Add basic support for the PCM-947 carrier board, a RK3288 based development
board made by PHYTEC. This board works in a combination with
the phyCORE-RK3288 System on Module.
Following interfaces and devices are available on the PCM-947 carrier board:
- 2x UART
- micro SDMMC
- USB host and USB otg
- USB 3503 HSIC hub
- Ethernet
- 2nd alternative KSZ9031 ethernet phy
- Display connectors: PHYTEC LVDS, DDG LVDS, parallel signals, HDMI
- Parallel Camera CIF
- SGTL5000-32QFN audio codec
- 4x LEDs connected via PCA9533
- 2 user buttons
- Expansion connectors for WiFi and other modules
- RTC RV-4162-C7
- Resistive touch STMPE811
- EEPROM M24C32
