Subject: [PATCH net-next 00/15] net: macb: various cleanups

Fix many oddities inside the MACB driver. They accumulated in my
work-in-progress branch while working on MACB/GEM EyeQ5 support.

Part of this series has been seen on the lkml in March then June.
See below for a semblance of a changelog.

The initial goal was to post them alongside EyeQ5 support, but that
makes for too big of a series. It'll come afterwards, with new
features (interrupt coalescing, ethtool .set_channels() and XDP mostly).

Thanks,
Have a nice day,
Théo

Changes since June V2:
 - Six patches are straight copies:
   dt-bindings: net: cdns,macb: sort compatibles
   net: macb: use BIT() macro for capability definitions
   net: macb: Remove local variables clk_init and init in macb_probe()
   net: macb: drop macb_config NULL checking
   net: macb: introduce DMA descriptor helpers (is 64bit? is PTP?)
   net: macb: sort #includes
 - The "introduce DMA descriptor helpers" patch was split in two:
   net: macb: simplify macb_dma_desc_get_size()
   net: macb: introduce DMA descriptor helpers (is 64bit? is PTP?)
 - Three patches come from Sean's feedback:
   net: macb: remove gap in MACB_CAPS_* flags
   net: macb: simplify macb_adj_dma_desc_idx()
   net: macb: move bp->hw_dma_cap flags to bp->caps
 - Take 1x Reviewed-by: Krzysztof Kozlowski
