2020-02-27media: smiapp: Move definitions under driver directorySakari Ailus
include/media/i2c/smiapp.h was meant to serve systems where the sensor is enumerated through platform data. That's no longer necessary, hopefully not even in out-of-tree use cases.

2020-01-04media: i2c: mt9v032: fix enum mbus codes and frame sizesEugen Hristev
This driver supports both the mt9v032 (color) and the mt9v022 (mono) sensors. Depending on which sensor is used, the format from the sensor is different. The format.code inside the dev struct holds this information. The enum mbus and enum frame sizes need to take into account both type of sensors, not just the color one. To solve this, use the format.code in these functions instead of the hardcoded bayer color format (which is only used for mt9v032).

2020-01-04media: ov5640: Fix check for PLL1 exceeding max allowed rateAdam Ford
The variable _rate is by ov5640_compute_sys_clk() which returns zero if the PLL exceeds 1GHz. Unfortunately, the check to see if the max PLL1 output is checking 'rate' and not '_rate' and 'rate' does not ever appear to be 0. This patch changes the check against the returned value of '_rate' to determine if the PLL1 output exceeds 1GHz.

2020-01-04media: ov5640: Put max framerate into table and simplify checkAdam Ford
Currently the various modes are placed into a table, but when ov5640_find_mode is called, it has to double check whether or not the requested framerate is tolerated by the mode. The determination is based on checking hact, vact, and frame rate. Only 640x480 is allowed at 60fps and QSXGA is limited to 15fps, but as the number of permitted frame rates change, this will begin to add more and more complexity to the check. This patch simplifies the check by adding the max framerate allowed for each mode into the table of modes. It then compares the requested framerate to the max permitted in the mode's table. This reduces the number of comparisions to one down from three at run-time.
