* [media] tuner-core: Change config from unsigned int to void *Ondrej Zary2013-04-08
| | | | | | | | | | | | | | config looks like a hack that was added to tuner-core to allow some configuration of TDA8290 tuner (it's not used by any other driver). But with the new configuration options of tda8290 driver (no_i2c_gate and std_map), it's no longer sufficient. Change config to be void * instead, which allows passing tuner-dependent config struct to drivers. Also update saa7134 driver to reflect this change (no other driver uses this).

* [media] exynos4-is: Allow colorspace conversion at FIMC-LITESylwester Nawrocki2013-04-04
| | | | | | | | | | | | | | | | | | | | | The FIMC-LITE output DMA allows to configure different YUV order than the order at the camera input interface. Thus there is some limited colorspace conversion possible. This patch makes the color format variable be per FIMC-LITE input/output, rather than a global per device. This also fixes incorrect behavior where color format at the FIMC-LITE.N subdev's source pad is modified by VIDIOC_S_FMT ioctl on the related video node. YUV order definitions are corrected so that we use notation: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] s5p-fimc: Add device tree based sensors registrationSylwester Nawrocki2013-03-31
| | | | | | | | | | | | | | | | | | | | The sensor (I2C and/or SPI client) devices are instantiated by their corresponding control bus drivers. Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.

Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver.

* [media] v4l2-ctrls: eliminate lockdep false alarms for struct ↵Andy Walls2013-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v4l2_ctrl_handler.lock When calling v4l2_ctrl_add_handler(), lockdep would detect a potential recursive locking problem on a situation that is by design intended and not a recursive lock. This happened because all struct v4l2_ctrl_handler.lock mutexes were created as members of the same lock class in v4l2_ctrl_handler_init(), and v4l2_ctrl_add_handler() takes the hdl->lock on two different v4l2_ctrl_handler instances. This change breaks the large lockdep lock class for struct v4l2_ctrl_handler.lock and breaks it into v4l2_ctrl_handler instantiation specific lock classes with meaningful class names. This will validly eliminate lockdep alarms for v4l2_ctrl_handler locking validation, as long as the relationships between drivers adding v4l2 controls to their own handler from other v4l2 drivers' control handlers remains straightforward. struct v4l2_ctrl_handler.lock lock classes are created with names such that the output of cat /proc/lockdep indicates where in the v4l2 driver code v4l2_ctrl_handle_init() is being called on instantiations: ffffffffa045f490 FD: 10 BD: 8 +.+...: cx2341x:1534:(hdl)->lock ffffffffa0497d20 FD: 12 BD: 2 +.+.+.: saa7115:1581:(hdl)->lock ffffffffa04ac660 FD: 14 BD: 2 +.+.+.: msp3400_driver:756:(hdl)->lock ffffffffa0484b90 FD: 12 BD: 1 +.+.+.: ivtv_gpio:366:(&itv->hdl_gpio)->lock ffffffffa04eb530 FD: 11 BD: 2 +.+.+.: cx25840_core:1982:(&state->hdl)->lock ffffffffa04fbc80 FD: 11 BD: 3 +.+.+.: wm8775:246:(&state->hdl)->lock Some lock chains, that were previously causing the recursion alarms, are now visible in the output of cat /proc/lockdep_chains: irq_context: 0 [ffffffffa0497d20] saa7115:1581:(hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04ac660] msp3400_driver:756:(hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa0484b90] ivtv_gpio:366:(&itv->hdl_gpio)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04eb530] cx25840_core:1982:(&state->hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04fbc80] wm8775:246:(&state->hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock Signed-off-by: Andy Walls <awalls@md.metrocast.net> [hans.verkuil@cisco.com: keep mutex_init in v4l2_ctrl_handler_init_class] Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | store_protocols() treats dev->rc_map.rc_type as a bitmap which is wrong for two reasons. First of all, it is pretty bogus to change the protocol type of the keymap just because the hardware has been asked to decode a different protocol. Second, dev->rc_map.rc_type is an enum (i.e. a single protocol) as pointed out by James Hogan <james.hogan@imgtec.com>.

Make it possible to specify additional GFP flags for those buffers by adding a gfp_flags field to vb2_queue.

* [media] davinci/dm644x_ccdc: fix compiler warningHans Verkuil2013-03-19
| | | | | | | | | | | | | | | | | drivers/media/platform/davinci/dm644x_ccdc.c: In function ‘validate_ccdc_param’: drivers/media/platform/davinci/dm644x_ccdc.c:233:32: warning: comparison between ‘enum ccdc_gama_width’ and ‘enum ccdc_data_size’ [-Wenum-compare] It took a bit of work, see this thread of an earlier attempt to fix this: https://patchwork.kernel.org/patch/1923091/ I've chosen not to follow the suggestions in that thread since gamma_width is really a different property from data_size. What you really want is to know if gamma_width fits inside data_size and for that you need to translate each enum into a maximum bit number so you can safely compare the two. So I put in two static inline translation functions instead, keeping the rest of the code the same (except for fixing the 'gama' typo).

* [media] vb2: Add support for non monotonic timestampsKamil Debski2013-03-05
| | | | | | | | | | | | | | | | Not all drivers use monotonic timestamps. This patch adds a way to set the timestamp type per every queue. In addition, set proper timestamp type in drivers that I am sure that use either MONOTONIC or COPY timestamps. Other drivers will correctly report UNKNOWN timestamp type instead of assuming that all drivers use monotonic timestamps.

* [media] media: ov7670: Add possibility to disable pixclk during hblankJavier Martin2013-02-08
| | | | | | | | | | Some bridge drivers capture pixels during blanking periods if pixclk is enabled. In order to avoid capturing bogus data we need to disable pixclk in the sensor during those blanking periods.

* [media] media: ov7670: add possibility to bypass pll for ov7675Javier Martin2013-02-08
| | | | | | | | | | | | For a frame rate of 30 fps a pixclk of 24MHz is needed. For those cases where the ov7670 has a clean 24MHz input (xvclk) the PLL can be bypassed. This will result in a value of clkrc of 1, which means that in practice pixclk = xvclk (input clock) Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Javier Martin <javier.martin@vista-silicon.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
