2022-09-20phy: qcom-qmp-ufs: shorten function prefixesJohan Hovold
The driver function prefix has gotten unnecessarily long and hurts readability. Shorten "qcom_qmp_phy_" to "qmp_" (which likely stands for "Qualcomm Multi PHY" or similar anyway).

2022-09-20phy: qcom-qmp: silence noisy probeJohan Hovold
Drivers should in general not log anything during unless there are errors. Drop the pointless registration info message from the QMP drivers.

Drop defines and enums that are unused since the QMP driver split. Signed-off-by: Johan Hovold <johan+linaro@kernel.org> Link: https://lore.kernel.org/r/20220907110728.19092-9-johan+linaro@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
2022-09-20phy: qcom-qmp-ufs: drop unused runtime PM implementationJohan Hovold
Drop the unused and incomplete runtime PM implementation, which was only used by USB PHYs before splitting the QMP driver. Note that the runtime PM was never disabled (and state restored) on driver unbind. This effectively reverts commit ac0d239936bd ("phy: qcom-qmp: Add support for runtime PM").

Drop the obsolete and misleading dual-lane comments which gave the impression that only combo PHYs have a second lane.

2022-07-07phy: qcom-qmp: split PCS_UFS V3 symbols to separate headerDmitry Baryshkov
Several registers defined in the PCS V3 namespace in reality belong to the PCS_UFS V3 register space. Move them to the separate header and rename them to explicitly mention PCS_UFS. While we are at it, correct one register in the msm8998_usb3_pcs_tbl table to use PCS register name.

The msm8996_ufs_serdes_tbl table contains write to QPHY_POWER_DOWN_CONTROL, however this register doesn't belong to the QSERDES register space.
