2019-02-18media: ov5640: Move test_pattern_menu before ov5640_set_ctrl_test_patternChen-Yu Tsai1-5/+5
The OV5640 has many options for generating test patterns. Unfortunately there is only one V4L2 control for it. Thus the driver would need to list some or all combinations. Move the test_pattern_menu list before the ov5640_set_ctrl_test_pattern function that programs the hardware. This would allow us to add a matching list of values to program into the hardware, while keeping the two lists together for ease of maintenance.

2019-02-18media: i2c: adv748x: Convert SW reset routine to functionKieran Bingham2-10/+38
The ADV748x is currently reset by writting a small table of registers to the device. The table lacks documentation and contains magic values to perform the actions, including using a fake register address to introduce a delay loop. Remove the table, and convert to code, documenting the purpose of the specific writes along the way.

2019-02-18media: adv748x: Implement TX link_setup callbackJacopo Mondi2-1/+49
When the adv748x driver is informed about a link being created from HDMI or AFE to a CSI-2 TX output, the 'link_setup()' callback is invoked. Make sure to implement proper routing management at link setup time, to route the selected video stream to the desired TX output.

2019-02-18media: adv748x: Store the TX sink in HDMI/AFEJacopo Mondi4-4/+19
Both the AFE and HDMI s_stream routines (adv748x_afe_s_stream() and adv748x_hdmi_s_stream()) have to enable the CSI-2 TX they are streaming video data to. With the introduction of dynamic routing between HDMI and AFE entities to TXA, the video stream sink needs to be set at run time, and not statically selected as the s_stream functions are currently doing. To fix this, store a reference to the active CSI-2 TX sink for both HDMI and AFE sources, and operate on it when starting/stopping the stream.

2019-02-18media: adv748x: Store the source subdevice in TXJacopo Mondi3-4/+12
The power_up_tx() procedure needs to set a few registers conditionally to the selected video source, but it currently checks for the provided tx to be either TXA or TXB. With the introduction of dynamic routing between HDMI and AFE entities to TXA, checking which TX the function is operating on is not meaningful anymore. To fix this, store the subdevice of the source providing video data to the CSI-2 TX in the 'struct adv748x_csi2' representing the TX and check on it.

The driver uses variables to store frame resolutions and to indexing various arrays. These should be unsigned. Signed-off-by: Petr Cvek <petrcvekcz@gmail.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

2019-01-16media: i2c: ov9640: drop soc_camera code and switch to v4l2_asyncPetr Cvek2-23/+55
This patch removes the dependency on an obsoleted soc_camera from ov9640 driver and changes the code to be a standalone v4l2 async subdevice. It also adds GPIO allocations for power and reset signals (as they are not handled by soc_camera now). The values for waiting on GPIOs (reset and power) settling down were taken from the datasheet (> 1 ms after HW/SW reset). The upper limit was chosen as an arbitrary value. Also one occurrence of mdelay() was changed to msleep(). The delays were successfully tested on a real hardware. The patch makes ov9640 sensor again compatible with the pxa_camera driver.

2019-01-16media: soc_camera: ov9640: move ov9640 out of soc_cameraPetr Cvek5-2/+958
Initial part of ov9640 transition from soc_camera subsystem to a standalone v4l2 subdevice. The soc_camera version seems to be used only in Palm Zire72 and in (the future) HTC Magician. On these two devices the support is broken as pxa_camera driver doesn't use soc_camera anymore. The other mentions from git grep are "TODOs" (in board-osk.c) or chip names for unsupported sensors on HW which doesn't use soc_camera at all (irelevant). Copy the driver files from soc_camera and mark the original ones in the Kconfig description as obsoleted. Add config option VIDEO_OV9640 to the build files in drivers/media/i2c.
