* regulator: rk808: make better use of the gpiod APIUwe Kleine-König2015-07-211-20/+12
| | | | | | | | | | | | | | | | The gpiod functions include variants for managed gpiod resources. Use it to simplify the remove function. As the driver handles a device node without a specification of dvs gpios just fine, additionally use the variant of gpiod_get exactly for this use case. This makes error checking more strict. As a third benefit this patch makes the driver use the flags parameter of gpiod_get* which will not be optional any more after 4.2 and so prevents a build failure when the respective gpiod commit is merged.

* regulator: rk808: fixed the overshoot when adjust voltageChris Zhong2015-07-201-12/+207
| | | | | | | | | | | | | | | | | | There is a overshoot in DCDC1/DCDC2, we have 2 method to workaround: 1st is use dvs pin to switch the voltage between value in BUCKn_ON_VSEL and BUCKn_DVS_VSEL. If DVS pin is inactive, the voltage of DCDC1/DCDC2 are controlled by BUCKn_ON_VSEL, when we pull dvs1/dvs2 pin to active, they would be controlled by BUCKn_DVS_VSEL. In this case, the ramp rate is same as the value programmed in BUCKn_RATE, and the fastest rate is 10mv/us. 2nd method is gradual adjustment, adjust the voltage to a target value step by step via i2c, each step is set to 100 mA. If you write the voltage directly using an i2c write the rk808 will always ramp as fast as it possibly can, about 100mv/us.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | The LDOs are documented in the rk808 datasheet to have a soft start time of 400us. Add that to the driver. If this time takes longer on a certain board the device tree should be able to override with "regulator-enable-ramp-delay". This fixes some dw_mmc probing problems (together with other patches posted to the mmc maiing lists) on rk3288.
