Changes in v5:
- modify description for ssc and ext-refclk
- remove apb reset
- add rockchip_combphy_updatel()
- restyle

Changes in v4:
- restyle
- remove some minItems
- add more properties
- remove reset-names
- move #phy-cells
- add rockchip,rk3568-pipe-grf
- add rockchip,rk3568-pipe-phy-grf
- add devm_reset_control_array_get()
- remove clk structure
- change refclk DT parse
- change dev_err message
- add dot to phrase
- add ext_refclk variable
- add enable_ssc variable
- rename rockchip_combphy_param_write
- remove param_read
- replace rockchip-naneng-combphy driver name
- rename node name

Changes in v3:
- Using api devm_reset_control_get_optional_exclusive and dev_err_probe.
- Remove apb_rst.
- Redefine registers address.
- Move pipe_phy_grf0 to rk3568.dtsi

Changes in v2:
- Fix dtschema/dtc warnings/errors
- Using api devm_platform_get_and_ioremap_resource.

[PATCH v5 3/4] phy: rockchip: add naneng combo phy for RK3568

[Yifeng Zhao]

This patch implements a combo phy driver for Rockchip SoCs
with NaNeng IP block. This phy can be used as pcie-phy, usb3-phy,
sata-phy or sgmii-phy.

Changes in v5:
- add rockchip_combphy_updatel()
- restyle

Changes in v4:
- restyle
- add devm_reset_control_array_get()
- remove clk structure
- change refclk DT parse
- change dev_err message
- add dot to phrase
- add ext_refclk variable
- add enable_ssc variable
- rename rockchip_combphy_param_write
- remove param_read
- replace rockchip-naneng-combphy driver name

Changes in v3:
- Using api devm_reset_control_get_optional_exclusive and dev_err_probe.
- Remove apb_rst.
- Redefine registers address.

Changes in v2:
- Using api devm_platform_get_and_ioremap_resource.
- Modify rockchip_combphy_set_Mode.
- Add some PHY registers definition.

[PATCH v5 3/4] phy: rockchip: add naneng combo phy for RK3568

[Yifeng Zhao]

This patch implements a combo phy driver for Rockchip SoCs
with NaNeng IP block. This phy can be used as pcie-phy, usb3-phy,
sata-phy or sgmii-phy.

Changes in v5:
- add rockchip_combphy_updatel()
- restyle

Changes in v4:
- restyle
- add devm_reset_control_array_get()
- remove clk structure
- change refclk DT parse
- change dev_err message
- add dot to phrase
- add ext_refclk variable
- add enable_ssc variable
- rename rockchip_combphy_param_write
- remove param_read
- replace rockchip-naneng-combphy driver name

Changes in v3:
- Using api devm_reset_control_get_optional_exclusive and dev_err_probe.
- Remove apb_rst.
- Redefine registers address.

Changes in v2:
- Using api devm_platform_get_and_ioremap_resource.
- Modify rockchip_combphy_set_Mode.
- Add some PHY registers definition.

[PATCH v5 3/4] phy: rockchip: add naneng combo phy for RK3568

[Yifeng Zhao]

This patch implements a combo phy driver for Rockchip SoCs
with NaNeng IP block. This phy can be used as pcie-phy, usb3-phy,
sata-phy or sgmii-phy.

Changes in v5:
- add rockchip_combphy_updatel()
- restyle

Changes in v4:
- restyle
- add devm_reset_control_array_get()
- remove clk structure
- change refclk DT parse
- change dev_err message
- add dot to phrase
- add ext_refclk variable
- add enable_ssc variable
- rename rockchip_combphy_param_write
- remove param_read
- replace rockchip-naneng-combphy driver name

Changes in v3:
- Using api devm_reset_control_get_optional_exclusive and dev_err_probe.
- Remove apb_rst.
- Redefine registers address.

Changes in v2:
- Using api devm_platform_get_and_ioremap_resource.
- Modify rockchip_combphy_set_Mode.
- Add some PHY registers definition.

Re: [PATCH v5 4/4] arm64: dts: rockchip: add naneng combo phy nodes for rk3568

[Johan Jonker]

Hi Heiko, Yifeng,

Could you advise whether we should change the DT layout and driver a bit.
Some properties don't really fit to one particular phy node, so move
them to a parent node.

Maybe replace rockchip,sgmii-mac-sel by a node in phy 1 and 2 ??

Also there are two USB3.0 Controllers, one can use as USB3.0 OTG
Controller, another one can use as USB3.0 Host Controller only.
Yet properties are called: rockchip,dis-u3otg0-port,
rockchip,dis-u3otg1-port.
Maybe replace them by a node ??

Unknown capabilities of future (rk3588) Naneng versions (combined  host
and otg ??)

Maybe follow more in line with the phy-rockchip-inno-usb2.c and
phy-rockchip-usb.c drivers.

Could you confirm combo PHY on the RK3566 lacks the QSGMII/SGMII stuff?
(Lack of rk3566 TRM)

With so many differences maybe use separate compatible string and keep
the DT nodes completely apart.
(rockchip,rk3566-naneng-combphy, rockchip,rk3568-naneng-combphy)

Re: [PATCH v5 4/4] arm64: dts: rockchip: add naneng combo phy nodes for rk3568

[Johan Jonker]

Hi Heiko, Yifeng,

Could you advise whether we should change the DT layout and driver a bit.
Some properties don't really fit to one particular phy node, so move
them to a parent node.

Maybe replace rockchip,sgmii-mac-sel by a node in phy 1 and 2 ??

Also there are two USB3.0 Controllers, one can use as USB3.0 OTG
Controller, another one can use as USB3.0 Host Controller only.
Yet properties are called: rockchip,dis-u3otg0-port,
rockchip,dis-u3otg1-port.
Maybe replace them by a node ??

Unknown capabilities of future (rk3588) Naneng versions (combined  host
and otg ??)

Maybe follow more in line with the phy-rockchip-inno-usb2.c and
phy-rockchip-usb.c drivers.

Could you confirm combo PHY on the RK3566 lacks the QSGMII/SGMII stuff?
(Lack of rk3566 TRM)

With so many differences maybe use separate compatible string and keep
the DT nodes completely apart.

Re: [PATCH v5 4/4] arm64: dts: rockchip: add naneng combo phy nodes for rk3568

[Johan Jonker]

Hi Heiko, Yifeng,

Could you advise whether we should change the DT layout and driver a bit.
Some properties don't really fit to one particular phy node, so move
them to a parent node.

Maybe replace rockchip,sgmii-mac-sel by a node in phy 1 and 2 ??

Also there are two USB3.0 Controllers, one can use as USB3.0 OTG
Controller, another one can use as USB3.0 Host Controller only.
Yet properties are called: rockchip,dis-u3otg0-port,
rockchip,dis-u3otg1-port.
Maybe replace them by a node ??

Unknown capabilities of future (rk3588) Naneng versions (combined  host
and otg ??)

Maybe follow more in line with the phy-rockchip-inno-usb2.c and
phy-rockchip-usb.c drivers.

Could you confirm combo PHY on the RK3566 lacks the QSGMII/SGMII stuff?
(Lack of rk3566 TRM)

With so many differences maybe use separate compatible string and keep
the DT nodes completely apart.
(rockchip,rk3566-naneng-combphy, rockchip,rk3568-naneng-combphy)
