ptp: add kernel API ptp_convert_timestamp()

2021-07-01T20:08:18Z

Add kernel API ptp_convert_timestamp() to convert raw hardware timestamp to a specified ptp vclock time. Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

ptp: add kernel API ptp_get_vclocks_index()

2021-07-01T20:08:18Z

Add kernel API ptp_get_vclocks_index() to get all ptp vclocks index on pclock. This is preparation for supporting ptp vclocks info query through ethtool. Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

ptp: add ptp virtual clock driver framework

2021-07-01T20:08:18Z

This patch is to add ptp virtual clock driver framework utilizing timecounter/cyclecounter. The patch just exports two essential APIs for PTP driver. - ptp_vclock_register() - ptp_vclock_unregister() Signed-off-by: Yangbo Lu Signed-off-by: David S. Miller

Trivial conflicts in net/can/isotp.c and tools/testing/selftests/net/mptcp/mptcp_connect.sh scaled_ppm_to_ppb() was moved from drivers/ptp/ptp_clock.c to include/linux/ptp_clock_kernel.h in -next so re-apply the fix there. Signed-off-by: Jakub Kicinski

ptp: improve max_adj check against unreasonable values

2021-06-15T17:59:46Z

Scaled PPM conversion to PPB may (on 64bit systems) result in a value larger than s32 can hold (freq/scaled_ppm is a long). This means the kernel will not correctly reject unreasonably high ->freq values (e.g. > 4294967295ppb, 281474976645 scaled PPM). The conversion is equivalent to a division by ~66 (65.536), so the value of ppb is always smaller than ppm, but not small enough to assume narrowing the type from long -> s32 is okay. Note that reasonable user space (e.g. ptp4l) will not use such high values, anyway, 4289046510ppb ~= 4.3x, so the fix is somewhat pedantic. Fixes: d39a743511cd ("ptp: validate the requested frequency adjustment.") Fixes: d94ba80ebbea ("ptp: Added a brand new class driver for ptp clocks.")

ptp: ptp_clock: make scaled_ppm_to_ppb static inline

2021-05-10T21:54:23Z

Make scaled_ppm_to_ppb static inline to be able to build drivers that use this function even with PTP_1588_CLOCK disabled. Signed-off-by: Radu Pirea (NXP OSS) Signed-off-by: David S. Miller

ptp: document struct ptp_clock_request members

2020-11-18T18:51:17Z

It's arguable most people interested in configuring a PPS signal want it as external output, not as kernel input. PTP_CLK_REQ_PPS is for input though. Add documentation to nudge readers into the correct direction.

ptp: Add adjphase function to support phase offset control.

2020-05-02T23:31:44Z

Adds adjust phase function to take advantage of a PHC clock's hardware filtering capability that uses phase offset control word instead of frequency offset control word. Signed-off-by: Vincent Cheng Reviewed-by: Richard Cochran Signed-off-by: David S. Miller
