Subject: [v3, 00/10] Support DPAA PTP clock and timestamping

This patchset is to support DPAA FMAN PTP clock and HW timestamping.
It had been verified on both ARM platform and PPC platform.
- The patch #1 to patch #5 are to support DPAA FMAN 1588 timer in
ptp_qoriq driver.
- The patch #6 to patch #10 are to add HW timestamping support in
DPAA ethernet driver.

Yangbo Lu (10):
fsl/fman: share the event interrupt
ptp: support DPAA FMan 1588 timer in ptp_qoriq
dt-binding: ptp_qoriq: add DPAA FMan support
powerpc/mpc85xx: move ptp timer out of fman in dts
arm64: dts: fsl: move ptp timer out of fman
fsl/fman: add set_tstamp interface
fsl/fman_port: support getting timestamp
fsl/fman: define frame description command UPD
dpaa_eth: add support for hardware timestamping
dpaa_eth: add the get_ts_info interface for ethtool

Subject: [v3, 09/10] dpaa_eth: add support for hardware timestamping

This patch is to add hardware timestamping support
for dpaa_eth. On Rx, timestamping is enabled for
all frames. On Tx, we only instruct the hardware
to timestamp the frames marked accordingly by the
stack.

Signed-off-by: Yangbo Lu <[email protected]>
---
Changes for v2:
- Removed ifdef for timestamp code.
- Minor fixes for code style.
Changes for v3:
- Moved tstamp endianness conversion to fman API.
- Fixed fm.cmd endianness.

Subject: [v3, 02/10] ptp: support DPAA FMan 1588 timer in ptp_qoriq

This patch is to support DPAA (Data Path Acceleration Architecture)
1588 timer by adding "fsl,fman-ptp-timer" compatible, sharing
interrupt with FMan, adding FSL_DPAA_ETH dependency, and fixing
up register offset.

Subject: [v3, 04/10] powerpc/mpc85xx: move ptp timer out of fman in dts

This patch is to move ptp timer node out of fman.
Because ptp timer will be probed by ptp_qoriq driver,
it should be an independent device in case of conflict
memory mapping.
