2018-08-28Revert "regulator: of: Use regulator-init-microvolt as early minimum"Finley Xiao
This reverts commit a4e0323d131b00b4d12cbbda42a7ea32dc5d72b6. If uboot needs a high cpu rate, the voltage should be set to a high value, and the minimal voltage of regulator will also be set to this value during kernel startup, so it will be failed to set voltage which is less than this value when consumers change voltage, for example pvtm. This patch add a new 'regulator-early-min-microvolt' property to limit the minimal voltage of regulator during kernel startup and it will no longer be restricted by uboot.

2018-03-22UPSTREAM: regulator: core: Add set_voltage_time opMatthias Kaehlcke
The new op is analogous to set_voltage_time_sel. It can be used by regulators which don't have a table of discrete voltages. The function returns the time for the regulator output voltage to stabilize after being set to a new value, in microseconds. If the op is not set a default implementation is used to calculate the delay. This change also removes the ramp_delay calculation in the PWM regulator, since the driver now uses the core code for the calculation of the delay.

2018-03-22UPSTREAM: regulator: core: Don't skip set_voltage_time when ramp delay disabledMatthias Kaehlcke
The current code assumes that only the ramp_delay is used to determine the time needed for the voltage to stabilize. This may be true for the calculation done by regulator_set_voltage_time_sel(), however regulators can implement their own set_voltage_time_sel() op which would be skipped if no ramp delay is specified. Remove the check in _regulator_do_set_voltage(), the functions calculating the ramp delay return 0 anyway when the ramp delay is not configured.

2018-02-05mfd: RK817 & RK809: Add new mfd driver for RK817 & RK809tony.xie
The RK817 & RK809 chip is a power management IC for multimedia and handheld devices. It contains the following components: - Regulators - RTC - Clkout - Pinctrl - Powerkey The RK817 & RK809 core driver is registered as a platform driver and provides communication through I2C with the host device for the different components. The following is the different between the RK817 and the RK809. 1、The dcdc-buck5 is a boost dcdc for RK817 and is a buck for RK809. 2、The RK817 have one switch but The Rk809 have two. 3、The RK817 have a charger and powerpatch function but RK809 not.
