+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:
+
+rockchip (Rockchip)
+
+### Provided overlays:
+
+- i2c7, i2c8, pcie-gen2, spi-spidev, uart4, w1-gpio
+
+### Overlay details:
+
+### i2c7
+
+Activates TWI/I2C bus 7
+
+I2C7 pins (DVP) (SCL, SDA): GPIO2-B0, GPIO2-A7
+
+### i2c8
+
+Activates TWI/I2C bus 8
+
+I2C8 pins (pi-conn) (pi-conn) (SCL, SDA): GPIO1-C5, GPIO1-C4
+
+### pcie-gen2
+
+Enables PCIe Gen2 link speed on RK3399.
+WARNING! Not officially supported by Rockchip!!!
+
+### 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): GPIO3_A5, GPIO3_A4, GPIO3_A6, GPIO3_A7
+SPI 1 pins (MOSI, MISO, SCK, CS): GPIO1_A7, GPIO1_B0, GPIO1_B1, GPIO1_B2
+SPI 2 pins (MOSI, MISO, SCK, CS): GPIO1_C0, GPIO1_B7, GPIO1_C1, GPIO1_C2
+SPI 3 pins (MOSI, MISO, SCK, CS): GPIO2_B2, GPIO2_B1, GPIO2_B3, GPIO2_B4
+
+Parameters:
+
+param_spinor_spi_bus (int)
+ SPI bus to activate SPI NOR flash support on
+ Required
+ Supported values: 0, 1, 2
+
+param_spinor_max_freq (int)
+ Maximum SPI frequency
+ Optional
+ Default: 1000000
+ Range: 3000 - 100000000
+
+### spi-spidev
+
+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): GPIO3_A5, GPIO3_A4, GPIO3_A6, GPIO3_A7
+SPI 1 pins (MOSI, MISO, SCK, CS): GPIO1_A7, GPIO1_B0, GPIO1_B1, GPIO1_B2
+SPI 2 pins (MOSI, MISO, SCK, CS): GPIO1_C0, GPIO1_B7, GPIO1_C1, GPIO1_C2
+SPI 3 pins (MOSI, MISO, SCK, CS): GPIO2_B2, GPIO2_B1, GPIO2_B3, GPIO2_B4
+
+Parameters:
+
+param_spidev_spi_bus (int)
+ SPI bus to activate SPIdev support on
+ Required
+ Supported values: 0, 1
+
+param_spidev_spi_cs (int)
+ SPI chip select number
+ Optional
+ Default: 0
+ Supported values: 0, 1
+ Using chip select 1 requires using "spi-add-cs1" overlay
+
+param_spidev_max_freq (int)
+ Maximum SPIdev frequency
+ Optional
+ Default: 1000000
+ Range: 3000 - 100000000
+
+### uart4
+
+Activates UART4
+
+UART4 pins (RX, TX): GPIO1_A7, GPIO1_B0
+
+Notice: UART4 cannot be activated together with SPI1 - they share the sam pins.
+Enabling this overlay disables SPI1.
+
+### w1-gpio
+
+Activates 1-Wire GPIO master
+Requires an external pull-up resistor on the data pin
+or enabling the internal pull-up
+
+Parameters:
+
+param_w1_pin (pin)
+ Data pin for 1-Wire master
+ Optional
+ Default: PD14
+
