PLATFORM_DEVICE_REGI(9) Device drivers infrastructure PLATFORM_DEVICE_REGI(9)NAMEplatform_device_register_simple - add a platform-level device and its
resources
SYNOPSIS
struct platform_device *
platform_device_register_simple(const char * name,
int id,
const struct resource * res,
unsigned int num);
ARGUMENTS
name
base name of the device we're adding
id
instance id
res
set of resources that needs to be allocated for the device
num
number of resources
DESCRIPTION
This function creates a simple platform device that requires minimal
resource and memory management. Canned release function freeing memory
allocated for the device allows drivers using such devices to be
unloaded without waiting for the last reference to the device to be
dropped.
This interface is primarily intended for use with legacy drivers which
probe hardware directly. Because such drivers create sysfs device nodes
themselves, rather than letting system infrastructure handle such
device enumeration tasks, they don't fully conform to the Linux driver
model. In particular, when such drivers are built as modules, they
can't be “hotplugged”.
Returns struct platform_device pointer on success, or ERR_PTR on error.
