This adds an init-time configuration framework that parses configuration
data from an ACPI property table. The table is assumed to have well
defined sub-device property tables that correspond to the various
driver components. Initially the following sub-device tables are
defined:
CRTC (CRTC)
The CRTC sub-device table contains additional sub-device tables
where each one corresponds to a CRTC. Each CRTC sub-device must
include a property called "id" whose value matches the driver's
crtc id. Additional properties for the CRTC are used to configure
the crtc.
Connector (CNCT)
The CNCT sub-device table contains additional sub-device tables
where each one corresponds to a connector. Each of the connector
sub-device tables must include a property called "name" whose value
matches a connector name assigned by the driver (see later patch
for output name function). Additional connector properties can
be set through these tables.
Plane (PLNS)
The PLNS sub-device table contains additional sub-device tables
where each one corresponds to a plane. [this needs additional work]
In addition, the main device property table for the device may
contain configuration information that applies to general driver
configuration.
The framework includes a couple of helper functions to access the
configuration data.
intel_config_get_integer() will look up a configuration property
and return the integer value associated with it.
intel_config_init_<component>_property() will look up a
configuration property and assign the value to a drm
property of the same name. These functions are used to
initialize drm property instances to specific values.
