Hi,

Can anyone explain the field .min_afps in the following struct

static struct vvcam_mode_info_s pov2775_mode_info[] = {
	{
		.index          = 0,
		.size           = {
			.bounds_width  = 1920,
			.bounds_height = 1080,
			.top           = 0,
			.left          = 0,
			.width         = 1920,
			.height        = 1080,
		},
		.hdr_mode       = SENSOR_MODE_LINEAR,
		.bit_width      = 12,
		.data_compress  = {
			.enable = 0,
		},
		.bayer_pattern = BAYER_BGGR,
		.ae_info = {
			.def_frm_len_lines     = 0x466,
			.curr_frm_len_lines    = 0x466,
			.one_line_exp_time_ns  = 29625,

			.max_integration_line  = 0x466 - 4,
			.min_integration_line  = 1,

			.max_again             = 8 * 1024,
			.min_again             = 2 * 1024,
			.max_dgain             = 4 * 1024,
			.min_dgain             = 1.5 * 1024,
			.gain_step             = 4,
			.start_exposure        = 3 * 400 * 1024,
			.cur_fps               = 30 * 1024,
			.max_fps               = 30 * 1024,
			.min_fps               = 5 * 1024,
			.min_afps              = 5 * 1024,
			.int_update_delay_frm  = 1,
			.gain_update_delay_frm = 1,
		},
		.mipi_info = {
			.mipi_lane = 4,
		},
		.preg_data      = ov2775_init_setting_1080p,
		.reg_data_count = ARRAY_SIZE(ov2775_init_setting_1080p),
	},
