[PATCH v5 0/5] RK3568 PCIe V3 support

[PATCH v5 0/5] RK3568 PCIe V3 support

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

This series adds Rockchip PCIe V3 support found on rk3568 SOC.

Compared to PCIeV2 which uses the Naneng combphy, PCIe v3 uses a dedicated
PCI-phy.

v4:
- add reviewed-by
- remove minitems for clock-names as i have static list to fix error
- fix reg error by using 32-bit adressing in binding example
- change lane-map to u32 data-lanes
- tried to move data-lanes to phy-provider
  https://github.com/frank-w/dt-schema/blob/main/dtschema/schemas/phy/phy-provider.yaml#L17
  cloned and installed via pip install -e <local path>
  verified with pip show, but phy-privider seems not to be applied

v3:
- drop quotes
- drop rk3588
- make clockcount fixed to 3
- full path for binding header file
- drop phy-mode and its header and add lane-map

v2:

changes in pcie3 phy yaml
- change clock names to ordered const list
- extend pcie30-phymode description
- add phy-cells to required properties
- drop unevaluatedProperties
- example with 1 clock each line
- use default property instead of text describing it
- update license

Hi,

Right,
original driver has rk3588 support,but we can't test it. Initialization and lane-mapping (bifurcation) was bit different. So we wanted to upstream rk3568 first (but have not removed this part from driver).

I see that someone added rk3588 basic support and if he can test rk3588 i can send compatible for it.

Basic rk3588 support is still WIP. At the moment patches for the CRU
are still pending as well as base DT. I hope to land them for v6.2
(so next merge window). At the same time I don't think PCIe support
is realistic before v6.3.

(so next merge window). At the same time I don't think PCIe support
is realistic before v6.3.

Hi all,

I can confirm this patchset successfully brings up the PCIe 3.0
controller/PHY on an RK3588 - I'm using a Pine64 QuartzPro64, which is
very similar to the Rockchip RK3588-EVB1 board. Runs fine at x1, x2, x4
lane widths and full 8GT/s lane throughput.

The PCIe 2.0 lanes (which use the same PCIe controller driver) need some
changes to the rockchip-naneng-combphy driver that I've not quite gotten
to a working state, but that's unrelated to this series.

I have a (very messy) tree based on v6.0 (on GitHub at [0]) with
Sebastian's other RK3588 support patches dropped in, along with this
series and a few other tweaks. Works quite well :)

So insofar as RK3588 support is concerned,

[PATCH v5 3/5] phy: rockchip: Support PCIe v3

[Frank Wunderlich]

From: Shawn Lin <shawn.lin@rock-chips.com>

RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
It use a dedicated PCIe-phy. Add support for this.

Initial support by Shawn Lin, modifications by Peter Geis and Frank
Wunderlich.

Add data-lanes property for splitting pcie-lanes across controllers.

The data-lanes is an array where x=0 means lane is disabled and  x > 0
means controller x is assigned to phy lane.

v5:
- change pr_* to dev_*, update copyright-years
- add naming of magic constants

v4:
- change u8 lane-map to u32 data-lanes

v3:
- change dt-binding include
- change reset to devm_reset_control_get_optional_exclusive
  exit on error and lower severity of message if unset
- fix from peter: disable reg-write for phy-mode in rockchip_p3phy_probe
- move bifurcation/lane-map support from PCIe to phy driver

v2:
- move dt-bindings header into separate patch
- use BIT-macro
- make constants better readable
- use dev_err instead of pr_*
- change dt-binding include due to renaming (phy-snps-pcie3.h => phy-rockchip-pcie3.h)
- use exclusive variant of devm_reset_control_get{,_exclusive}
- fix semicolon.cocci warnings reported by kernel test robot <lkp@intel.com>

[PATCH v5 3/5] phy: rockchip: Support PCIe v3

[Frank Wunderlich]

From: Shawn Lin <shawn.lin@rock-chips.com>

RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
It use a dedicated PCIe-phy. Add support for this.

