Calxeda Highbank Platforms Device Tree Bindings
|
||||
-----------------------------------------------
|
||||
|
||||
Boards with Calxeda Cortex-A9 based Highbank SOC shall have the following
|
||||
properties.
|
||||
|
||||
Required root node properties:
|

* ARM L2 Cache Controller
|
||||
|
||||
ARM cores often have a separate level 2 cache controller. There are various
|
||||
implementations of the L2 cache controller with compatible programming models.
|
||||
The ARM L2 cache representation in the device tree should be done as follows:
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : should be one of:
|
||||
"arm,pl310-cache"
|
||||
"arm,l220-cache"
|
||||
"arm,l210-cache"
|
||||
- cache-unified : Specifies the cache is a unified cache.
|
||||
- cache-level : Should be set to 2 for a level 2 cache.
|
||||
- reg : Physical base address and size of cache controller's memory mapped
|
||||
registers.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- arm,data-latency : Cycles of latency for Data RAM accesses. Specifies 3 cells of
|
||||
read, write and setup latencies. Minimum valid values are 1. Controllers
|
||||
without setup latency control should use a value of 0.
|
||||
- arm,tag-latency : Cycles of latency for Tag RAM accesses. Specifies 3 cells of
|
||||
read, write and setup latencies. Controllers without setup latency control
|
||||
should use 0. Controllers without separate read and write Tag RAM latency
|
||||
values should only use the first cell.
|
||||
- arm,dirty-latency : Cycles of latency for Dirty RAMs. This is a single cell.
|
||||
- arm,filter-ranges : <start length> Starting address and length of window to
|
||||
filter. Addresses in the filter window are directed to the M1 port. Other
|
||||
addresses will go to the M0 port.
|
||||
- interrupts : 1 combined interrupt.
|
||||
|
||||
Example:
|
||||
|
||||
L2: cache-controller {
|
||||
compatible = "arm,pl310-cache";
|
||||
reg = <0xfff12000 0x1000>;
|
||||
arm,data-latency = <1 1 1>;
|
||||
arm,tag-latency = <2 2 2>;
|
||||
arm,filter-latency = <0x80000000 0x8000000>;
|
||||
cache-unified;
|
||||
cache-level = <2>;
|
||||
interrupts = <45>;
|
||||
};
