Actually I believe SM8350 UFS PHY is on V5, as the internal IP revision shows 5.0.0. So IMO some of the below definitions should just be using the V5 macros for consistency with the ones I recently added for USB3. And like USB3 QMP, it seems we have mixed usage of V4/V5 macros in the sequence tables, mainly wherever the offsets are identical between IP revisions. Hope this doesn't turn out to be a maintenance nightmare... > --- > drivers/phy/qualcomm/phy-qcom-qmp.h | 27 +++++++++++++++++++++++++++ > 1 file changed, 27 insertions(+) > > diff --git a/drivers/phy/qualcomm/phy-qcom-qmp.h b/drivers/phy/qualcomm/phy-qcom-qmp.h > index dff7be5a1cc1..bba1d5e3eb73 100644 > --- a/drivers/phy/qualcomm/phy-qcom-qmp.h > +++ b/drivers/phy/qualcomm/phy-qcom-qmp.h > @@ -451,6 +451,7 @@ > #define QSERDES_V4_TX_RES_CODE_LANE_OFFSET_RX 0x40 > #define QSERDES_V4_TX_LANE_MODE_1 0x84 > #define QSERDES_V4_TX_LANE_MODE_2 0x88 > +#define QSERDES_V4_TX_LANE_MODE_3 0x8C > #define QSERDES_V4_TX_RCV_DETECT_LVL_2 0x9c > #define QSERDES_V4_TX_PWM_GEAR_1_DIVIDER_BAND0_1 0xd8 > #define QSERDES_V4_TX_PWM_GEAR_2_DIVIDER_BAND0_1 0xdC > @@ -459,6 +460,13 @@ > #define QSERDES_V4_TX_TRAN_DRVR_EMP_EN 0xb8 > #define QSERDES_V4_TX_PI_QEC_CTRL 0x104 > > +/* Only for SM8350 QMP V4 Phy TX offsets different from V4 */ > +#define QSERDES_SM8350_TX_PWM_GEAR_1_DIVIDER_BAND0_1 0x178 > +#define QSERDES_SM8350_TX_PWM_GEAR_2_DIVIDER_BAND0_1 0x17c > +#define QSERDES_SM8350_TX_PWM_GEAR_3_DIVIDER_BAND0_1 0x180 > +#define QSERDES_SM8350_TX_PWM_GEAR_4_DIVIDER_BAND0_1 0x184 > +#define QSERDES_SM8350_TX_TRAN_DRVR_EMP_EN 0xc0 These could be augmented to the V5 TX defintions? Although they are not present for USB, so not sure if you want to add "V5_UFS" to the prefix. But since they are at offsets past the end of the USB TX bank it should also be ok to share in the QSERDES_V5_TX namespace. > + > /* Only for QMP V4 PHY - RX registers */ > #define QSERDES_V4_RX_UCDR_FO_GAIN 0x008 > #define QSERDES_V4_RX_UCDR_SO_GAIN 0x014 > @@ -514,6 +522,24 @@ > #define QSERDES_V4_RX_DCC_CTRL1 0x1bc > #define QSERDES_V4_RX_VTH_CODE 0x1c4 > > +/* Only for SM8350 QMP V4 Phy RX offsets different from V4 */ > +#define QSERDES_SM8350_RX_RX_MODE_00_LOW 0x15c > +#define QSERDES_SM8350_RX_RX_MODE_00_HIGH 0x160 > +#define QSERDES_SM8350_RX_RX_MODE_00_HIGH2 0x164 > +#define QSERDES_SM8350_RX_RX_MODE_00_HIGH3 0x168 > +#define QSERDES_SM8350_RX_RX_MODE_00_HIGH4 0x16c > +#define QSERDES_SM8350_RX_RX_MODE_01_LOW 0x170 > +#define QSERDES_SM8350_RX_RX_MODE_01_HIGH 0x174 > +#define QSERDES_SM8350_RX_RX_MODE_01_HIGH2 0x178 > +#define QSERDES_SM8350_RX_RX_MODE_01_HIGH3 0x17c > +#define QSERDES_SM8350_RX_RX_MODE_01_HIGH4 0x180 > +#define QSERDES_SM8350_RX_RX_MODE_10_LOW 0x184 > +#define QSERDES_SM8350_RX_RX_MODE_10_HIGH 0x188 > +#define QSERDES_SM8350_RX_RX_MODE_10_HIGH2 0x18c > +#define QSERDES_SM8350_RX_RX_MODE_10_HIGH3 0x190 > +#define QSERDES_SM8350_RX_RX_MODE_10_HIGH4 0x194 > +#define QSERDES_SM8350_RX_DCC_CTRL1 0x1a8 These are identical to the "V5" offsets I had added for SM8350 USB.

Add the registers for few new registers found in SM8350. Also the UFS phy used in SM8350 seems to have different offsets than V4 phy, although it claims it is v4 phy, so add the new offsets with SM8350 tag instead of V4 tag.
