[PATCH v2 0/3] ARM64: dts: meson-gxl: Add support for Libre Technology CC board

[Jerome Brunet]

This patchset adds support for the CC board from Shenzhen Libre Technology

This board derives from the s905x p212 reference design. it provides:
* Ethernet using the internal PHY
* 4 USB ports
* Composite Audio/Video jack
* HDMI
* IR

It also provides 2 Headers (40 and 8 pins) for GPIOs and the following
functions:
* 2 i2c busses
* SPI
* SDIO
* I2S 8ch output
* PWMs
* UART with HW flow control
* PCM
* 2 ADC Channels
