+description: >
+  E-paper display panels driven by the tuanpmt/esp_epaper ESP-IDF component
+  (SSD1680/1681 BW, GDEY0154D67 and ACeP/BWRY color controllers). The node must
+  be a child of an SPI controller: the display shares the parent's SPI host,
+  clock and MOSI pins, and manages its DC/RESET/BUSY/CS pins itself via the
+  component. Only 1bpp black/white panels are supported by the kernel display
+  bridge (DISPLAY_COLOR_FORMAT_MONOCHROME); color panels fail to start.

+      Full is the safest default; fast and partial refresh quickly but ghost.
+      Values above 2 are rejected at driver start.

+      Fixed display rotation applied at start. 0 = 0 degrees, 1 = 90 degrees,
+      2 = 180 degrees, 3 = 270 degrees counter-clockwise (matching
+      LV_DISPLAY_ROTATION_*). The kernel bridge reports the rotated resolution,
+      so LVGL renders in rotated space and the driver rotates the 1bpp frame
+      back to the panel's native layout before updating. Not changeable at
+      runtime.
