Signed-off-by: Satya Priya Reported-by: kernel test robot Reported-by: Dan Carpenter Reviewed-by: Stephen Boyd --- Changes in V15: - Removed unused variables from pm8008_regulator struct. - Replaced static_assert with BUILD_BUG_ON. Changes in V14: - Remove unused headers and debug prints. - Remove min_uv and max_uv from reg_data[] and set the min/max based on the voltage_range pointer. - In get_voltage_sel read voltage from hw and calculate selector instead of using selector from set_voltage. - Add errro check after regulator_list_voltage_linear_range(). - Use static_assert to make sure nldo_ranges & pldo_ranges doesn't become larger and we forget to update the pm8008_reg->rdesc.n_linear_ranges Changes in V13: - Added if check to avoid buffer overflow warnings. for (i = 0; i < ARRAY_SIZE(reg_data); i++) if (strstr(name, reg_data[i].name)) break; if (i == ARRAY_SIZE(reg_data)) { dev_err(dev, "Invalid regulator name %s\n", name); return -EINVAL; } - Removed unused headers. drivers/regulator/Kconfig | 9 ++ drivers/regulator/Makefile | 1 + drivers/regulator/qcom-pm8008-regulator.c | 242 ++++++++++++++++++++++++++++++ 3 files changed, 252 insertions(+) create mode 100644 drivers/regulator/qcom-pm8008-regulator.c diff --git a/drivers/regulator/Kconfig b/drivers/regulator/Kconfig index cbe0f96..2c6d9c2 100644 --- a/drivers/regulator/Kconfig +++ b/drivers/regulator/Kconfig @@ -925,6 +925,15 @@ config REGULATOR_PWM This driver supports PWM controlled voltage regulators.
