[PATCH net-next v2 00/11] net: ethernet: qualcomm: ppe: Add support for IPQ5424 SoC

[Luo Jie]

This series adds support in the PPE driver for the IPQ5424 SoC.

IPQ5424 integrates the same PPE switch core as IPQ9574, but with a few
differences:

1.) It has 3 Ethernet ports plus 1 EDMA FIFO, instead of IPQ9574's 6 ports,
    1 EDMA FIFO and 1 EIP FIFO.
2.) The PPE clock runs at 375 MHz instead of IPQ9574's 353 MHz.
3.) It requires a different, smaller set of interconnect paths.
4.) It uses different BM (buffer management), QM (queue management) and
    scheduler configurations.

The first two patches are independent of the IPQ5424 support and correct
issues in the existing IPQ9574 support:
 - Split the EDMA reset in the devicetree binding into the separate system
   and APB resets.
 - Fix the multicast queue configuration table access, which uses an
   out-of-range index for every multicast queue on both IPQ9574 and
   IPQ5424, and accesses 5 words per entry instead of 3.

The remaining patches add the IPQ5424 support:
 - Add IPQ5424 to the devicetree binding.
 - Document IPQ5424 as a supported SoC.
 - Add the IPQ5424 platform data for the clock rate, port count, register
   space and interconnect paths.
 - Add the IPQ5424 BM buffer configuration.
 - Add the IPQ5424 QM configuration.
 - Add the IPQ5424 scheduler resource configuration.
 - Add the IPQ5424 scheduler configuration.
 - Add the IPQ5424 service code configuration.
 - Add the IPQ5424 counters for debugfs.

Changes in v2:
- Drop the Fixes: tags from the first two patches, as they target
  net-next and have no known user impact.
- Fix the multicast queue configuration entry size (5 words -> 3) in
  the multicast queue fix patch, and update its subject.
- Match all Ethernet port nodes in the binding, so that out-of-range
  ports are rejected by the reg limits.
- Collect the Reviewed-by tags.
