Hi all, This series adds support for the PTP offloading support in the Mscc Ocelot Ethernet switch driver. Both PTP 1-step and 2-step modes are supported.
In order to make use of the PTP offloading support, two new register banks were described in the Ocelot device tree. The use of those registers by the Mscc Ocelot Ethernet switch driver is made optional for dt compatibility reasons. For the same reason a new interrupt is described, and its use is also made optinal for compatibility reasons. All of this is done ine patches 1-5. The PTP offloading support itself is added in patch 8. While doing this support, a few reworks were done in the Ocelot switch driver, in patches 6-7. Patches 2 and 4 should probably go through the MIPS tree. Thanks!
