If NO_DMA=y: ERROR: "dma_free_coherent" [drivers/staging/most/mostcore/mostcore.ko] undefined! ERROR: "dma_alloc_coherent" [drivers/staging/most/mostcore/mostcore.ko] undefined! As all MOST sub drivers use DMA functionality, add a dependency on HAS_DMA to MOSTCORE, and to MOST, which selects MOSTCORE.

2015-07-24Staging: most: add MOST driver's core moduleChristian Gromm
This patch adds the core module of the MOST driver to the kernel's driver staging area. This module is part of the MOST driver and handles the configuration interface in sysfs, the buffer management and the data routing. MOST defines the protocol, hardware and software layers necessary to allow for the efficient and low-cost transport of control, real-time and packet data using a single medium (physical layer). Media currently in use are fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST also supports various speed grades up to 150 Mbps. For more information on MOST, visit the MOST Cooperation website: www.mostcooperation.com. Cars continue to evolve into sophisticated consumer electronics platforms, increasing the demand for reliable and simple solutions to support audio, video and data communications. MOST can be used to connect multiple consumer devices via optical or electrical physical layers directly to one another or in a network configuration. As a synchronous network, MOST provides excellent Quality of Service and seamless connectivity for audio/video streaming. Therefore, the driver perfectly fits to the mission of Automotive Grade Linux to create open source software solutions for automotive applications. The driver consists basically of three layers. The hardware layer, the core layer and the application layer. The core layer consists of the core module only. This module handles the communication flow through all three layers, the configuration of the driver, the configuration interface representation in sysfs, and the buffer management. For each of the other two layers a selection of modules is provided. These modules can arbitrarily be combined to meet the needs of the desired system architecture. A module of the hardware layer is referred to as an HDM (hardware dependent module). Each module of this layer handles exactly one of the peripheral interfaces of a network interface controller (e.g. USB, MediaLB, I2C). A module of the application layer is referred to as an AIM (application interfacing module). The modules of this layer give access to MOST via one the following ways: character devices, ALSA, Networking or V4L2. To physically access MOST, an Intelligent Network Interface Controller (INIC) is needed.
