Where, the min_gain_val, max_gain_val, step_gain_val are part of the cameras' DTSI (tegra186-tx2-spiri-camera.dtsi) fixed parameters * <a href="https://files.niemo.de/aptina_pdfs/MT9M021-M031_Developer_Guide.pdf">MT9M021 Developer Guide</a>
as per the datasheet. The step_gain_val consists of the steps (1/32 for the register) scaled to a value that makes this fraction become an significant
in integer.
Where, the `min_gain_val, max_gain_val, step_gain_val` are part of the cameras' DTSI (tegra186-tx2-spiri-camera.dtsi) fixed parameters
as per the datasheet. The `gain` consists on the steps (1x + n * 1/32 for the register) scaled to a value that represents this fraction in an integer value for the gain register.
