*	netdev: expose DPLL pin handle for netdevice	Jiri Pirko	2023-09-17	1	-2/+14
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	In case netdevice represents a SyncE port, the user needs to understand the connection between netdevice and associated DPLL pin. There might me multiple netdevices pointing to the same pin, in case of VF/SF implementation. Add a IFLA Netlink attribute to nest the DPLL pin handle, similar to how it is implemented for devlink port. Add a struct dpll_pin pointer to netdev and protect access to it by RTNL. Expose netdev_dpll_pin_set() and netdev_dpll_pin_clear() helpers to the drivers so they can set/clear the DPLL pin relationship to netdev. Note that during the lifetime of struct dpll_pin the pin handle does not change. Therefore it is save to access it lockless. It is drivers responsibility to call netdev_dpll_pin_clear() before dpll_pin_put().

*	dpll: netlink: Add DPLL framework base functions	Vadim Fedorenko	2023-09-17	1	-0/+1241
	DPLL framework is used to represent and configure DPLL devices in systems. Each device that has DPLL and can configure inputs and outputs can use this framework. Implement dpll netlink framework functions for enablement of dpll subsystem netlink family.
