[PATCH net-next 08/11] ice: add admin commands to access cgu configuration

Vadim Fedorenko
2023-07-20T09:31:05Z

From: Arkadiusz Kubalewski <arkadiusz.kubalewski@intel.com>

Add firmware admin command to access clock generation unit
configuration, it is required to enable Extended PTP and SyncE features
in the driver.
Add definitions of possible hardware variations of input and output pins
related to clock generation unit and functions to access the data.

RFC v9->v0:
- add support for DPLL_MODE_FREERUN mode
- remove freq from ice_aq_get_phy_rec_clk_out() as no longer supported
- add node_handle out argument to ice_aq_get_phy_rec_clk_out()

v8->v9:
- rename MAX_NETLIST_SIZE -> ICE_MAX_NETLIST_SIZE
- simplify function: s64 convert_s48_to_s64(s64 signed_48)
- do not assign 0 to field that is already 0
