In this change we add support to the generic PHY framework.
Two UFS phys are implemented:
qmp-20nm and qmp-28nm.
Also, the files in this change implement the UFS HW (controller & PHY)
specific behavior in Qualcomm chips.
Relocation of a few header files is needed in order to expose routines
and data structures between PHY driver and UFS driver

+* QCOM Universal Flash Storage (UFS) PHY
+
+UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
+Each UFS PHY node should have its own node.
+
+To bind UFS PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS PHY node.
+
+Required properties:
+- compatible : compatible list, contains "qcom,ufs-phy-qmp-28nm"
+ or "qcom,ufs-phy-qmp-20nm" according to the relevant
+ phy in use
+- reg : <registers mapping>
+- #phy-cells : This property shall be set to 0
+- vdda-phy-supply : phandle to main PHY supply for analog domain
+- vdda-pll-supply : phandle to PHY PLL and Power-Gen block power supply
+
+Optional properties:
+- vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
+- vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply
+
+Example:
+
+ ufsphy1: ufsphy@0xfc597000 {
+ compatible = "qcom,ufs-phy-qmp-28nm";
+ reg = <0xfc597000 0x800>;
+ #phy-cells = <0>;
+ vdda-phy-supply = <&pma8084_l4>;
+ vdda-pll-supply = <&pma8084_l12>;
+ vdda-phy-max-microamp = <50000>;
+ vdda-pll-max-microamp = <1000>;
+ };
+
+ ufshc@0xfc598000 {
+ ...
+ phys = <&ufsphy1>;
+ };

In this change we add support to the generic PHY framework.
Two UFS phys are implemented:
qmp-20nm and qmp-28nm.
Also, the files in this change implement the UFS HW (controller & PHY)
specific behavior in Qualcomm chips.
Relocation of a few header files is needed in order to expose routines
and data structures between PHY driver and UFS driver

+* QCOM Universal Flash Storage (UFS) PHY
+
+UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
+Each UFS PHY node should have its own node.
+
+To bind UFS PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS PHY node.
+
+Required properties:
+- compatible : compatible list, contains "qcom,ufs-phy-qmp-28nm"
+ or "qcom,ufs-phy-qmp-20nm" according to the relevant
+ phy in use
+- reg : <registers mapping>
+- #phy-cells : This property shall be set to 0
+- vdda-phy-supply : phandle to main PHY supply for analog domain
+- vdda-pll-supply : phandle to PHY PLL and Power-Gen block power supply
+
+Optional properties:
+- vdda-phy-max-microamp : specifies max. load that can be drawn from phy supply
+- vdda-pll-max-microamp : specifies max. load that can be drawn from pll supply
+
+Example:
+
+ ufsphy1: ufsphy@0xfc597000 {
+ compatible = "qcom,ufs-phy-qmp-28nm";
+ reg = <0xfc597000 0x800>;
+ #phy-cells = <0>;
+ vdda-phy-supply = <&pma8084_l4>;
+ vdda-pll-supply = <&pma8084_l12>;
+ vdda-phy-max-microamp = <50000>;
+ vdda-pll-max-microamp = <1000>;
+ };
+
+ ufshc@0xfc598000 {
+ ...
+ phys = <&ufsphy1>;
+ };

+ * As part of UFS power management, UFS link would be put in hibernate
+ * and UFS device would be put in SLEEP mode as part of runtime/system
+ * suspend callback. But when system goes into suspend with VDD
+ * minimization, UFS PHY states are being reset which means UFS link
+ * hibernate exit command on system resume would fail.
+ * If this quirk is enabled then above issue is workaround by saving
+ * the UFS PHY state information before system goes into suspend and
+ * restoring the saved state information during system resume but
+ * before executing the hibern8 exit command.
+ * Note that this quirk will help restoring the PHY state if even when
+ * link in not kept in hibern8 during suspend.
+ *
+ * Here is the list of steps to save/restore the configuration:
+ * Before entering into system suspend:
+ * 1. Read Critical PCS SWI Registers + less critical PHY CSR
+ * 2. Read RMMI Attributes
+ * Enter into system suspend
+ * After exiting from system suspend:
+ * 1. Set UFS_PHY_SOFT_RESET bit in UFS_CFG1 register of the UFS
+ * Controller
+ * 2. Write 0x01 to the UFS_PHY_POWER_DOWN_CONTROL register in the
+ * UFS PHY
+ * 3. Write back the values of the PHY SWI registers
+ * 4. Clear UFS_PHY_SOFT_RESET bit in UFS_CFG1 register of the UFS
+ * Controller
+ * 5. Write 0x01 to the UFS_PHY_PHY_START in the UFS PHY. This will
+ * start the PLL calibration and bring-up of the PHY.
+ * 6. Write back the values to the PHY RMMI Attributes

Subject: [PATCH v4] scsi: ufs: add support of generic PHY framework in
Qualcomm MSM chips
In this change we add support to the generic PHY framework.
Two UFS phys are implemented:
qmp-20nm and qmp-28nm.
Also, the files in this change implement the UFS HW (controller & PHY)
specific behavior in Qualcomm chips.
Relocation of a few header files is needed in order to expose routines
and data structures between PHY driver and UFS driver

