== Introduction==
LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
that can be shared by multiple clients. Clients here are different cores in the
SOC, the idea is to minimize the local caches at the clients and migrate to
common pool of memory. Cache memory is divided into partitions called slices
which are assigned to clients. Clients can query the slice details, activate
and deactivate them.
Properties:
- compatible:
Usage: required
Value type: <string>
Definition: must be "qcom,sdm845-llcc"
- reg:

Increasing this value would slow down the mdp processing

Decreasing this value can speed up the mdp processing,
but this can also impact power consumption.
As a rule this time should not be higher than the time

* Actions Semi Owl SoCs DMA controller
This binding follows the generic DMA bindings defined in dma.txt.
Required properties:
- compatible: Should be "actions,s900-dma".
- reg: Should contain DMA registers location and length.
- interrupts: Should contain 4 interrupts shared by all channel.
- #dma-cells: Must be <1>. Used to represent the number of integer
cells in the dmas property of client device.
- dma-channels: Physical channels supported.
- dma-requests: Number of DMA request signals supported by the controller.
Refer to Documentation/devicetree/bindings/dma/dma.txt
- clocks: Phandle and Specifier of the clock feeding the DMA controller.
Example:
Controller:
dma: dma-controller@e0260000 {
compatible = "actions,s900-dma";
reg = <0x0 0xe0260000 0x0 0x1000>;
interrupts = <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 59 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 60 IRQ_TYPE_LEVEL_HIGH>;
#dma-cells = <1>;
dma-channels = <12>;
dma-requests = <46>;
clocks = <&clock CLK_DMAC>;
};
Client:
DMA clients connected to the Actions Semi Owl SoCs DMA controller must
use the format described in the dma.txt file, using a two-cell specifier
for each channel.
The two cells in order are:
1. A phandle pointing to the DMA controller.
2. The channel id.
