Hello, Quite a few drivers for I2C camera sensors and video encoders are bit-rotting in drivers/media/i2c/. In particular, seven drivers have been merged requiring platform data, never converted to DT, and have either never had a user in the mainline kernel (ad9389b, mt9m032, mt9t001 and sr030pc30) or have no user anymore after board files have been dropped (m5mols, s5k6aa and vs6624). Another driver, the noon010pc30, also falls in the same category, but the device is listed in a device tree file in mainline. There is however no DT binding, and no DT support in the driver. Unless someone is interested in converting those drivers to DT (and maintaining them !), these are more than 10k lines of dead code. This RFC simply drops them. Seven more drivers (ak881x, mt9t112, noon010pc30, rj45n1cb0c, ths7303, tw9910 and wm8775) are used in arch/sh/ board files only, for boards that will likely never be converted to DT. As arch/sh/ seems to be headed for either a DT conversion or a complete drop, those drivers may also be removed in the future.
