The soc_camera driver is about to be removed, so drop camera support from this board. Note that the soc_camera driver itself has long since been deprecated and can't be compiled anymore (it depends on BROKEN), so camera support on this board has been broken for a long time (at least since 4.9 when the pxa_camera.c was removed from soc_camera). Note that there is a new pxa_camera.c driver that replaced the old soc_camera based driver, but using that would require these boards to be converted to use the device tree. Signed-off-by:

The functions mtk_mdp_register/unregister_component have been created to add / remove items from the list of components. This will eventually enable us to specify a list of components in the device tree instead of hardcoding them into this driver. The list is modified by a single thread at driver probe time, and will not be traversed by another thread until the call to pm_runtime_enable at the end of probing. Signed-off-by:

The mtk-mdp driver uses states to check if the formats have been set on the capture and output when turning the streaming on, setting controls or setting the selection rectangles. Those states are reset when 0 buffers are requested like when checking capabilities. This patch removes all format checks and set one by default as queues in V4L2 are expected to always have a format set. https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-streamon.html https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-g-ctrl.html https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/vidioc-g-selection.htmlSigned-off-by:

If fw_csr_string() returns -ENOENT, then "name" is uninitialized. So then the "strlen(model_names[i]) <= name_len" is true because strlen() is unsigned and -ENOENT is type promoted to a very high positive value. Then the "strncmp(name, model_names[i], name_len)" uses uninitialized data because "name" is uninitialized. Fixes: 92374e88 ("[media] firedtv: drop obsolete backend abstraction") Signed-off-by:

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Currently for msm_csiphy, msm_csid, and msm_ispif subdevices the media entity function field is set to MEDIA_ENT_F_IO_V4L. This is incorrect as MEDIA_ENT_F_IO_V4L implies V4L2 video node. Change it to MEDIA_ENT_F_PROC_VIDEO_PIXEL_FORMATTER as this is the best fit from the functions defined in include/uapi/linux/media.h. Signed-off-by:

According to https://www.kernel.org/doc/Documentation/gpio/consumer.txt, - all of the gpiod_set_value_xxx() functions operate with the *logical* value. So in imx290_power_on() the reset signal should be cleared (de-asserted) with gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in imx290_power_off() the value of 1 must be used to apply/assert the reset to the sensor. In the device tree the reset pin is described as GPIO_ACTIVE_LOW, and gpiod_set_value_xxx() functions take this into account, - when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is not initialized, and the direction must be set later; using a GPIO without setting its direction first is illegal and will result in undefined behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this asserts the reset signal to the sensor initially). Signed-off-by:

With the current driver 'media-ctl -p' issued right after the imx290 driver is loaded prints: pad0: Source [fmt:unknown/0x0] The format value of zero is due to the current_format field of the imx290 struct not being initialized yet. As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field is also initialized, so the line which set current_mode to a default value in driver's probe() function is no longer needed.
