I want to compare v4l2_buf timestamp with system time got with clock_gettime().
But time got with clock_gettime() is starting from tx2 kernel starting.
Time got with v4l2_buf timesstamp is starting from tx2 u-boot starting.
I think there is a u-boot(before kernel starting) time between them.
I also have tried setting cbootargs tegra_keep_boot_clocks=0 or =1 , but can not make it.
I try it on R28.2.1 and R28.3.
But on tx1 R28.2 the time is ｕｎｉform.
Can I make them count base on the same start point.
