 * struct v4l2_ctrl_av1_film_grain - AV1 Film Grain parameters.
 *
 * Film grain parameters as specified by section 6.8.20 of the AV1 Specification.
 *
 * @flags: see V4L2_AV1_FILM_GRAIN_{}.
 * @cr_mult: represents a multiplier for the cr component used in derivation of
 * the input index to the cr component scaling function.
 * @grain_seed: specifies the starting value for the pseudo-random numbers used
 * during film grain synthesis.
 * @film_grain_params_ref_idx: indicates which reference frame contains the
 * film grain parameters to be used for this frame.
 * @num_y_points: specifies the number of points for the piece-wise linear
 * scaling function of the luma component.
 * @point_y_value: represents the x (luma value) coordinate for the i-th point
 * of the piecewise linear scaling function for luma component. The values are
 * signaled on the scale of 0..255. In case of 10 bit video, these values
 * correspond to luma values divided by 4. In case of 12 bit video, these values
 * correspond to luma values divided by 16.
 * @point_y_scaling:  represents the scaling (output) value for the i-th point
 * of the piecewise linear scaling function for luma component.
 * @num_cb_points: specifies the number of points for the piece-wise linear
 * scaling function of the cb component.

 * piece-wise linear scaling function for cb component. The values are signaled
 * on the scale of 0..255.
 * @point_cb_scaling: represents the scaling (output) value for the i-th point

 * piece-wise linear scaling function for cr component. The values are signaled
 * on the scale of 0..255.
 * @point_cr_scaling:  represents the scaling (output) value for the i-th point
 * of the piecewise linear scaling function for cr component.
 * @grain_scaling_minus_8: represents the shift – 8 applied to the values of the
 * chroma component. The grain_scaling_minus_8 can take values of 0..3 and
 * determines the range and quantization step of the standard deviation of film
 * grain.
 * @ar_coeff_lag: specifies the number of auto-regressive coefficients for luma
 * and chroma.

 * plane.

 * plane.
 * @ar_coeff_shift_minus_6: specifies the range of the auto-regressive
 * coefficients. Values of 0, 1, 2, and 3 correspond to the ranges for
 * auto-regressive coefficients of [-2, 2), [-1, 1), [-0.5, 0.5) and [-0.25,
 * 0.25) respectively.

   Although std_id is 64 bits, there is an issue on PPC32 architecture that
   makes switch(u_int64_t) to break. So, there's a hack on v4l2-common.c rounding
   this value to 32 bits.
   As, currently, the max value is for V4L2_STD_ATSC_16_VSB (30 bits wide),
   it should work fine. However, if needed to add more than two standards,
   v4l2-common.c should be fixed.
