[PATCH v2 1/2] ARM: dts: imx7d: cl-som-imx7: add basic module support

Ilya Ledvich
2015-12-22T08:15:19Z

CL-SOM-iMX7 is a miniature System-on-Module (SoM) based on
Freescale i.MX7 System-on-Chip family.

http://www.compulab.co.il/products/computer-on-modules/cl-som-imx7-freescale-i-mx-7-system-on-module/

Add basic DT support for standalone module (without a carrier board):

* Memory configuration
* eMMC
* 2x Gigabit Ethernet ports (FEC1 and FEC2)
* I2C2 bus
* EEPROM
* PCA9555 GPIO extender
* PMIC
* UART1
* USB OTG port

v2: use generic node name for pmic (Thanks Rob)
move board description out of fsl.txt (Shawn)
use GPL/X11 dual licence for newly added dts files (Shawn)
discard one level of container node (Shawn)
squash several patches into one patch (Shawn)
