X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=94798081732abfb5748471d5c3cced6ff187fa36;p=thirdparty%2Fkernel%2Flinux.git

driver core: platform: add kerneldoc to struct platform_device_info

Add kernel documentation for struct platform_device_info and its
individual members. While at it remove an extra indent level from the
structure definition.

+/**
+ * struct platform_device_info - set of parameters for creating a platform device
+ * @parent: parent device for the new platform device.
+ * @fwnode: firmware node associated with the device.
+ * @of_node_reused: indicates that device tree node associated with the device
+ *	is shared with another device, typically its ancestor. Setting this to
+ *	%true prevents the device from being matched via the OF match table,
+ *	and stops the device core from automatically binding pinctrl
+ *	configuration to avoid disrupting the other device.
+ * @name: name of the device.
+ * @id: instance ID of the device. Use %PLATFORM_DEVID_NONE if there is only
+ *	one instance of the device, or %PLATFORM_DEVID_AUTO to let the
+ *	kernel automatically assign a unique instance ID.
+ * @res: set of resources to attach to the device.
+ * @num_res: number of entries in @res.
+ * @data: device-specific data for this platform device.
+ * @size_data: size of device-specific data.
+ * @dma_mask: DMA mask for the device.
+ * @properties: a set of software properties for the device. If provided,
+ *	a managed software node will be automatically created and
+ *	assigned to the device. The properties array must be terminated
+ *	with a sentinel entry.
+ *
+ * This structure is used to hold information needed to create and register
+ * a platform device using platform_device_register_full().
+ *
+ * platform_device_register_full() makes deep copies of @name, @res, @data and
+ * @properties, so the caller does not need to keep them after registration.
+ * If the registration is performed during initialization, these can be marked
+ * as __initconst.
