2016-07-08[media] vb2: replace void *alloc_ctxs by struct device *alloc_devsHans Verkuil
Make this a proper typed array. Drop the old allocate context code since that is no longer used. Note that the memops functions now get a struct device pointer instead of the struct device ** that was there initially (actually a void pointer to a struct containing only a struct device pointer). This code is now a lot cleaner.

2016-04-13[media] soc_camera: rcar_vin: add R-Car Gen 2 and 3 fallback compatibility ↵Yoshihiro Kaneko
strings Add fallback compatibility string for R-Car Gen 1 and 2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, e.g. Gen 2 and 3. But beyond that it's unclear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme being adopted for drivers for Renesas SoCs.

2016-04-13[media] sh_mobile_ceu_camera: Remove dependency on SUPERHSimon Horman
A dependency on ARCH_SHMOBILE seems to be the best option for sh_mobile_ceu_camera: * For Super H based SoCs: sh_mobile_ceu is used on SH_AP325RXA, SH_ECOVEC, SH_KFR2R09, SH_MIGOR, and SH_7724_SOLUTION_ENGINE which depend on CPU_SUBTYPE_SH7722, CPU_SUBTYPE_SH7723, or CPU_SUBTYPE_SH7724 which all select ARCH_SHMOBILE. * For ARM Based SoCs: Since the removal of legacy (non-multiplatform) support this driver has not been used by any Renesas ARM based SoCs. The Renesas ARM based SoCs currently select ARCH_SHMOBILE, however, it is planned that this will no longer be the case. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

2015-12-18[media] vb2: drop v4l2_format argument from queue_setupHans Verkuil
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-11-17[media] include/media: move platform_data to linux/platform_data/mediaMauro Carvalho Chehab
Let's not mix platform_data headers with the core headers. Instead, let's create a subdir at linux/platform_data and move the headers to that common place, adding it to MAINTAINERS. The headers were moved with: mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/ And the references fixed with this script: MAIN_DIR="linux/platform_data/" PREV_DIR="media/" DIRS="media/" 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 Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
2015-11-17[media] include/media: move driver interface headers to a separate dirMauro Carvalho Chehab
Let's not mix headers used by the core with those headers that are needed by some driver-specific interface header. The headers used on drivers were manually moved using: mkdir include/media/drv-intf/ git mv include/media/cx2341x.h include/media/cx25840.h \ include/media/exynos-fimc.h include/media/msp3400.h \ include/media/s3c_camif.h include/media/saa7146.h \ include/media/saa7146_vv.h include/media/sh_mobile_ceu.h \ include/media/sh_mobile_csi2.h include/media/sh_vou.h \ include/media/si476x.h include/media/soc_mediabus.h \ include/media/tea575x.h include/media/drv-intf/ And the references for those headers were corrected using: MAIN_DIR="media/" PREV_DIR="media/" DIRS="drv-intf/" 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 Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

2015-09-25[media] rcar_vin: call g_std() instead of querystd()Sergei Shtylyov
Hans Verkuil says: "The only place querystd can be called is in the QUERYSTD ioctl, all other ioctls should use the last set standard." So call the g_std() subdevice method instead of querystd() in the driver's set_fmt() method.

2015-09-25[media] rcar_vin: propagate querystd() error upstreamSergei Shtylyov
rcar_vin_set_fmt() defaults to PAL when the subdevice's querystd() method call fails (e.g. due to I2C error). This doesn't work very well when a camera being used outputs NTSC which has different order of fields and resolution. Let us stop pretending and return the actual error except when the querystd() method is not implemented, in which case we'll have to set the 'field' variable to V4L2_FIELD_NONE. Note that doing this would prevent video capture on at least Renesas Henninger/ Porter boards where I2C seems particularly buggy.
