2025-05-05media: atomisp: Remove atomisp-mt9m114 driverHans de Goede4-3393/+0
The "media: atomisp: Add support for sensors with a separate ISP v4l2_subdev" combined with some pending drivers/media/i2c/mt9m114.c changes makes the atomisp work nicely with the standard V4L2 mt9m114.c driver, avoiding the need for the atomisp specific atomisp-mt9m114 driver. The normal driver actually works better since the atomisp-mt9m114 driver does not have working exposure control, leading to a much too dark image. Remove the no longer necessary atomisp-mt9m114 driver.

2025-05-05media: atomisp: Add support for sensors with a separate ISP v4l2_subdevHans de Goede4-11/+65
Some sensors have an ISP inside the sensor which the sensor driver models as a separate v4l2-subdev, like the mt9m114 sensor-driver does. Since the atomisp driver emulates a standard /dev/video# v4l2-device without requiring the application to be aware of media-controller centric /dev/video# devices this requires some special handling in the driver. Add support for this setup to the atomisp driver.

2025-05-05media: atomisp: Avoid deadlock with sensor subdevs with state_lock setHans de Goede1-2/+9
When a (sensor) v4l2_subdev has its state_lock member set to non NULL, then all v4l2_subdev_state-s for the sensor share the same lock. atomisp_init_sensor() calls v4l2_subdev_lock_and_get_active_state() and then later on also tries to lock a separate v4l2_subdev_state used for try calls (rather then changing the active state), while still holding the active state lock. Since this try v4l2_subdev_state shares a lock with the active state this results in a deadlock. Skip locking try_sd_state when sensor->state_lock is set to avoid this.

2025-05-05media: atomisp: Avoid picking too big sensor resolutionHans de Goede1-3/+8
atomisp_try_fmt() is limiting the width of the requested resolution to 1920 before calling the sensor's try_fmt() method. But it is not limiting the height. In case of the old mode-list based t4ka3 driver which has a mode list of: 736x496 896x736 1936x1096 3280x2464 This results in 3280x2464 being selected when try_fmt is called with a requested resolution of 3280x2464, which is not supported because its width > 1920 . Fix this by also limiting the height when in preview mode.

2025-05-05media: atomisp: gmin: Remove GPIO driven regulator supportHans de Goede1-69/+0
The GMIN code has support for sensors using external regulators enabled by GPIOS, rather then using regulators build into the PMIC. With the exception of the Trekstor ST70408-4 (1) tablet there are no known devices which actually use external regulators for the sensors and the code for this is using deprecated old style GPIO numbers support for which is going away. Remove the GPIO driven regulator support so that the gmin code no longer depends on deprecated GPIO APIs. 1) The GMIN support itself is also deprecated and all sensor drivers still using it are being moved over to use ACPI + runtime-pm and the ST70408-4 shipped with Android as factory OS and thus will have broken ACPI tables for the sensors, so like other Android factory OS tablets it will need a bespoke solution anyways.

The VIDIOC_ENUM_FRAMESIZES ioctl should return all frame sizes (i.e. width and height in pixels) that the device supports for the given pixel format. It doesn't make a lot of sense to return the frame-sizes in a stepwise manner, which is used to enforce hardware alignments requirements for CAPTURE buffers, for coded formats. Instead, applications should receive an indication, about the maximum supported frame size for that hardware decoder, via a continuous frame-size enumeration.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver updates from Greg KH: "Here is the big set of staging driver changes for 6.13-rc1. Lots of changes this merge cycle, drivers removed and drivers added. Highlights include: - removals of the following staging drivers due to no forward progress and no one having either the hardware or the time/energy to deal with them anymore: - fieldbus - gdm724x - olpc_dcon - rtl8712 - rts5208 - vt6655 - vt6656 If anyone has this hardware and wants to work on the drivers, it can be an easy revert to get them back. - addition of the gpib driver subsystem. Lots of drivers for really old and semi-old interfaces to lab equipments. We expect lots of churn in these drivers as they get cleaned up to "working" order. These were added at the request of a user and the maintainer/author of them is helping out with the effort - loads and loads of tiny coding style cleanups for almost all staging drivers. Too many to list, see the shortlog for details. All of these have been in linux-next for a very long time with no reported issues" * tag 'staging-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (216 commits) Staging: gpib: gpib_os.c - Remove unnecessary OOM message staging: gpib: avoid unintended sign extension staging: vchiq_debugfs: Use forward declarations staging: vchiq_core: Rectify header include for vchiq_dump_state() staging: vc04_services: Cleanup TODO entry staging: most: Remove TODO contact information staging: rtl8723bs: Remove TODO contact information staging: sm750fb: Remove TODO contact information staging: iio: Remove TODO file staging: greybus: uart: Fix atomicity violation in get_serial_info() staging: rtl8723bs: Remove unused function Efuse_GetCurrentSize staging: rtl8723bs: Remove unused function efuse_WordEnableDataRead staging: rtl8723bs: Remove function hal_EfusePgPacketWrite1ByteHeader staging: rtl8723bs: Remove function hal_EfusePgPacketWrite2ByteHeader staging: rtl8723bs: Remove unused function hal_EfusePgCheckAvailableAddr staging: rtl8723bs: Remove unused function hal_EfuseConstructPGPkt staging: rtl8723bs: Remove unused function hal_EfusePartialWriteCheck staging: rtl8723bs: Remove unused function hal_EfusePgPacketWriteHeader staging: rtl8723bs: Remove unused function hal_EfusePgPacketWriteData staging: rtl8723bs: Remove unused function Hal_EfusePgPacketWrite_BT ...

2024-11-07media: atomisp: Add check for rgby_data memory allocation failureLi Huafei1-0/+2
In ia_css_3a_statistics_allocate(), there is no check on the allocation result of the rgby_data memory. If rgby_data is not successfully allocated, it may trigger the assert(host_stats->rgby_data) assertion in ia_css_s3a_hmem_decode(). Adding a check to fix this potential issue.

2024-11-07media: atomisp: remove redundant re-checking of errColin Ian King1-3/+0
The check to see if err is non-zero is always false because err has been previously checked on whenever err has been assigned in previous code paths. The check is redundant and can be removed.
