Stewart Smith c48557366d hvc_opal: don't set tb_ticks_per_usec in udbg_init_opal_common() ... [ Upstream commit 447808bf50 ] time_init() will set up tb_ticks_per_usec based on reality. time_init() is called *after* udbg_init_opal_common() during boot. from arch/powerpc/kernel/time.c: unsigned long tb_ticks_per_usec = 100; /* sane default */ Currently, all powernv systems have a timebase frequency of 512mhz (512000000/1000000 == 0x200) - although there's nothing written down anywhere that I can find saying that we couldn't make that different based on the requirements in the ISA. So, we've been (accidentally) thwacking the (currently) correct (for powernv at least) value for tb_ticks_per_usec earlier than we otherwise would have. The "sane default" seems to be adequate for our purposes between udbg_init_opal_common() and time_init() being called, and if it isn't, then we should probably be setting it somewhere that isn't hvc_opal.c!
