When PTP packets are received on ICSS ports, dual_emac firmware record the
timestamps and appends the timestamp at the next 32 byte block after the end
of packet. Add support for reading this timestamp from packet and pass
it to userspace layer.

When PTP support is enabled in hsr firmware, the firmware timestamps
the ptp packets that are going out via prueth ports. The timestamp value
is copied to a shared memory location. After timestamping, a host irq is
raised by the firmware as a notification to read the timestamp.

Add support for handling this ptp tx irq, read the tx timestamp and pass
it to userspace layer.

The MCU CPSW expected to populate only MDIO device, but follow up patches
will add "compatible" property to the MCU CPSW CPTS node which will cause

Add new API k3_ringacc_request_rings_pair() to request pair of rings at

one to receive completions (RX/TX CQ). This will allow to simplify Ringacc

The CAP3 register contains information about the number of
HCHAN (High Capacity) and UCHAN (Ultra High Capacity) channels in UDMAP.

Based on this information the start indexes of the levels can be calculated
without a need of a table in the match data.

On am654 the CAP3 does not contain information about the number different
channels. Set up the tpl information beased on the available documentation.

This change will allow to use the same compatible for different SoCs where
the only difference is the number of channel types.
