ARM: dts: rockchip: Add support for PCM-947 carrier board
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 Signed-off-by: Wadim Egorov <w.egorov@phytec.de> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
