This phy can be used as pcie-phy, usb3-phy, sata-phy or sgmii-phy.
Changes in v8:
- rename 'mode' to 'type'
- using devm_reset_control_array_get_exclusive
- move rockchip_combphy_set_mode into rockchip_combphy_init
Changes in v7:
- remove u3otg0_port_en, u3otg1_port_en and pipe_sgmii_mac_sel
- rename regs
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.
- Modify rockchip_combphy_set_Mode.
- Add some PHY registers definition.
- Move phy0 to rk3568.dtsi

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 v8:
- rename 'mode' to 'type'
- using devm_reset_control_array_get_exclusive
- move rockchip_combphy_set_mode into rockchip_combphy_init
Changes in v7:
- rename regs
- remove pipe_sgmii_mac_sel, u3otg0_port_en and u3otg1_port_en
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.

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 v8:
- rename 'mode' to 'type'
- using devm_reset_control_array_get_exclusive
- move rockchip_combphy_set_mode into rockchip_combphy_init
Changes in v7:
- rename regs
- remove pipe_sgmii_mac_sel, u3otg0_port_en and u3otg1_port_en
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.

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.

- rename regs
- remove pipe_sgmii_mac_sel, u3otg0_port_en and u3otg1_port_en
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:

The problem appears to be that patch 1 was applied incorrectly and the
compatibles ended up in the wrong section (the one requiring
'simple-mfd'). Patch 1 probably conflicts as my bot will just skip the
patch if it conflicts which is why this had a different error report.

Good Afternoon Rob,
This is fixed in the first patch of my rk356x dwc3 enablement series:
https://patchwork.kernel.org/project/linux-rockchip/patch/20220228135700.1089526-2-pgwipeout@gmail.com/
Very Respectfully,
Peter Geis

Good Afternoon Rob,
This is fixed in the first patch of my rk356x dwc3 enablement series:
