+Subject: [PATCH] ARM: dts: imx: add support for Gaben FlexiSBC
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+!!! TODO !!!
+
+Gaben FlexiSBC is custom carrier board utilizing Toradex Apalis i.MX6
+family of modules. It's being developed, sold and supported by gaben.cz.
+
+Features:
+
+* 1x ADV7180
+* 1x CAN (terminator)
+* 1x galvanically isolated RS485/RS232 (terminator, protection diodes)
+* 1x RS232 with DB9 connector with all signals (missing RI)
+* 4x digital inputs, optically isolated, surge protection
+* 4x digital outputs, using Omron G5V2 relays with max. 2A switching current
+* microSD card slot, 4-bit SDIO, GPIO for card detect
+* LVDS (3x data and clock pairs), usually not populated
+* MCP9800 thermometer on I2C1
+* 4x buttons, RGB LED
+* Secondary watchdog using external MCU
+* Dog128 LCD connected to SPI1 with PWM backlight
+* 4x extension slots using miniPCIe connector format:
+ - GSM&GPS, including SIM card slot for standard sized SIMs
+ - user controllable power source VCC-GSM (GPIO expander)
+ - UART3 signals shared with RFID (jumper select)
+ - PCIe standard slot usually used for WiFi cards
+ - 3x Rx,Tx,CLK diff pairs, WAKE, RESET (PRsT), USB, I2C signals
+ - user controllable power source VCC-PCIE (GPIO expander)
+ - CUSTOM with CAN2, UART4, SPI2, USB, I2C3, 3x GPIO
+ - user controllable power source VCC-CUSTOM (GPIO expander)
+ - RFID with USB, UART3, and WAKEUP/RESET GPIOs
+ - UART3 signals shared with GSM&GPS (jumper select)
