-/*! @file ai2c_plat.c
-
- @brief Linux driver implementation of I2C using the ACP I2C
- features upon an LSI development board (San Antonio,
- Mission, El Paso, ...)
-
- @details Command line module parameters (with defaults) include,
- int ai2c_trace_level = (AI2C_MSG_INFO | AI2C_MSG_ERROR);
- int ai2c_chip_ver = -1;
- //Optional: Needed to figure out memory map, etc.
- //Can verify against value from 0xa.0x10.0x2c
- //Values; 0=X1_REL1
- // 1=X1_REL2+
- // 7=X7_REL1+
-
- @details Several items contained in the 'i2c' section of the '.dts'
- are used to configure this module including the addresses of
- the memory partition, IRQ number, number of DMEs to use (when
- we want to override the inferences based on the chipType), etc.
