2024-06-03phy: qcom-qmp: pcs: Add missing v6 N4 register offsetsAbel Vesa
The new X1E80100 SoC bumps up the HW version of QMP phy to v6 N4 for combo USB and DP PHY. Currently, the X1E80100 uses the pure V6 PCS register offsets, which are different. Add the offsets so the mentioned platform can be fixed later on. Add the new PCS offsets in a dedicated header file.

Currently, the x1e80100 uses pure V6 register offsets for DP part of the combo PHY. This hasn't been an issue because external DP is not yet enabled on any of the boards yet. But in order to enabled it, all these new V6 N4 register offsets are needed. So add them.

2024-04-07phy: qcom: m31: match requested regulator name with dt schemaGabor Juhos
According to the 'qcom,ipq5332-usb-hsphy.yaml' schema, the 5V supply regulator must be defined via the 'vdd-supply' property. The driver however requests for the 'vdda-phy' regulator which results in the following message when the driver is probed on a IPQ5018 based board with a device tree matching to the schema: qcom-m31usb-phy 5b000.phy: supply vdda-phy not found, using dummy regulator qcom-m31usb-phy 5b000.phy: Registered M31 USB phy This means that the regulator specified in the device tree never gets enabled. Change the driver to use the 'vdd' name for the regulator as per defined in the schema in order to ensure that the corresponding regulator gets enabled.

2024-04-06phy: qcom: qmp-combo: Fix register base for QSERDES_DP_PHY_MODEStephen Boyd
The register base that was used to write to the QSERDES_DP_PHY_MODE register was 'dp_dp_phy' before commit 815891eee668 ("phy: qcom-qmp-combo: Introduce orientation variable"). There isn't any explanation in the commit why this is changed, so I suspect it was an oversight or happened while being extracted from some other series. Oddly the value being 0x4c or 0x5c doesn't seem to matter for me, so I suspect this is dead code, but that can be fixed in another patch. It's not good to write to the wrong register space, and maybe some other version of this phy relies on this.

2024-04-06phy: qcom: qmp-combo: Fix VCO div offset on v3Stephen Boyd
Commit ec17373aebd0 ("phy: qcom: qmp-combo: extract common function to setup clocks") changed the offset that is used to write to DP_PHY_VCO_DIV from QSERDES_V3_DP_PHY_VCO_DIV to QSERDES_V4_DP_PHY_VCO_DIV. Unfortunately, this offset is different between v3 and v4 phys: #define QSERDES_V3_DP_PHY_VCO_DIV 0x064 #define QSERDES_V4_DP_PHY_VCO_DIV 0x070 meaning that we write the wrong register on v3 phys now. Add another generic register to 'regs' and use it here instead of a version specific define to fix this. This was discovered after Abhinav looked over register dumps with me from sc7180 Trogdor devices that started failing to light up the external display with v6.6 based kernels. It turns out that some monitors are very specific about their link clk frequency and if the default power on reset value is still there the monitor will show a blank screen or a garbled display. Other monitors are perfectly happy to get a bad clock signal.

2024-02-16phy: qcom-qmp-usb: fix v3 offsets dataDmitry Baryshkov
The MSM8996 platform has registers setup different to the rest of QMP v3 USB platforms. It has PCS region at 0x600 and no PCS_MISC region, while other platforms have PCS region at 0x800 and PCS_MISC at 0x600. This results in the malfunctioning USB host on some of the platforms. The commit f74c35b630d4 ("phy: qcom-qmp-usb: fix register offsets for ipq8074/ipq6018") fixed the issue for IPQ platforms, but missed the SDM845 which has the same register layout. To simplify future platform addition and to make the driver more future proof, rename qmp_usb_offsets_v3 to qmp_usb_offsets_v3_msm8996 (to mark its peculiarity), rename qmp_usb_offsets_ipq8074 to qmp_usb_offsets_v3 and use it for SDM845 platform.

Instead of incrementing the base of the global reg fields, which renders the second instance of the repeater broken due to wrong offsets, use regmap with base and offset. As for zeroing out the rest of the tuning regs, avoid looping though the table and just use the table as is, as it is already zero initialized.
