Tested on a rk3288 sdk board as logic voltage regulator. Changes in v4: Adviced by Doug Anderson - improve kconfig - add const for desc structure Changes in v3: Adviced by Doug Anderson - Make Kconfig & Makefile alphabetical - remove pwm_reg_period from pwm_regulator_data - modify the calculation in pwm_regulator_set_voltage_sel - add length validity check Adviced by Doug Anderson - update the Example Changes in v2: Adviced by Lee Jones - rename the file - remove all the prefix st_ - add depend on PWM in Kconfig Adviced by Lee Jones - rename the documentation Adviced by Doug Anderson - update the example Adviced by Mark Rutland - remove pwm-reg-period Chris Zhong (2): regulator: st-pwm: get voltage and duty table from dts dt-bindings: add devicetree bindings for st-pwm regulator .../bindings/regulator/pwm-regulator.txt | 27 +++ drivers/regulator/Kconfig | 13 +- drivers/regulator/Makefile | 2 +- drivers/regulator/pwm-regulator.c | 197 ++++++++++++++++++++ drivers/regulator/st-pwm.c | 190 ------------------- 5 files changed, 232 insertions(+), 197 deletions(-) create mode 100644 Documentation/devicetree/bindings/regulator/pwm-regulator.txt create mode 100644 drivers/regulator/pwm-regulator.c delete mode 100644 drivers/regulator/st-pwm.c -- 1.7.9.5
