[PATCH net v5 0/5] net: macb: various fixes

Fix a few disparate topics in MACB:

[PATCH net v5 0/5] net: macb: various fixes
[PATCH net v5 1/5] dt-bindings: net: cdns,macb: allow tsu_clk without tx_clk
[PATCH net v5 2/5] net: macb: remove illusion about TBQPH/RBQPH being per-queue
[PATCH net v5 3/5] net: macb: move ring size computation to functions
[PATCH net v5 4/5] net: macb: single dma_alloc_coherent() for DMA descriptors
[PATCH net v5 5/5] net: macb: avoid dealing with endianness in macb_set_hwaddr()

Patch 3/5 is a rework that simplifies patch 4/5. It is the only non-fix.

Pending series on MACB are: (1) many cleanup patches and (2) patches for
EyeQ5 support. Those will be sent targeting net-next/main once this
series lands there, aiming to minimise merge conflicts. Old version of
those patches are visible in the V2 revision [0].

Thanks,
Have a nice day,
Théo

Changes in v5:
- Fix hwaddr endianness patch following comment by Russell [2].

Changes in v4:
- Drop 11 patches that are only cleanups. That includes the
  RBOF/skb_reserve() patch that, after discussion with Sean [1], has
  had its Fixes trailer dropped. "move ring size computation to
  functions" is the only non-fix patch that is kept, as it is depended
  upon by further patches. Dropped patches:
    dt-bindings: net: cdns,macb: sort compatibles
    net: macb: match skb_reserve(skb, NET_IP_ALIGN) with HW alignment
    net: macb: use BIT() macro for capability definitions
    net: macb: remove gap in MACB_CAPS_* flags
    net: macb: Remove local variables clk_init and init in macb_probe()
    net: macb: drop macb_config NULL checking
    net: macb: simplify macb_dma_desc_get_size()
    net: macb: simplify macb_adj_dma_desc_idx()
    net: macb: move bp->hw_dma_cap flags to bp->caps
    net: macb: introduce DMA descriptor helpers (is 64bit? is PTP?)
    net: macb: sort #includes

- dt-bindings: Take 2x Reviewed-by Krzysztof.
- dt-bindings: add Fixes trailer to "allow tsu_clk without tx_clk"
  patch, to highlight we are not introducing new behavior.
- Reorder commits; move fixes first followed by cleanup patches.
- Drop all EyeQ5 related commits.
- New commit: "remove gap in MACB_CAPS_* flags".
- New commit: "move ring size computation to functions".
- New commit: "move bp->hw_dma_cap flags to bp->caps".
- Rename introduced helpers macb_dma_is_64b() to macb_dma64() and,
  macb_dma_is_ptp() to macb_dma_ptp().
- Rename MACB_CAPS_RSC_CAPABLE -> MACB_CAPS_RSC.
- Fix commit message typos: "maxime" -> "maximise", etc.
- Take 7x Reviewed-by: Sean Anderson.
- Add details to some commit messages.
