Because the ice_dpll.c file is compiled unconditionally, it will not link when CONFIG_PTP_1588_CLOCK=n. It might be possible to break this dependency and expose those functions without CONFIG_PTP_1588_CLOCK, but that is not clear to me. For the DPLL case, simply compile ice_dpll.o only when we have CONFIG_PTP_1588_CLOCK. Add stub no-op implementation of ice_dpll_init() and ice_dpll_uninit() when CONFIG_PTP_1588_CLOCK=n into ice_dpll.h The other functions are part of checking the netlist to see if hardware features are enabled. These checks don't really belong in ice_ptp_hw.c, and make more sense as part of the ice_common.c file. We already have ice_is_gps_in_netlist() in ice_common.c which is doing a similar check. Move the functions into ice_common.c and rename them to have the similar postfix of "in_netlist()" to be more expressive of what they are actually checking. This also makes the ice_find_netlist_node only called from within ice_common.c, so its safe to mark it static and stop declaring it in the ice_common.h header as well.
