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

From: Cristian Ciocaltea
Date: Sun Oct 29 2023 - 00:27:53 EST


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@xxxxxxxxxxxxx/
