Merge branch 'dpll-support-mode-switching'
Ivan Vecera says:
====================
dpll: support mode switching
This series adds support for switching the working mode (automatic vs
manual) of a DPLL device via netlink.
Currently, the DPLL subsystem allows userspace to retrieve the current
working mode but lacks the mechanism to configure it. Userspace is also
unaware of which modes a specific device actually supports, as it
currently assumes only the active mode is supported.
The series addresses these limitations by:
1. Introducing .supported_modes_get() callback to allow drivers to report
all modes capable of running on the device.
2. Introducing .mode_set() callback and updating the netlink policy
to allow userspace to request a mode change.
3. Implementing these callbacks in the zl3073x driver, enabling dynamic
switching between automatic and manual modes.