+* QCOM Universal Flash Storage (UFS) PHY
+
+UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
+Each UFS PHY node should have its own node.
+
+To bind UFS PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS PHY node.
+
+Required properties:
+- compatible : compatible list, contains "qcom,ufs-phy-qmp-28nm"
+ or "qcom,ufs-phy-qmp-20nm" according to the relevant
+ phy in use
+- reg : <registers mapping>
+- #phy-cells : This property shall be set to 0
+- vdda-phy-supply : phandle to main PHY supply for analog domain
+- vdda-pll-supply : phandle to PHY PLL and Power-Gen block power supply
+
+Optional properties:
+- vdda-phy-max-microamp : specifies max. load that can be drawn from phy
supply
+- vdda-pll-max-microamp : specifies max. load that can be drawn from pll
supply
+
+Example:
+
+ ufsphy1: ufsphy@0xfc597000 {
+ compatible = "qcom,ufs-phy-qmp-28nm";
+ reg = <0xfc597000 0x800>;
+ #phy-cells = <0>;
+ vdda-phy-supply = <&pma8084_l4>;
+ vdda-pll-supply = <&pma8084_l12>;
+ vdda-phy-max-microamp = <50000>;
+ vdda-pll-max-microamp = <1000>;
+ };
+
+ ufshc@0xfc598000 {
+ ...
+ phys = <&ufsphy1>;
+ };

+ * hibernate exit command on system resume would fail.
+ * If this quirk is enabled then above issue is workaround by saving

+ * restoring the saved state information during system resume but
+ * before executing the hibern8 exit command.
+ * Note that this quirk will help restoring the PHY state if even
when

+ *
+ * Here is the list of steps to save/restore the configuration:
+ * Before entering into system suspend:
+ * 1. Read Critical PCS SWI Registers + less critical PHY CSR
+ * 2. Read RMMI Attributes
+ * Enter into system suspend
+ * After exiting from system suspend:

+ * 2. Write 0x01 to the UFS_PHY_POWER_DOWN_CONTROL register in
the
+ * UFS PHY
+ * 3. Write back the values of the PHY SWI registers
+ * 4. Clear UFS_PHY_SOFT_RESET bit in UFS_CFG1 register of the
UFS
+ * Controller
+ * 5. Write 0x01 to the UFS_PHY_PHY_START in the UFS PHY. This
will

Subject: [PATCH v4] scsi: ufs: add support of generic PHY framework in
Qualcomm MSM chips
In this change we add support to the generic PHY framework.
Two UFS phys are implemented:
qmp-20nm and qmp-28nm.
Also, the files in this change implement the UFS HW (controller & PHY)
specific behavior in Qualcomm chips.
Relocation of a few header files is needed in order to expose routines
and data structures between PHY driver and UFS driver

+* QCOM Universal Flash Storage (UFS) PHY
+
+UFSPHY nodes are defined to describe on-chip UFS PHY hardware macro.
+Each UFS PHY node should have its own node.
+
+To bind UFS PHY with UFS host controller, the controller node should
+contain a phandle reference to UFS PHY node.
+
+Required properties:
+- compatible : compatible list, contains "qcom,ufs-phy-qmp-28nm"
+ or "qcom,ufs-phy-qmp-20nm" according to the relevant
+ phy in use
+- reg : <registers mapping>
+- #phy-cells : This property shall be set to 0
+- vdda-phy-supply : phandle to main PHY supply for analog domain
+- vdda-pll-supply : phandle to PHY PLL and Power-Gen block power supply
+
+Optional properties:
+- vdda-phy-max-microamp : specifies max. load that can be drawn from phy
supply
+- vdda-pll-max-microamp : specifies max. load that can be drawn from pll
supply
+
+Example:
+
+ ufsphy1: ufsphy@0xfc597000 {
+ compatible = "qcom,ufs-phy-qmp-28nm";
+ reg = <0xfc597000 0x800>;
+ #phy-cells = <0>;
+ vdda-phy-supply = <&pma8084_l4>;
+ vdda-pll-supply = <&pma8084_l12>;
+ vdda-phy-max-microamp = <50000>;
+ vdda-pll-max-microamp = <1000>;
+ };
+
+ ufshc@0xfc598000 {
+ ...
+ phys = <&ufsphy1>;
+ };

+ * As part of UFS power management, UFS link would be put in
hibernate
+ * and UFS device would be put in SLEEP mode as part of
runtime/system
+ * suspend callback. But when system goes into suspend with VDD
+ * minimization, UFS PHY states are being reset which means UFS link
+ * hibernate exit command on system resume would fail.
+ * If this quirk is enabled then above issue is workaround by saving
+ * the UFS PHY state information before system goes into suspend and
+ * restoring the saved state information during system resume but
+ * before executing the hibern8 exit command.
+ * Note that this quirk will help restoring the PHY state if even
when
+ * link in not kept in hibern8 during suspend.
+ *
+ * Here is the list of steps to save/restore the configuration:
+ * Before entering into system suspend:
+ * 1. Read Critical PCS SWI Registers + less critical PHY CSR
+ * 2. Read RMMI Attributes
+ * Enter into system suspend
+ * After exiting from system suspend:
+ * 1. Set UFS_PHY_SOFT_RESET bit in UFS_CFG1 register of the
UFS
+ * Controller
+ * 2. Write 0x01 to the UFS_PHY_POWER_DOWN_CONTROL register in
the
+ * UFS PHY
+ * 3. Write back the values of the PHY SWI registers
+ * 4. Clear UFS_PHY_SOFT_RESET bit in UFS_CFG1 register of the
UFS
+ * Controller
+ * 5. Write 0x01 to the UFS_PHY_PHY_START in the UFS PHY. This
will
+ * start the PLL calibration and bring-up of the PHY.
+ * 6. Write back the values to the PHY RMMI Attributes
