[PATCH v7 0/3] Add MACB/GEM instances on EyeQ5, and their PHYs
From: Théo Lebrun
Date: Wed Feb 25 2026 - 12:01:07 EST
EyeQ5 SoCs integrate two GEM instances. A system-controller register
region named "OLB" has some control over the Ethernet PHY integration.
Extend the current OLB ecosystem with a new generic PHY driver.
- OLB is carried by one main platform driver: clk-eyeq.
- It instantiates auxiliary devices: reset-eyeq & pinctrl-eyeq5.
- We add a new one: phy-eyeq5-eth.
Here we update dt-bindings to indicate OLB is a PHY provider. Then we
add MACB/GEM instances in the devicetree, and the PHYs on the eval
board.
About related patches:
- PHY patches are incoming to add the driver. Patches used to be [2] in
the same series.
- clk patches are incoming to make clk-eyeq instantiate this new
auxiliary device. They also ensure we get a dev->of_node assigned.
Patches used to be [2] in the same series.
Have a nice day,
Thanks!
Théo

Changes in v7:
- Separate PHY / clk / MIPS patches into three series.
- Rebase onto v7.0-rc1 and test on EyeQ5. Nothing to report.
- Link to v6: https://lore.kernel.org/r/20260127-macb-phy-v6-0-cdd840588188@xxxxxxxxxxx
Changes in v6:
- Rebase upon v6.19-rc7; nothing to report.
- Add new patch "phy: sort Kconfig and Makefile".
- phy-eyeq5-eth: drop useless explicit __iomem cast to
dev_get_platdata() return value.
- I did *not* drop the Kconfig `default MACH_EYEQ5` nor driver
`dev_dbg()`. I think both are useful and should be kept. See
last revision discussion here:
https://lore.kernel.org/lkml/DFGSMN8268O0.33TYCQDBVHUHZ@xxxxxxxxxxx/
- Link to v5: https://lore.kernel.org/r/20251215-macb-phy-v5-0-a9dfea39da34@xxxxxxxxxxx
Changes in v5:
- phy-eyeq5-eth:
- fix #includes: add delay, gfp_types, module and drop array_size,
bug, cleanup, container_of, lockdep, mutex.
- eq5_phy_xlate(): avoid magic value, use EQ5_PHY_COUNT.
- use dev_err_probe() in error cases of devm_phy_create() and
devm_of_phy_provider_register().
- 3x Reviewed-by: Luca Ceresoli.
- Add Neil Armstrong to Cc as new PHY subsystem reviewer.
- Rebase on v6.19-rc1, tested on hardware, no changes.
- Link to v4: https://lore.kernel.org/r/20251124-macb-phy-v4-0-955c625a81a7@xxxxxxxxxxx
Changes in v4:
- Append my SoB to Jerome's patch:
[PATCH v4 3/7] clk: eyeq: use the auxiliary device creation helper
- Rebase on net-next & linux-{clk,mips,phy}. Nothing to report.
- Link to v3: https://lore.kernel.org/r/20251119-macb-phy-v3-0-e9a7be186a33@xxxxxxxxxxx
Changes in v3:
- Take Philipp Zabel's Reviewed-by & Acked-by trailers on reset patch.
- Take Thomas Bogendoerfer's two Acked-by trailers on DT patches.
- Rebase on net-next & test on target. Nothing to report.
- Link to v2: https://lore.kernel.org/r/20251101-macb-phy-v2-0-c1519eef16d3@xxxxxxxxxxx
Changes in v2:
- Take Acked-by: Conor Dooley on dt-bindings-patch.
- s/%ld/%tu/ for printing ptrdiff_t; warnings on 32-bit archs.
Reported by NIPA's netdev/build_32bit test.

Changes since MACB V1:
- Drop the old "mobileye,olb" properties from DT patches; found while
running dtbs_check and dt_binding_check.
- Drop all patches targeting net-next. That is MACB dt-bindings patch
and MACB driver code. See there here [1].
