2018-09-24media: hdmi.h: rename ADOBE_RGB to OPRGB and ADOBE_YCC to OPYCCHans Verkuil1-2/+2

2018-09-24media: replace ADOBERGB by OPRGBHans Verkuil1-1/+1
The CTA-861 standards have been updated to refer to opRGB instead of AdobeRGB. The official standard is in fact named opRGB, so switch to that. The two old defines referring to ADOBERGB in the public API are put under #ifndef __KERNEL__ and a comment mentions that they are deprecated.

2018-05-28media: adv7511: fix incorrect clear of CEC receive interruptHans Verkuil1-2/+2
If a CEC message was received and the RX interrupt was set, but not yet processed, and a new transmit was issues, then the transmit code would inadvertently clear the RX interrupt and after that no new messages would ever be received. Instead it should only clear TX interrupts since register 0x97 is a clear-on-write register.

2018-05-26media: adv7511: fix clearing of the CEC receive bufferHans Verkuil1-9/+9
The CEC receive buffer was not always cleared correctly. The datasheet was a bit confusing since sometimes it mentioned that the bit in CEC register 0x4a had to be toggled, and sometimes it suggested it was a 'Clear-on-write' bit. But it really needs to be toggled. The patch also enables/disables the CEC irqs after the other irq are enabled/disabled instead of doing it before. It may not matter, but it feels more logical to do it in that order, and the implementation that we (Cisco) have used until now and that is known to be reliable also did it in that order.

2016-07-12[media] adv7511: fix quantization range handlingHans Verkuil1-13/+17
Commit 1fb69bfd29e4b2e5e93922105326dd6cbd5ef6eb (adv7511: improve colorspace handling) introduced a number of bugs, specifically with regards to YCbCr output and quantization range handling: - if the output is not RGB, then disable the full-to-limited range CSC matrix since that is meant for RGB formats. YCbCr formats are always limited range, so there is nothing to convert. (OK, full range YCbCr is possible, but we don't support that right now). - the mediabus code that was passed to adv7511_set_fmt was always cleared by the memset in adv7511_fill_format. This made it effectively impossible to select YCbCr output. - adv7511_set_fmt never updated the rgb quantization range.

2016-01-11[media] media framework: rename pads init function to media_entity_pads_init()Mauro Carvalho Chehab1-1/+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. 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 Chehab1-1/+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.

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.

2015-03-23[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil1-7/+9
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.
