+This document describes overlays provided in the kernel packages
+For generic Armbian overlays documentation please see
+https://docs.armbian.com/User-Guide_Allwinner_overlays/
+
+### Platform:
+
+sun8i-h3 (Allwinner H3)
+
+### Platform details:
+
+Supported pin banks: PA, PC, PD, PG
+
+Both SPI controllers have only one hardware CS pin exposed,
+adding fixed software (GPIO) chip selects is possible with a separate overlay
+
+### Provided overlays:
+
+- analog-codec
+- cir
+- i2c0
+- i2c1
+- i2c2
+- pps-gpio
+- pwm
+- spdif-out
+- spi-add-cs1
+- spi-jedec-nor
+- spi-spidev
+- uart1
+- uart2
+- uart3
+- usbhost0
+- usbhost2
+- usbhost3
+- w1-gpio
+
+### Overlay details:
+
+### analog-codec
+
+Activates SoC analog codec driver that provides Line Out and Mic In
+functionality
+
+### cir
+
+Activates CIR (Infrared remote) receiver
+
+CIR pin: PL11
+
+### i2c0
+
+Activates TWI/I2C bus 0
+
+I2C0 pins (SCL, SDA): PA11, PA12
+
+### i2c1
+
+Activates TWI/I2C bus 1
+
+I2C1 pins (SCL, SDA): PA18, PA19
+
+### i2c2
+
+Activates TWI/I2C bus 2
+
+I2C2 pins (SCL, SDA): PE12, PE13
+
+On most board this bus is wired to Camera (CSI) socket
+
+### pps-gpio
+
+Activates pulse-per-second GPIO client
+
+Parameters:
+
+param_pps_pin (pin)
+	Pin PPS source is connected to
+	Optional
+	Default: PD14
+
+param_pps_falling_edge (bool)
+	Assert by falling edge
+	Optional
+	Default: 0
+	When set (to 1), assert is indicated by a falling edge
+		(instead of by a rising edge)
+
+### pwm
+
+Activates hardware PWM controller
+
+PWM pin: PA5
+
+Pin PA5 is used as UART0 RX by default, so if this overlay is activated,
+UART0 and kernel console on ttyS0 will be disabled
+
+### spdif-out
+
+Activates SPDIF/Toslink audio output
+
+SPDIF pin: PA17
+
+### spi-add-cs1
+
+Adds support for using SPI chip select 1 with GPIO for both SPI controllers
+Respective GPIO will be claimed only if controller is enabled by another
+overlay
+This overlay is required for using chip select 1 with other SPI overlays
+Due to the u-boot limitations CS1 pin can't be customized by a parameter, but
+it can be changed by using an edited copy of this overlay
+A total of 4 chip selects can be used with custom overlays (1 HW + 3 GPIO)
+
+SPI 0 pins (CS1): PA21
+SPI 1 pins (CS1): PA10
+
+### spi-jedec-nor
+
+Activates MTD support for JEDEC compatible SPI NOR flash chips on SPI bus
+supported by the kernel SPI NOR driver
+
+SPI 0 pins (MOSI, MISO, SCK, CS): PC0, PC1, PC2, PC3
+SPI 1 pins (MOSI, MISO, SCK, CS): PA15, PA16, PA14, PA13
+
+Parameters:

+
+param_spinor_spi_cs (int)

+param_spinor_max_freq (int)
+	Maximum SPI frequency
+	Optional
+	Default: 1000000
+	Range: 3000 - 100000000

+Activates SPIdev device node (/dev/spidevX.Y) for userspace SPI access,
+where X is the bus number and Y is the CS number
+
+SPI 0 pins (MOSI, MISO, SCK, CS): PC0, PC1, PC2, PC3
+SPI 1 pins (MOSI, MISO, SCK, CS): PA15, PA16, PA14, PA13

+	Set to 1 to enable
+
+### uart2
+
+Activates serial port 2 (/dev/ttyS2)
+
+UART 2 pins (TX, RX, RTS, CTS): PA0, PA1, PA2, PA3
+
+Parameters:
+
+param_uart2_rtscts (bool)

+	Data pin for 1-Wire master
+	Optional
+	Default: PD14
+
+param_w1_pin_int_pullup (bool)

+	Optional
+	Default: 0
+	Set to 1 to enable the pull-up
+	This option should not be used with multiple devices, parasite power setup
+		or long wires -	please use external pull-up resistor instead
