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 V4: - This is newly added in V4, to add all the pm8008 common stuff. Changes in V5: - Changed the mfd node names from pm8008_chip to pm8008_infra and pm8008_ldo to pm8008_regulators as they re more appropriate. - Changed the compatible for pm8008@9 mfd node to differentiate from pm8008@8 node in driver. - Removed compatible for regulators node. - Removed reg property for LDOs and added in driver. arch/arm64/boot/dts/qcom/pm8008.dtsi | 46 ++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/pm8008.dtsi diff --git a/arch/arm64/boot/dts/qcom/pm8008.dtsi b/arch/arm64/boot/dts/qcom/pm8008.dtsi new file mode 100644 index 0000000..8e04983 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/pm8008.dtsi @@ -0,0 +1,46 @@ +// SPDX-License-Identifier: BSD-3-Clause +// Copyright (c) 2021, The Linux Foundation.
