drivers/media/i2c/tc358743.c: In function 'tc358743_probe': drivers/media/i2c/tc358743.c:1930:1: error: the frame size of 2480 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] The problem is that the i2c_rd8/wr8/rd16/... functions in this driver pass a pointer to a local variable into a common function, and each call to one of them adds another variable plus redzone to the stack. I also noticed that the way this is done is broken on big-endian machines, as we copy the registers in CPU byte order. To address both those problems, I'm adding two helper functions for reading a register of up to 32 bits with correct endianess and change all other functions to use that instead. Just to be sure we don't get the problem back with changed optimizations in gcc, I'm also marking the new functions as 'noinline', although my tests with gcc-7 don't require that.

* [media] tc358743: Disable HDCP with "manual HDCP authentication" bitMats Randgaard2017-02-031-20/+12Star
| | | | | | | | | | | | | | | | | | | | | | | | Originally Toshiba told us that the only way to disable HDCP was to set the receiver in repeater mode, that would make the authentication fail because of missing software support. It has worked fine with all the sources we and our customers has used, until it was reported problems with Apple MacBook (Retina, 12-inch, Early 2015) (https://support.apple.com/kb/SP712?locale=en_US&viewlocale=en_US) with Apple A1612 USB type-C multiport adapter (http://www.apple.com/shop/product/MJ1K2AM/A/usb-c-digital-av-multiport-adapter) Finally Toshiba came up with a hidden bit that is named "Manual HDCP authentication". In this patch the original "repeater mode" concept is removed, and the new bit is set instead. With his patch HDCP is disabled when connected to the Apple MacBook and all other sources we have tested so far. The Apple MacBook is constantly trying to authenticate, but fails and continues to transmit unencrypted video.

* [media] tc358743: Do not read number of CSI lanes in use from chipMats Randgaard2017-02-031-7/+7
| | | | | | | | | | | | | | | The number of CSI lanes that should be used is set to the CSI_CONTROL register by indirectly writing to the CSI_CONFW register. When the number of lanes is read back from the CSI_CONTROL register the value is usually correct, but we have seen that it suddenly is 1 for a short moment before the correct value is restored again. Toshiba have not figured out why that happen, but we have found it safer to store the value in the driver.

* [media] tc358743: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar2016-07-081-14/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | The workqueue "work_queues" enables hotplugging. It has a single work item(&state->delayed_work_enable_hotplug) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Work item has been sync cancelled in tc358743_remove() to ensure that there are no pending tasks while disconnecting the driver.

* [media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab2016-01-111-1/+1
| | | | | | | | | | | | | | | | | 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: get rid of unused "extra_links" param on media_entity_init()Mauro Carvalho Chehab2016-01-111-1/+1
| | | | | | | | | | | | | | | | | | 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 Chehab2015-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, include/media is messy, as it contains both the V4L2 core headers and some driver-specific headers on the same place.

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.
