This driver supports the Common Platform Time Sync unit of
the CPSW Ethernet Switch and Keystone 2 1g/10g Switch Subsystem.
The unit can time stamp PTP UDP/IPv4 and Layer 2 packets, and the
driver offers a PTP Hardware Clock.

My recent commit b6d49cab44b5 ("net: Make PTP-specific drivers depend on PTP_1588_CLOCK") exposes a missing dependency in defconfigs that select TI_CPTS without selecting PTP_1588_CLOCK, leading to linker errors of the form: drivers/net/ethernet/ti/cpsw.o: in function `cpsw_ndo_stop': cpsw.c:(.text+0x680): undefined reference to `cpts_unregister' drivers/net/ethernet/ti/cpsw.o: in function `cpsw_remove': cpsw.c:(.text+0x81c): undefined reference to `cpts_release' drivers/net/ethernet/ti/cpsw.o: in function `cpsw_rx_handler': cpsw.c:(.text+0x1324): undefined reference to `cpts_rx_timestamp' drivers/net/ethernet/ti/cpsw.o: in function `cpsw_ndo_open': cpsw.c:(.text+0x15ec): undefined reference to `cpts_register' drivers/net/ethernet/ti/cpsw.o: in function `cpsw_probe': cpsw.c:(.text+0x2468): undefined reference to `cpts_release' That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ of cpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in these configurations, but TI_CPTS (which is the symbol gating _calls_ to the cpts functions) _is_ enabled. So we end up compiling calls to functions that don't exist, resulting in the linker errors. The reason we have two symbols (TI_CPTS and TI_CPTS_MOD) for the same driver is due to commit be9ca0d33c85 ("cpsw/netcp: work around reverse cpts dependency"), which introduced TI_CPTS_MOD because (quoting the commit message): > The dependency is reversed: cpsw and netcp call into cpts, > but cpts depends on the other two in Kconfig. This can lead > to cpts being a loadable module and its callers built-in: > > drivers/net/ethernet/ti/cpsw.o: In function `cpsw_remove': > cpsw.c:(.text.cpsw_remove+0xd0): undefined reference to `cpts_release' > drivers/net/ethernet/ti/cpsw.o: In function `cpsw_rx_handler': > cpsw.c:(.text.cpsw_rx_handler+0x2dc): undefined reference to `cpts_rx_timestamp' > drivers/net/ethernet/ti/cpsw.o: In function `cpsw_tx_handler': > cpsw.c:(.text.cpsw_tx_handler+0x7c): undefined reference to `cpts_tx_timestamp' > drivers/net/ethernet/ti/cpsw.o: In function `cpsw_ndo_stop': Both forms of linker error -- those caused by defconfigs that select TI_CPTS without PTP_1588_CLOCK and those caused by configuring TI_CPSW as a built-in and TI_CPTS as a module -- can be avoided by using the IS_REACHABLE() macro to gate calls to cpts functions, and using the TI_CPTS symbol to gate compilation of cpts.c. cpts.h already provides the no-op stub implementations of the cpts functions required to make this work, we just need to change the existing IS_ENABLED(TI_CPTS) guards to IS_REACHABLE(TI_CPTS). With this change there is no longer any need for the TI_CPTS_MOD symbol, so we can remove it. To preserve the existing behavior of defconfigs that select TI_CPTS, we must also select PTP_1588_CLOCK so that the dependency is satisfied. omap2plus_defconfig and keystone_defconfig have not been updated in a while, so some unrelated no-op changes appear in the diff.
