2023-07-19media: aspeed: Fix memory overwrite if timing is 1600x900Jammy Huang
When capturing 1600x900, system could crash when system memory usage is tight. The way to reproduce this issue: 1. Use 1600x900 to display on host 2. Mount ISO through 'Virtual media' on OpenBMC's web 3. Run script as below on host to do sha continuously #!/bin/bash while [ [1] ]; do find /media -type f -printf '"%h/%f"\n' | xargs sha256sum done 4. Open KVM on OpenBMC's web The size of macro block captured is 8x8. Therefore, we should make sure the height of src-buf is 8 aligned to fix this issue.

2023-07-19media: ds90ub9xx: switch three more drivers back to use struct ↵Uwe Kleine-König
i2c_driver::probe() struct i2c_driver::probe_new() is about to go away. Since I converted all drivers below drivers/media use struct i2c_driver::probe, three more drivers were added in the following commits that use .probe_new(): commit 6363db1c9d45 ("media: i2c: add DS90UB953 driver") commit c158d0d4ff15 ("media: i2c: add DS90UB913 driver") commit afe267f2d368 ("media: i2c: add DS90UB960 driver") Switch these driver to use the probe callback.

2023-07-19media: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

The supported ad5820 and ad5821 VCMs both use a single 16 bit register which is written by sending 2 bytes with the data directly after sending the i2c-client address. The ad5823 OTOH has a more typical i2c / smbus device setup with multiple 8 bit registers where the first byte send after the i2c-client address is the register address and the actual data only starts from the second byte after the i2c-client address. The ad5823 i2c_ and of_device_id-s was added at the same time as the ad5821 ids with as rationale: """ Some camera modules also refer that AD5823 is a replacement of AD5820: https://download.kamami.com/p564094-OV8865_DS.pdf """ The AD5823 may be an electrical and functional replacement of the AD5820, but from a software pov it is not compatible at all and it is going to need its own driver, drop its id from the ad5820 driver.

The ov13b10 need be connected to a CIO2 or IPU device by bridge, sometimes the bridge driver was not probed before ov13b10 driver, then the absence of the fwnode endpoint for this device is expected, so driver return -EPROBE_DEFER in this case to let the probe occur after bridge driver.

2023-07-14media: ov5640: fix low resolution image abnormal issueGuoniu.zhou
OV5640 will output abnormal image data when work at low resolution (320x240, 176x144 and 160x120) after switching from high resolution, such as 1080P, the time interval between high and low switching must be less than 1000ms in order to OV5640 don't enter suspend state during the time. The reason is by 0x3824 value don't restore to initialize value when do resolution switching. In high resolution setting array, 0x3824 is set to 0x04, but low resolution setting array remove 0x3824 in commit db15c1957a2d ("media: ov5640: Remove duplicated mode settings"). So when do resolution switching from high to low, such as 1080P to 320x240, and the time interval is less than auto suspend delay time which means global initialize setting array will not be loaded, the output image data are abnormal. Hence move 0x3824 from ov5640_init_setting[] table to ov5640_setting_low_res[] table and also move 0x4407 0x460b, 0x460c to avoid same issue.

The HTS value cannot be directly compared to the sensor's output size. It needs to be converted to an absolute time unit. Additionally, the hblank value need to be modified as it was previous invalid.
