    cpsw/netcp: work around reverse cpts dependency · be9ca0d3
    Arnd Bergmann authored
    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':
    
    As a workaround, I'm introducing another Kconfig symbol to
    control the compilation of cpts, while making the actual
    module controlled by a silent symbol that is =y when necessary.
