Subject: [PATCH v4 0/9] Enable networking support for StarFive JH7100 SoC
Date: Mon, 18 Dec 2023 23:44:40 +0200 [thread overview]
Message-ID: <20231218214451.2345691-1-cristian.ciocaltea@collabora.com> (raw)
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. Thank you Emil and Geert for helping
with tests on BeagleV!
The work is heavily based on the reference implementation [1] and depends on the
SiFive Composable Cache controller and non-coherent DMA support provided by Emil
via [2] and [3].
*Update*: as of next-20231214, all dependencies have been merged.

[2] https://lore.kernel.org/all/CAJM55Z_pdoGxRXbmBgJ5GbVWyeM1N6+LHihbNdT26Oo_qA5VYA@mail.gmail.com/
[3] https://lore.kernel.org/all/20231130151932.729708-1-emil.renner.berthing@canonical.com/
Changes in v4:
- Restricted double usage of 'ahb' reset name in PATCH 2 (Jessica, Samuel)
- Moved phy reference from PATCH 5 to both PATCH 6 & 7 where the node is
actually defined (Emil, Conor)
- Drop unnecessary gpio include in PATCH 6; also added a DTS comment describing
the rational behind RX internal delay adjustment (Andrew)
- v3:
https://lore.kernel.org/lkml/20231215204050.2296404-1-cristian.ciocaltea@collabora.com/
Changes in v3:
- Rebased series onto next-20231214 and dropped the ccache & DMA coherency
related patches (v2 06-08/12) handled by Emil via [3]
- Squashed PATCH v2 01/12 into PATCH v3 2/9, per Krzysztof's review
- Dropped incorrect PATCH v2 02/12
- Incorporated Emil's feedback; also added his Co-developed-by on all dts
patches
- Documented the need of adjusting RX internal delay in PATCH v3 8/9, per
Andrew's request
- Added clock fixes from Emil (PATCH v3 8-9/9) required to support 10/100Mb
link speeds
- v2:
https://lore.kernel.org/lkml/20231029042712.520010-1-cristian.ciocaltea@collabora.com/
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/
