phy: qcom-qmp: Add QMP V3 USB3 PHY support for SC7180

2020-05-19T05:51:01Z

Adding QMP v3 USB3 PHY support for SC7180. Adding only usb phy reset in the list to avoid reset of DP block.

phy: qcom-qmp: Ensure register indirection arrays initialized

2020-05-18T14:00:56Z

It's possible that struct qmp_phy_cfg->regs references an array that is smaller than the possible register lookups that is going to be performed, with the resulting out-of-bounds read resulting in undefined behavior. One such example is when during qcom_qmp_phy_com_init() performs a qphy_setbits() on entry QPHY_PCS_POWER_DOWN_CONTROL (i.e. 17) with msm8996_ufsphy_regs_layout only being 12 entries long. Solve this by inflating all "regs_layout" arrays to ensure that any remaining entries are zero-initialized, as expected by the code.

phy: qcom-qmp: Rename UFS PCS QMP v4 registers

The UFS QMP v4 PHY has a largely different register set versus USB and PCIe. Rename the register offsets to denote that the value is specific for the UFS PCS register.

The register map for SM8150 QMP USB SSPHY has moved QPHY_POWER_DOWN_CONTROL to a different offset. Allow for an offset in the register table to override default value if it is a DP capable PHY.

phy: qcom-snps: Add SNPS USB PHY driver for QCOM based SOCs

2020-05-05T05:14:04Z

This adds the SNPS FemtoPHY V2 driver used in QCOM SOCs. There are potentially multiple instances of this UTMI PHY on the SOC, all which can utilize this driver. The V2 driver will have a different register map compared to V1.