Initial support by Shawn Lin, modifications by Peter Geis and Frank
Wunderlich.

Add data-lanes property for splitting pcie-lanes across controllers.

The data-lanes is an array where x=0 means lane is disabled and  x > 0
means controller x is assigned to phy lane.

Suggested-by: Peter Geis <pgwipeout@gmail.com>

v5:
- change pr_* to dev_*, update copyright-years
- add naming of magic constants

v4:
- change u8 lane-map to u32 data-lanes

v3:
- change dt-binding include
- change reset to devm_reset_control_get_optional_exclusive
  exit on error and lower severity of message if unset
- fix from peter: disable reg-write for phy-mode in rockchip_p3phy_probe
- move bifurcation/lane-map support from PCIe to phy driver

v2:
- move dt-bindings header into separate patch
- use BIT-macro
- make constants better readable
- use dev_err instead of pr_*
- change dt-binding include due to renaming (phy-snps-pcie3.h => phy-rockchip-pcie3.h)
- use exclusive variant of devm_reset_control_get{,_exclusive}
- fix semicolon.cocci warnings reported by kernel test robot <lkp@intel.com>

[PATCH v5 3/5] phy: rockchip: Support PCIe v3

[Frank Wunderlich]

From: Shawn Lin <shawn.lin@rock-chips.com>

RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
It use a dedicated PCIe-phy. Add support for this.

Initial support by Shawn Lin, modifications by Peter Geis and Frank
Wunderlich.

Add data-lanes property for splitting pcie-lanes across controllers.

The data-lanes is an array where x=0 means lane is disabled and  x > 0
means controller x is assigned to phy lane.

v5:
- change pr_* to dev_*, update copyright-years
- add naming of magic constants

v4:
- change u8 lane-map to u32 data-lanes

v3:
- change dt-binding include
- change reset to devm_reset_control_get_optional_exclusive
  exit on error and lower severity of message if unset
- fix from peter: disable reg-write for phy-mode in rockchip_p3phy_probe
- move bifurcation/lane-map support from PCIe to phy driver

v2:
- move dt-bindings header into separate patch
- use BIT-macro
- make constants better readable
- use dev_err instead of pr_*
- change dt-binding include due to renaming (phy-snps-pcie3.h => phy-rockchip-pcie3.h)
- use exclusive variant of devm_reset_control_get{,_exclusive}
- fix semicolon.cocci warnings reported by kernel test robot <lkp@intel.com>

[PATCH v5 3/5] phy: rockchip: Support PCIe v3

[Frank Wunderlich]

From: Shawn Lin <shawn.lin@rock-chips.com>

RK3568 supports PCIe v3 using not Combphy like PCIe v2 on rk3566.
It use a dedicated PCIe-phy. Add support for this.

Initial support by Shawn Lin, modifications by Peter Geis and Frank
Wunderlich.

Add data-lanes property for splitting pcie-lanes across controllers.

The data-lanes is an array where x=0 means lane is disabled and  x > 0
means controller x is assigned to phy lane.

Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com>
Suggested-by: Peter Geis <pgwipeout@gmail.com>

v5:
- change pr_* to dev_*, update copyright-years
- add naming of magic constants

v4:
- change u8 lane-map to u32 data-lanes

v3:
- change dt-binding include
- change reset to devm_reset_control_get_optional_exclusive
  exit on error and lower severity of message if unset
- fix from peter: disable reg-write for phy-mode in rockchip_p3phy_probe
- move bifurcation/lane-map support from PCIe to phy driver

v2:
- move dt-bindings header into separate patch
- use BIT-macro
- make constants better readable
- use dev_err instead of pr_*
- change dt-binding include due to renaming (phy-snps-pcie3.h => phy-rockchip-pcie3.h)
- use exclusive variant of devm_reset_control_get{,_exclusive}
- fix semicolon.cocci warnings reported by kernel test robot <lkp@intel.com>

