H A Daspeed-lpc.txt2 Device tree bindings for the Aspeed Low Pin Count (LPC) Bus Controller
5 The LPC bus is a means to bridge a host CPU to a number of low-bandwidth
7 primary use case of the Aspeed LPC controller is as a slave on the bus
11 The LPC controller is represented as a multi-function device to account for the
14 "basically compatible with the [LPC registers from the] popular BMC controller
22 * An LPC Host Controller: Manages LPC functions such as host vs slave mode, the
23 physical properties of some LPC pins, configuration of serial IRQs, and
24 APB-to-LPC bridging amonst other functions.
26 * An LPC Host Interface Controller: Manages functions exposed to the host such
27 as LPC firmware hub cycles, configuration of the LPC-to-AHB mapping, UART
