While at it also added RK8XX_DESC and RK8XX_DESC_SWITCH macros for the

we get a warning about the symbol not being referenced anywhere:

drivers/regulator/rk808-regulator.c:306:29: 'rk808_reg_ops_ranges' defined but not used

This removes the now-unused structure along with the

rk808_reg_ops_ranges.

Uwe Kleine-König a13eaf02e2 regulator: rk808: make better use of the gpiod API
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.

Chris Zhong bad47ad2ee regulator: rk808: fixed the overshoot when adjust voltage
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.

Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.
