of_parse_phandle() returns NULL either if the property name
itself does not exist or if it (exists and) does not
reference a valid phandle.
Giving out a warn like the one below (that the property references
an invalid phandle) can be confusing when the property itself
does not exist in the node.
Fix it with a more sensible message and make it a dev_dbg instead
of a dev_warn.Reported-by: Tomi Valkeinen

All the callback functions implementation for DCDCx and LDOx are very similar,
I think it is ok to use one tps6507x_pmic_ops for all LDOs and DCDCs.
This refactor removes a couple of duplicated code.Signed-off-by: Axel Lin

Anatop is an integrated regulator inside i.MX6 SoC.
There are 3 digital regulators which controls PU, CORE (ARM), and SOC.
And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB).
This patch adds the Anatop regulator driver.Signed-off-by: Nancy Chen

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

There is settling time for each rails when it is switched to
ON. Implementing enable time for returning proper settling time

The address of ctrl and sel registers can be calculated by simple equations.
This patch simplifies the implementation in tps65912_get_ctrl_register and
implements tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register
and tps65912_get_ldo_sel_register.Signed-off-by: Axel Lin

We actually clear LDO_ST_ON_BIT for standby mode in tps65910_set_mode.
Fix the logic in tps65910_get_mode.Supply state (EEPROM bits):
ST[1:0] = 00 : Off
ST[1:0] = 01 : On high power (ACTIVE)
ST[1:0] = 10 : Off
ST[1:0] = 11 : On low power (SLEEP)Signed-off-by: Axel Lin

Most callback functions implementation for tps65217_pmic_ldo234_ops and
tps65217_pmic_dcdc_ops are the same except the rid range checking.This patch uses tps65217_pmic_ops for all DCDCx, LDO2, LDO3, and LDO4.
And rework tps65217_pmic_set_voltage to make it can be called for
DCDCx, LDO2, LDO3, and LDO4.Signed-off-by: Axel Lin

This function finds the smallest voltage that falls within the specified range,
and then returns the selector. This rename makes the intention more clear.Also remove unneeded local variables min_vol and max_vol in s5m8767_set_voltage

Keep the rails OFF in sleep mode only when the rails are
controlled by external sleep control.
The devices tps65910 and tps65911, both has the sleep input.
The tps65911's sleep input is not same as tps65910's EN3 and hence
taking care of SLEEP input as separate external sleep control input.Signed-off-by: Laxman Dewangan

The reason we add *pdev in struct aat2870_regulator is to use it
to get a pointer to struct aat2870_data.
Save a pointer to struct aat2870_data instead of pdev in struct
aat2870_regulator, this change makes the intention more clear.Signed-off-by: Axel Lin
