Qcom Slimbus controller driver is totally unused and dead code, there is no point in keeping this driver in the kernel without users. This patch removes the driver along with device tree bindings.

SLIMbus is a 2-wire bus, and is used to communicate with peripheral
|
|
components like audio-codec.

pattern: "^slim(@.*|-([0-9]|[1-9][0-9]+))?$"

Every SLIMbus controller node can contain zero or more child nodes
|
|
representing slave devices on the bus. Every SLIMbus slave device is
|
|
uniquely determined by the enumeration address containing 4 fields::
|
|
Manufacturer ID, Product code, Device index, and Instance value for the
|
|
device.
|
|
|
|
If child node is not present and it is instantiated after device
|
|
discovery (slave device reporting itself present).
|
|
|
|
In some cases it may be necessary to describe non-probeable device
|
|
details such as non-standard ways of powering up a device. In such cases,
|
|
child nodes for those devices will be present as slaves of the SLIMbus
|
|
controller.

Pair of (device index, instande ID), where::
|
|
- Device index, which uniquely identifies multiple devices within a
|
|
single component.
|
|
- Instance ID, can be used for the cases where multiple devices of
|
|
the same type or class are attached to the bus.