Use consistent naming, so if other nodes have "regulator" suffix, use it
here as well.

only these 3 new have the suffix:

vcc3v3_pi6c_05: vcc3v3-pi6c-05-regulator
vcc3v3_minipcie: vcc3v3-minipcie-regulator
vcc3v3_ngff: vcc3v3-ngff-regulator

so i would drop it there...

so i end up with (including existing ones to compare):

vcc3v3_sys: vcc3v3-sys
vcc5v0_sys: vcc5v0-sys
pcie30_avdd0v9: pcie30-avdd0v9
pcie30_avdd1v8: pcie30-avdd1v8
vcc3v3_pi6c_05: vcc3v3-pi6c-05
vcc3v3_minipcie: vcc3v3-minipcie
vcc3v3_ngff: vcc3v3-ngff
vcc5v0_usb: vcc5v0_usb
vcc5v0_usb_host: vcc5v0-usb-host
vcc5v0_usb_otg: vcc5v0-usb-otg

is this ok?

maybe swap avdd* and pcie30 part to have voltage in front of function.

only these 3 new have the suffix:

vcc3v3_pi6c_05: vcc3v3-pi6c-05-regulator
vcc3v3_minipcie: vcc3v3-minipcie-regulator
vcc3v3_ngff: vcc3v3-ngff-regulator

so i would drop it there...

so i end up with (including existing ones to compare):

vcc3v3_sys: vcc3v3-sys
vcc5v0_sys: vcc5v0-sys
pcie30_avdd0v9: pcie30-avdd0v9
pcie30_avdd1v8: pcie30-avdd1v8
vcc3v3_pi6c_05: vcc3v3-pi6c-05
vcc3v3_minipcie: vcc3v3-minipcie
vcc3v3_ngff: vcc3v3-ngff
vcc5v0_usb: vcc5v0_usb
vcc5v0_usb_host: vcc5v0-usb-host
vcc5v0_usb_otg: vcc5v0-usb-otg

is this ok?

maybe swap avdd* and pcie30 part to have voltage in front of function.

I prefer all of them have regulator suffix. I think reasonable is also
to rename the old ones and then add new ones with suffix.

ok, will change these to add -regulator in name (not label). and then rename the others in separate Patch outside of the series.

so basicly here
-       pcie30_avdd0v9: pcie30-avdd0v9 {
+       pcie30_avdd0v9: pcie30-avdd0v9-regulator {
-       pcie30_avdd1v8: pcie30-avdd1v8 {
+       pcie30_avdd1v8: pcie30-avdd1v8-regulator {

how about the swapping of pcie30 and the avddXvY? In Schematic they are named PCIE30_AVDD_0V9 / PCIE30_AVDD_1V8, so better leave this?

avdd0v9-pcie30 will be more similar to the other regulators, but inconsistent with Schematic.

ok, will change these to add -regulator in name (not label). and then rename the others in separate Patch outside of the series.

so basicly here
-       pcie30_avdd0v9: pcie30-avdd0v9 {
+       pcie30_avdd0v9: pcie30-avdd0v9-regulator {
-       pcie30_avdd1v8: pcie30-avdd1v8 {
+       pcie30_avdd1v8: pcie30-avdd1v8-regulator {

how about the swapping of pcie30 and the avddXvY? In Schematic they are named PCIE30_AVDD_0V9 / PCIE30_AVDD_1V8, so better leave this?

avdd0v9-pcie30 will be more similar to the other regulators, but inconsistent with Schematic.

Does not matter to me - it is still a specific prefix, so whatever you
put there it's for you, not for me. Keeping something aligned to
schematic - even if not consistently named - makes sense to me.

now that the phy-driver changes got applied I'll just pick up the remaining
patches and do the node-name conversion while applying, so no need
to send another revision for it.

But of course feel free so send patches for converting the other regulator
names.

And I'm definitly preferring keeping close to schematic names :-)
