[PATCH v2 1/1] phy: rockchip: naneng-combphy: compatible reset with old DT

[Chukun Pan]

The device tree of RK3568 did not specify reset-names before.
So add fallback to old behaviour to be compatible with old DT.

The commit fbcbffbac994 ("phy: rockchip: naneng-combphy: fix phy reset")
broke backwards compatibly with old DTs and has already been backported
breaking i.e. PCIe and USB on Rockchip RK356x boards on stable and
longterm kernels.

E.g with v6.12.9 on a Radxa ROCK 3A (RK3568) board:

  rockchip-naneng-combphy fe830000.phy: error -ENOENT: failed to get phy reset
  rockchip-naneng-combphy fe830000.phy: probe with driver rockchip-naneng-combphy failed with error -2

  rockchip-naneng-combphy fe840000.phy: probe with driver rockchip-naneng-combphy failed with error -2
  rockchip-naneng-combphy fe820000.phy: error -ENOENT: failed to get phy reset
  rockchip-naneng-combphy fe820000.phy: probe with driver rockchip-naneng-combphy failed with error -2

Please revert the commit fbcbffbac994 ("phy: rockchip: naneng-combphy:

The original commit broke ABI and does not allow upgrading Linux using
an existing device tree, even if the DT patch adding reset-names props
also is backported you still have uses in the wild e.g. U-Boot v2024.10
and newer that comes bundled with an unpatched DT.

Trying to boot into Linux v6.1.123+, v6.6.69+ and v6.12.8+ using the 
U-Boot bundled DT for RK356x boards now result in broken PCIe, SATA and
USB thanks to the offending commit fbcbffbac994 ("phy: rockchip:
naneng-combphy: fix phy reset").

That is not *same* behaviour on fallback, why _exclusive() for the
fallback?

That is not *same* behaviour on fallback, why _exclusive() for the
fallback?

Prior to the commit fd3ac6e80497 ("dt-bindings: phy: rockchip: rk3588
has two reset lines") the dt-binding did not require reset-names and it
still does not for the rockchip,rk3568-naneng-combphy compatible. The
binding documentation also mentioned "exclusive PHY reset line" for the
resets prop.

The commit fbcbffbac994 ("phy: rockchip: naneng-combphy: fix phy reset")
broke backward compatibility with the rockchip,rk3568-naneng-combphy
compatible by requiring existence of a "phy" in reset-names.

This patch restores the old behavior prior to fbcbffbac994 ("phy:
rockchip: naneng-combphy: fix phy reset") when
devm_reset_control_array_get_exclusive() was used to restore
compatibility with the rockchip,rk3568-naneng-combphy dt-binding.

Jonas

Thanks for your work!
We found your patch after NVMes stopped working on a rock 3A with newer 
kernels and successfully applied it to kernel 6.1.128 (currently in debian).

As the commit breaking NVMe functionality on rk3568 platforms 
(fd3ac6e80497 "phy: rockchip: naneng-combphy: fix phy reset") was 
already backported to 6.1.y, 6.6.y, 6.12.y it would be great to have 
this fix in these releases as well.

Best regards,
Valentin

FTR: I've reported it in Debian here: https://bugs.debian.org/1098250

I confirmed it (also) broke on kernel 6.12.8-1.

FWIW, we have several users in Debian reporting the problem, so if it
can be applied to mainline and then flow down to one of the next round
of stable series down to 6.1.y that would be highly appreicated.

Diederik, if you were able to test the fix, you might contribute a
Tested-by (although as I undestsand its not strictly needed at this
point as commit should be on way to mainline and stable series)?

Salvatore

FWIW, we have several users in Debian reporting the problem, so if it
can be applied to mainline and then flow down to one of the next round
of stable series down to 6.1.y that would be highly appreicated.

Diederik, if you were able to test the fix, you might contribute a
Tested-by (although as I undestsand its not strictly needed at this
point as commit should be on way to mainline and stable series)?

Salvatore

AFAIK a Tested-by could increase the chances of the maintainer accepting
the patch, but that has already happened (commit date: 2025-02-04).
The patch was already verified to fix the problem before submission:
https://lore.kernel.org/all/20250103171109.2726312-1-liujianfeng1994@gmail.com/

So AFAICT another Tested-by would either have no effect or a delaying
effect (adding it would change a bunch of commit IDs probably triggering
various CIs to run again).
I'm not aware of anything (else) I could do wrt this patch.

Cheers,
  Diederik

the patch already is in the fixes-branch of the phy-tree [0], sho should
make its way into 6.14-rc shortly.
