+
+### GPIO naming convention:
+
+Meson/Amlogic SoCs use the following GPIO naming:
+- GPIOAO_x: Always-On GPIO bank
+- GPIOX_x: Main GPIO bank X
+- GPIOH_x: Main GPIO bank H  
+- GPIOA_x: Main GPIO bank A
+- GPIOBOOT_x: Boot GPIO bank
+
+Refer to your board's pinout diagram for specific pin locations.
