Hi,

+struct ufs_mtk_dev_params {
+	u32 pwm_rx_gear;        /* pwm rx gear to work in */
+	u32 pwm_tx_gear;        /* pwm tx gear to work in */
+	u32 hs_rx_gear;         /* hs rx gear to work in */
+	u32 hs_tx_gear;         /* hs tx gear to work in */
+	u32 rx_lanes;           /* number of rx lanes */
+	u32 tx_lanes;           /* number of tx lanes */
+	u32 rx_pwr_pwm;         /* rx pwm working pwr */
+	u32 tx_pwr_pwm;         /* tx pwm working pwr */
+	u32 rx_pwr_hs;          /* rx hs working pwr */
+	u32 tx_pwr_hs;          /* tx hs working pwr */
+	u32 hs_rate;            /* rate A/B to work in HS */
+	u32 desired_working_mode;
+};

As this is essentially identical to ufs_qcom_dev_params and ufs_hisi_dev_params etc.,
Maybe move it to ufshcd-platform.h in a short preparatory patch, so it can be reused?

Also, the vast majority of the code in these platform-dependent modules is pretty much the same.
I wonder if it can be shape to fit some standard form?
But this is out of scope of your series.

+/*
+ * PHY Adpater attributes

+#define PA_LOCALTXLCCENABLE         0x155E

Already in unipro.h

Thanks,
Avri
