* Device tree bindings for Aspeed SoC Display Controller (GFX)
|
||||
|
||||
The Aspeed SoC Display Controller primarily does as its name suggests, but also
|
||||
participates in pinmux requests on the g5 SoCs. It is therefore considered a
|
||||
syscon device.
|
||||
|
||||
Required properties:
|
||||
- compatible: "aspeed,ast2500-gfx", "syscon"
|
||||
- reg: contains offset/length value of the GFX memory
|
||||
region.
|
||||
|
||||
Example:
|
||||
|
||||
gfx: display@1e6e6000 {
|
||||
compatible = "aspeed,ast2500-gfx", "syscon";
|
||||
reg = <0x1e6e6000 0x1000>;

======================================================================
|
||||
Device tree bindings for the Aspeed Low Pin Count (LPC) Bus Controller
|
||||
======================================================================
|
||||
|
||||
The LPC bus is a means to bridge a host CPU to a number of low-bandwidth
|
||||
peripheral devices, replacing the use of the ISA bus in the age of PCI[0]. The
|
||||
primary use case of the Aspeed LPC controller is as a slave on the bus
|
||||
(typically in a Baseboard Management Controller SoC), but under certain
|
||||
conditions it can also take the role of bus master.
|
||||
|
||||
The LPC controller is represented as a multi-function device to account for the
|
||||
mix of functionality it provides. The principle split is between the register
|
||||
layout at the start of the I/O space which is, to quote the Aspeed datasheet,
|
||||
"basically compatible with the [LPC registers from the] popular BMC controller
|
||||
H8S/2168[1]", and everything else, where everything else is an eclectic
|
||||
collection of functions with a esoteric register layout. "Everything else",
|
||||
here labeled the "host" portion of the controller, includes, but is not limited
|
||||
to:
|
||||
|
||||
* An IPMI Block Transfer[2] Controller
|
||||
|
||||
* An LPC Host Controller: Manages LPC functions such as host vs slave mode, the
|
||||
physical properties of some LPC pins, configuration of serial IRQs, and
|
||||
APB-to-LPC bridging amonst other functions.
|
||||
|
||||
* An LPC Host Interface Controller: Manages functions exposed to the host such
|
||||
as LPC firmware hub cycles, configuration of the LPC-to-AHB mapping, UART
|
||||
management and bus snoop configuration.
|
||||
|
||||
* A set of SuperIO[3] scratch registers: Enables implementation of e.g. custom
|
||||
hardware management protocols for handover between the host and baseboard
|
||||
management controller.
|
||||
|
||||
Additionally the state of the LPC controller influences the pinmux
|
||||
configuration, therefore the host portion of the controller is exposed as a
|
||||
syscon as a means to arbitrate access.
