The target panel is the Winstar WF35-320480UD (480x320, RGB666 18-bit), used on a custom STM32MP151A-based board by Amel s.r.l. MIPI DBI Type C Option 1 requires 9-bit SPI transfers where the MSB encodes the Data/Command flag. Since many SPI controllers do not support 9 bits-per-word natively, a native 9-bit implementation and an 8-bit emulation fallback are both provided. The series is structured as follows: [1/4] Extends the mipi_dbi core with Type C Option 1 transfer support, including 8-bit emulation for controllers that lack native 9-bit SPI capability. [2/4] Adds a rotation field to struct mipi_dbi_dev so that panel drivers can configure the MADCTL register from a device tree property. [3/4] Device tree binding documentation for ILI9488-based panels, with a vendor-specific compatible for the Winstar WF35-320480UD. [4/4] The ILI9488 panel driver itself, with RGB565-to-RGB666 framebuffer conversion, backlight control and rotation support. Tested on an STM32MP151A-based board with SPI and a WF35-320480UD panel.
