[PATCH net v6 0/5] net: macb: various fixes

["Théo Lebrun" <theo.lebrun@bootlin.com>]

This would have been a RESEND if it wasn't for that oneline RCT fix.
Rebased and tested on the latest net/main as well, still working fine
on EyeQ5 hardware.

Fix a few disparate topics in MACB:

[PATCH net v6 1/5] dt-bindings: net: cdns,macb: allow tsu_clk without tx_clk
[PATCH net v6 2/5] net: macb: remove illusion about TBQPH/RBQPH being per-queue
[PATCH net v6 3/5] net: macb: move ring size computation to functions
[PATCH net v6 4/5] net: macb: single dma_alloc_coherent() for DMA descriptors
[PATCH net v6 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, (2) patches for
EyeQ5 support and (3) XDP work. Those will be sent targeting
net-next/main once this series lands there, aiming to minimise merge
conflicts. Old version of(1) and (2) are visible in the V2 revision [0].

Thanks,
Have a nice day,
Théo

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
