I would prefer to keep it as is for now, I think these configs are needed for the phy init, but I'm not sure these configs are all default correct after sw/hw reset/reboot and for all the SoC versions. > Reduce to only configure utmi_suspend_n and utmi_sel bits similar to > what is currently done on RK3399.

I don't understand this change for not much knowledge on utmi interface, any issue if we use the old config? If necessary, should send as a separate patch.

The bvalid_det_en/clr regs is related to interrupts, something this driver does not use, and in mainline linux they are only applied to otg/peripheral ports and not to all ports like in u-boot. My understanding is that the phy_sus reg is intented to control phy suspend mode, currently that is what the rk3399 and rk3588 variant is doing. However, for the other socs it tries to control phy suspend and also set values for other bits in the same hw reg. I think it is better to clean this up to make it work consistent and/or limit what bits we write now, instead of possibly introducing new issues because of the GRF fix in the first patch of this series. > > but I'm not sure these configs are all default correct after sw/hw > reset/reboot and for > > all the SoC versions. By default the phy seem to work for otg or host mode after a reset for all SoCs currently supported by this driver. I have tested this using host/otg/peripheral mode on RK3308, RK3328, RK3399, RK356x and RK3588. The missing RK3308 parts will be added in a separate series. > >> Reduce to only configure utmi_suspend_n and utmi_sel bits similar to >> what is currently done on RK3399. > I don't understand, you also remove configs for rk3399 in this patch, > isn't it? >> Also add missing clkout_ctl for RK3588. > This is necessary, would be better send as a separate patch. >> >> When enabled utmi_suspend_n is changed to normal mode and utmi_sel to >> use otg/host controller utmi interface to phy.

If I remember correctly I had some issue with otg when existing values where written to hw reg, and the working hw reset default value did not fully match the values defined for phy_sys on some port of rk3328 and/or rk356x. This patch fixes the inconsistent meaning/affect of phy_sus reg for all socs, instead of having different and possible unintended behaviour depending on the soc. > > If necessary, should send as a separate patch. Ensuring that the phy is configured in a similar way accross soc was the main intent for this patch, not sure how to split this in another way.

The USB2PHY regs already contain working default reset values for RK3328 and RK35xx as evidenced by the fact that this driver never has changed a single value for these SoCs. Reduce to only configure utmi_suspend_n and utmi_sel bits similar to what is currently done on RK3399. Also add missing clkout_ctl for RK3588. When enabled utmi_suspend_n is changed to normal mode and utmi_sel to use otg/host controller utmi interface to phy. When disabled utmi_suspend_n is changed to suspend mode and utmi_sel to use GRF utmi interface to phy.
