[PATCH v2 00/12] Enable networking support for StarFive JH7100 SoC

[Cristian Ciocaltea <cristian.ciocaltea@collabora.com>]

This patch series adds ethernet support for the StarFive JH7100 SoC and 
makes it available for the StarFive VisionFive V1 and BeagleV Starlight 
boards, although I could only validate on the former SBC.

The work is heavily based on the reference implementation [1] and depends 
the non-coherent DMA support provided by Emil via the SiFive Composable 
Cache controller [2].

Changes in v2:
 - Dropped ccache PATCH 01-05 reworked by Emil via [2]
 - Dropped already applied PATCH 06/12
 - Added PATCH v2 01 to prepare snps-dwmac binding for JH7100 support
 - Added PATCH v2 02-03 to provide some jh7110-dwmac binding optimizations
 - Handled JH7110 conflicting work in PATCH 07 via PATCH v2 04
 - Reworked PATCH 8 via PATCH v2 05, adding JH7100 quirk and dropped
 - starfive,gtxclk-dlychain DT property, also fixed register naming
 - Added PATCH v2 08 providing DMA coherency related DT changes
 - Updated PATCH 9 commit msg:
   s/OF_DMA_DEFAULT_COHERENT/ARCH_DMA_DEFAULT_COHERENT/
 - Replaced 'uncached-offset' property with 'sifive,cache-ops' 
   in PATCH 10/12 and dropped 'sideband' reg
 - Add new patch providing coherent DMA memory pool (PATCH v2 10)
 - Updated PATCH 11/12 according to the stmmac glue layer changes in
   upstream
 - Split PATCH 12/12 into PATCH v2 10-12 to handle individual gmac setup of
   VisionFive v1 and BeagleV boards as they use different PHYs; also
   switched phy-mode from "rgmii-tx" to "rgmii-id" (requires a reduction of
   rx-internal-delay-ps by ~50%)
 - Rebased series onto next-20231024
 - v1: https://lore.kernel.org/lkml/20230211031821.976408-1-cristian.ciocaltea@collabora.com/
