It belongs to the first Mediatek's camera driver series based on V4L2 and media controller framework. I posted the main part of the seninf driver as RFC to discuss first and would like some review comments on the overall structure of the driver. The driver is implemented with V4L2 framework. 1. Register as a V4L2 sub-device. 2. Only one entity with sink pads linked to camera sensors for choosing desired camera sensor by setup link and with source pads linked to cam-io for routing different types of decoded packet datas to PASS1 driver to generate sensor image frame and meta-data. The overall file structure of the seninf driver is as following: * mtk_seninf.c: Implement software and HW control flow of seninf driver. * seninf_drv_def.h: Define data structure and enumeration. * seninf_reg.h: Define HW register R/W macros and HW register names.
