Move all patch that got merged upstream from pending to backport and add related tag. This is to make it easier to update to kernel 6.12. Patch 680 required some special care as the upstream version had to be split in a series of 6 patch. Referesh all affected patch.

+description: |-
|
|
+ The Sony IMX500 is a stacked 1/2.3-inch CMOS digital image sensor and inbuilt
|
|
+ AI processor with an active array CNN (Convolutional Neural Network) inference
|
|
+ engine. The native sensor size is 4056H x 3040V, and the module also contains
|
|
+ an in-built ISP for the CNN. The module is programmable through an I2C
|
|
+ interface with firmware and neural network uploads being made over SPI. The
|
|
+ default I2C address is 0x1A, with an address of 0x10 being selectable via
|
|
+ SLASEL. The module also has a second I2C interface available with a fixed
|
|
+ address of 0x36. Image data is sent through MIPI CSI-2, which is configured
|
|
+ as either 2 or 4 data lanes.
