Detailed Description

Compact video-mode timing block (HSA/HBP/HACT/HFP + VSA/VBP/VACT/VFP).

Lighter-weight cousin of ra8_mipi_dsi_video_cfg_t for callers that just need to load timing numbers and accept the driver defaults for sync polarity, pixel format (RGB888) and HSA/HBP/HFP-no-LP behaviour. Maps onto VMVSSETR / VMVPSETR / VMHSSETR / VMHPSETR per HUM Ch 65 "MIPI DSI Host" pp 3839-3934.

Invariant

All eight counts fit into the bit widths of their target registers (sync = 12 bits, porch = 13 bits, active = 15 bits).

const ra8_mipi_dsi_video_timing_t t = {
  .horizontal_sync   = 12,  .horizontal_back_porch = 64,
  .horizontal_active = 1024, .horizontal_front_porch = 32,
  .vertical_sync     = 4,   .vertical_back_porch    = 8,
  .vertical_active   = 600, .vertical_front_porch   = 6,
};
(void)ra8_mipi_dsi_set_video_timing(&t);
