This is a single-patch series that fixes the display mode definition in the ili9486 tiny DRM driver. The driver currently uses `DRM_SIMPLE_MODE()` which sets a dummy pixel clock of 1 kHz, resulting in a calculated vrefresh of approximately 0.006 Hz. The patch replaces it with `DRM_MODE_INIT(30, ...)` which computes a pixel clock that yields a 30 Hz vrefresh value.

The commit message is well-written and provides concrete evidence of the problem: Weston logs abnormal repaint delay warnings, and GTK4 clients under wlroots-based compositors fail to visually update because they use the reported refresh rate for scheduling. The fix is minimal and appropriate — a single macro substitution with no behavioral side effects beyond the mode metadata. The pixel clock calculation (`480 * 320 * 30 / 1000 = 4608 kHz`) is correct and produces the intended 30 Hz vrefresh. No issues found.
