+This document describes overlays provided in the kernel packages
+For generic Armbian overlays documentation please see
+https://docs.armbian.com/Hardware_Allwinner_overlays/
+
+### Platform:
+
+sun8i-h3 (Allwinner H3)
+
+### Platform details:
+
+Supported pin banks: PA, PC, PD, PG
+
+Both SPI controllers have only one hardware CS,
+so SPI chip select is always set to 0
+
+Using software (GPIO) SPI chip selects is possible, but since
+GPIO pins cannot be changed dynamically due to u-boot limitation,
+this feature is not used in provided overlays.
+
+### Provided overlays:
+
+- analog-codec
+- cir
+- i2c0
+- i2c1
+- i2c2
+- i2c-ds1307
+- spi-jedec-nor
+- spi-mcp2515
+- spi-spidev
+- uart1
+- uart2
+- uart3
+- usbhost0
+- usbhost2
+- usbhost3
+- w1-gpio
