PM8008 is an I2C controlled PMIC containing 7 LDO regulators. Add a PM8008 regulator driver to support PMIC regulator management via the regulator framework. Signed-off-by: Satya Priya --- Changes in V2: As per Mark's comments - Using regmap helpers for regulator enable/disable and is_enabled APIs - Changed pr_err to dev_err wherever possible. - Removed init_voltage property as it is not used. - Removed if check for registering LDOs - Other minor changes. Changes in V3: As per Stephen's comments, - Removed unused includes - Removed PM8008_MAX_LDO macro. - Removed pm8008_read/write APIs, using regmap_bulk_read/write APIs - Using le16_to_cpu/cpu_to_le16 APIs in pm8008_regulator_get/set_voltage - Consolidated all probe related functions into single probe function. - Added of_parse_cb call back and removed regulator-name matching loop. - Fixed other minor nits. Changes in V4: - Removed unused members like rdev and of_node from pm8008_regulator struct. - Replaced set_voltage with set_voltage_sel - Removed init_data configuration as it is not needed. - Removed few other unused assignments from probe Changes in V5: - Removed Compatible string. - Changed the probe function accordingly to probe LDOs using mfd driver. - Added max headrooms for LDOs and removed the part reading min-dropout from DT. - Added base reg values in the regulator_data struct instead of reading it from DT. drivers/regulator/Kconfig | 9 ++ drivers/regulator/Makefile | 1 + drivers/regulator/qcom-pm8008-regulator.c | 234 ++++++++++++++++++++++++++++++ 3 files changed, 244 insertions(+) create mode 100644 drivers/regulator/qcom-pm8008-regulator.c diff --git a/drivers/regulator/Kconfig b/drivers/regulator/Kconfig index 22503e4..4372ad7 100644 --- a/drivers/regulator/Kconfig +++ b/drivers/regulator/Kconfig @@ -925,6 +925,15 @@ config REGULATOR_PWM This driver supports PWM controlled voltage regulators.

Signed-off-by: Satya Priya --- Changes in V2: - As per Stephen's comments, replaced '_' with '-' for node names. Changes in V3: - Changed the regulator node names as l1, l2 etc - Changed "pm8008-regulators" to "regulators" - Changed "qcom,min-dropout-voltage" to "regulator-min-dropout-voltage-microvolt" Changes in V4: - Moved all common stuff to pm8008.dtsi and added board specific configurations here. Changes in V5: - Changed the node names as per pm8008.dtsi - Moved supply nodes to chip level (mfd node). - Removed the regulator-mindropout property. arch/arm64/boot/dts/qcom/sc7280-idp.dtsi | 66 ++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sc7280-idp.dtsi b/arch/arm64/boot/dts/qcom/sc7280-idp.dtsi index ecbf2b8..371ad19 100644 --- a/arch/arm64/boot/dts/qcom/sc7280-idp.dtsi +++ b/arch/arm64/boot/dts/qcom/sc7280-idp.dtsi @@ -263,6 +263,62 @@ }; }; +&i2c1 { + #address-cells = <1>; + #size-cells = <0>; + status = "okay"; + + #include "pm8008.dtsi" +}; + +&pm8008_infra { + pinctrl-names = "default"; + pinctrl-0 = <&pm8008_active>; +}; + +&pm8008_regulators { + vdd_l1_l2-supply = <&vreg_s8b_1p2>; + vdd_l3_l4-supply = <&vreg_s1b_1p8>; + vdd_l5-supply = <&vreg_bob>; + vdd_l6-supply = <&vreg_bob>; + vdd_l7-supply = <&vreg_bob>; +}; + +&pm8008_l1 { + regulator-min-microvolt = <950000>; + regulator-max-microvolt = <1300000>; +}; + +&pm8008_l2 { + regulator-min-microvolt = <950000>; + regulator-max-microvolt = <1250000>; +}; + +&pm8008_l3 { + regulator-min-microvolt = <1650000>; + regulator-max-microvolt = <3000000>; +}; + +&pm8008_l4 { + regulator-min-microvolt = <1504000>; + regulator-max-microvolt = <1600000>; +}; + +&pm8008_l5 { + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3000000>; +}; + +&pm8008_l6 { + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3000000>; +}; + +&pm8008_l7 { + regulator-min-microvolt = <3000000>; + regulator-max-microvolt = <3544000>; +}; + &qfprom { vcc-supply = <&vreg_l1c_1p8>; }; @@ -375,6 +431,16 @@ drive-strength = <2>; }; +&pm8350c_gpios { + pm8008_active: pm8008_active { + pins = "gpio4"; + function = "normal"; + bias-disable; + output-high; + power-source = <0>; + }; +}; + &qspi_cs0 { bias-disable; };
