Slower half cycle time than 70msec can be\nprogrammed also as long as the output clock is synchronized to whole\nseconds, useful specifically for generating a 1Hz clock.\n\nPermitted values for the clock half cycle time are: 125,000,000 decimal,\n250,000,000 decimal and 500,000,000 decimal (equals to 125msec, 250msec\nand 500msec respectively).\n\nBefore this patch, only the half cycle time of less than or equal to 70msec\nuses the I210 clock output function. This patch adds additional conditions\nwhen half cycle time is equal to 125msec or 250msec or 500msec to use\nclock output function.\n\nUnder other conditions, interrupt driven target time output events method\nis still used to generate the desired clock output.\n\nSigned-off-by: Roland Hii <roland.king.guan.hii@intel.com>\n---\n drivers/net/ethernet/intel/igb/igb_ptp.c | 3 ++-\n 1 file changed, 2 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/igb/igb_ptp.c b/drivers/net/ethernet/intel/igb/igb_ptp.c\nindex c44df87..22a8a29 100644\n--- a/drivers/net/ethernet/intel/igb/igb_ptp.c\n+++ b/drivers/net/ethernet/intel/igb/igb_ptp.c\n@@ -525,7 +525,8 @@ static int igb_ptp_feature_enable_i210(struct ptp_clock_info *ptp,\n \t\tts.tv_nsec = rq->perout.period.nsec;\n \t\tns = timespec64_to_ns(&ts);\n \t\tns = ns >> 1;\n-\t\tif (on && ns <= 70000000LL) {\n+\t\tif (on && ((ns <= 70000000LL) || (ns == 125000000LL) ||\n+\t\t\t (ns == 250000000LL) || (ns == 500000000LL))) {\n \t\t\tif (ns < 8LL)\n \t\t\t\treturn -EINVAL;\n \t\t\tuse_freq = 1;\n", "prefixes": [] }
