/* Example for an F1C100S kernel/BSP that exposes tcon0 and a DPI panel port.
 * The board routes RGB666 (SoC D2..7, D10..15 and D18..23), HSYNC, VSYNC,
 * DE and DOTCLK to J_LCD. The ILI9488 must also be initialized over its
 * PE7..PE10 control bus by U-Boot or a board-specific panel driver.
 *
 * The porch/clock values below are conservative bring-up values, not a
 * substitute for the exact ER-TFT035IPS-6 order-code datasheet. Validate
 * polarity and timings on the purchased panel before freezing an image.
