ARM: dts: am57xx: cl-som-am57x: add basic module support
Add support for CompuLab CM-SOM-AM57X board. CL-SOM-AM57x is a miniature System-on-Module (SoM) based on TI Sitara AM57x ARM Cortex-A15 System-on-Chip family. https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/ Add basic DT support for standalone module (without a carrier board): * Memory configuration * Heartbeat led * I2C1 and I2C4 * PMIC * SATA Signed-off-by: Dmitry Lifshitz <lifshitz@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>
