2023-01-12phy: qcom-qmp-ufs: split UFS-specific v2 PCS registers to a separate headerDmitry Baryshkov4-20/+30
Follow other QMP headers, split and rename UFS-specific PCS registers to ease comparing regs differences. Signed-off-by: Dmitry Baryshkov <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Vinod Koul <[email protected]>
2023-01-12phy: qcom-qmp-pcie-msm8996: rework regs layout arraysDmitry Baryshkov1-3/+3
Use symbolic names for the values inside reg layout arrays. New register names are added following the PCS register layout that is used by the particular PHY. Note: ipq8074 tables appear to use a mixture of v2 and v3 registers. This might need additional fixes.

The source clock for the reference clock is not used by the PHY directly and should not be described by the devicetree (instead this relationship should be modelled in the clock driver).

The DP_PHY registers have erroneously been referred to as "PCS" registers since DisplayPort support was added to the QMP drivers (including in the devicetree binding).
