STM32U5G9 – 90° rotated display without a second framebuffer (LTDC / GFXMMU / GPU2D)

Hi,We’re using an STM32U5G9 with a MIPI DSI panel (driven by the LTDC through the DSI host). The panel is 800×600 and scans in landscape, but it’s mounted rotated, so the user sees a 600×800 portrait image. The panel controller can’t swap its scan di
