TI Keystone DSP Memory Mapping Device ===================================== Binding status: Unstable - ABI compatibility may be broken in the future The Keystone DSP Memory Mapping Device is a device node used to represent the memory regions that can be mapped into userspace for providing direct user-mode access to regions for the purposes of shared memory communication with the DSP remote processor devices on the SoC. It can also be used for supporting user-space based loading of the DSP remoteproc devices. Required properties: -------------------- - compatible : Should be "ti,keystone-dsp-mem" - reg : An array of memory regions, each region represented by a tuple of the region's start address and the size of the region. Example: -------- /* K2HK EVM */ soc { mpm_mem: dspmem { compatible = "ti,keystone-dsp-mem"; reg = <0x0c000000 0x00600000>, /* MSMC Memory */ <0xa0000000 0x20000000>; /* DDR Memory */ }; };
