The UFS PHY found on SM6115/4250 has a lot of common registers with ufs phy v2,
even though in downstream it is named v3-660. Due to register similarity with
v2, the few extra registers that are needed are added as v2 registers.
The register values/sequences are taken from OnePlus repo [1].
[1] https://github.com/OnePlusOSS/android_kernel_oneplus_sm4250
v1: https://lkml.org/lkml/2021/8/5/235
v2: https://lkml.org/lkml/2021/8/13/889
Changes from v2:
- Suggested by Vinod
- the 6115 registers had a lot in common with v2 registers (and not v3, as
was initially assumed), so those were reused whenever possible, and new
regs were added along other v2 registers.
Changes from v1:
- Suggested by Vinod
- removed v3-660 constants for regs with same name and value as v3 regs

Add the tables and constants for init sequences for UFS QMP phy found in
SM4250/6115 SoC. The phy is a variation of the v2 phy, but is mistakenly
labeled as v3-660 in downstream sources.
QSERDES COM, RX, TX registers match fully existing v2 registers, with
a few additions. PCS registers don't have much in common, but there are
no clashes with existing ones so new registers were added to existing v2
PCS pack.

Add the tables and constants for init sequences for UFS QMP phy found in
SM4250/6115 SoC. The phy is a variation of the v2 phy, but is mistakenly
labeled as v3-660 in downstream sources.
QSERDES COM, RX, TX registers match fully existing v2 registers, with
a few additions. PCS registers don't have much in common, but there are
no clashes with existing ones so new registers were added to existing v2
PCS pack.
