This patch adds support for TPS65912 PMIC regulators.
The regulators set consists of 4 DCDCs and 10 LDOs. The output
voltages are configurable and are meant to supply power to the
main processor and other components.Signed-off-by: Andrew F. Davis

Add REGULATOR_LINEAR_RANGE macro and convert regulator drivers to use it.
Signed-off-by: Axel Lin
Signed-off-by: Mark Brown -
linear ranges means each range has linear voltage settings.
So we can calculate max_uV for each linear range in regulator core rather than
set the max_uV field in drivers.Signed-off-by: Axel Lin

The ldo voltage table is composed of linear ranges.
Below is the equation in original code (tps65912_vsel_to_uv_ldo):
0 ... 32: uv = vsel * 25000 + 800000;
33 ... 60: uv = (vsel - 32) * 50000 + 1600000;
= (vsel -33) * 50000 + 1650000;
61 ...63: uv = (vsel - 60) * 100000 + 3000000;
= (vsel - 61) * 100000 + 3100000;This patch converts tps65912_ops_ldo to use multiple linear ranges APIs.

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.For the drivers that don't need the delay, don't need to include linux/delay.h.
This patch removes the unneeded include of linux/delay.h in regulator drivers.Signed-off-by: Axel Lin

Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.Signed-off-by: Mark Brown

commit 42b5ef "regulator: tps65912: Use simple equations to get register address"
uses tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register
and tps65912_get_ldo_sel_register.Now tps65912_set_voltage_dcdc_sel and tps65912_set_voltage_ldo_sel has exactly
the same implementation. Merge them to tps65912_set_voltage_sel function.Signed-off-by: Axel Lin

and tps65912_get_ldo_sel_register.Signed-off-by: Axel Lin

With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.Signed-off-by: Rajendra Nayak

Currently we define TPS65912_MAX_REG_ID as TPS65912_REG_LDO_10,
but TPS65912_REG_LDO_10 is not defined at all.
( It looks like a typo of TPS65912_REG_LDO10 )
Currently, TPS65912_MAX_REG_ID is not used in this driver,
it is safe to just remove it.Signed-off-by: Axel Lin
