ptp: ptp_clockmatrix: Add .getmaxphase ptp_clock_info callback

2023-06-20T08:02:33Z

Advertise the maximum offset the .adjphase callback is capable of supporting in nanoseconds for IDT ClockMatrix devices. Depend on ptp_clock_adjtime for handling out-of-range offsets. ptp_clock_adjtime returns -ERANGE instead of clamping out-of-range offsets.

ptp: ptp_clockmatrix: Add PTP_CLK_REQ_EXTTS support

2022-05-18T00:49:04Z

Use TOD_READ_SECONDARY for extts to keep TOD_READ_PRIMARY for gettime and settime exclusively. Before this change, TOD_READ_PRIMARY was used for both extts and gettime/settime, which would result in changing TOD read/write triggers between operations. Using TOD_READ_SECONDARY would make extts independent of gettime/settime operation Signed-off-by: Min Li Acked-by: Richard Cochran Link: https://lore.kernel.org/r/1652712427-14703-1-git-send-email-min.li.xe@renesas.com Signed-off-by: Jakub Kicinski

ptp: ptp_clockmatrix: repair non-kernel-doc comment

2021-11-13T03:58:10Z

Do not use "/**" to begin a comment that is not in kernel-doc format. Prevents this docs build warning: drivers/ptp/ptp_clockmatrix.c:1679: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst * Maximum absolute value for write phase offset in picoseconds Then remove the kernel-doc-like function parameter descriptions since they don't add any useful info.

ptp: clockmatrix: use rsmu driver to access i2c/spi bus

2021-09-27T11:16:48Z

rsmu (Renesas Synchronization Management Unit ) driver is located in drivers/mfd and responsible for creating multiple devices including clockmatrix phc, which will then use the exposed regmap and mutex handle to access i2c/spi bus. Signed-off-by: Min Li Signed-off-by: David S. Miller
