ARM: dts: cm-t335: add initial support
Add basic support for CompuLab cm-t335 module based on AM335X SoC. CM-T335 is a tiny computer-on-module (CoM) / system-on-module (SoM) The module is built around the Texas Instruments Sitara AM3352/4 system-on-chip. The CPU is supplemented with up-to 512MB DDR3 and up-to 1GB of on-board NAND storage, WiFi connected to SPI, Bluetooth, Analog audio, Gigabit Ethernet, CAN bus. Current patch adds support: UART0 and GPIO LED Detailed description can be found at the module site: http://www.compulab.co.il/products/computer-on-modules/cm-t335/ Signed-off-by: Ilya Ledvich <ilya@compulab.co.il> [uri.mashiach@compulab.co.il: the default RAM amount reduced to 128MB to support also the minimal module configuration] Signed-off-by: Uri Mashiach <uri.mashiach@compulab.co.il> Acked-by: Igor Grinberg <grinberg@compulab.co.il> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
