Commit c368e5fc "regulator: fixed:

the fixed regulator, because an earlier commit

for the fixed-voltage special case to that function. This patch

These patches add the ability to create an alternative device on which
a lookup for a certain supply should be conducted.

A common use-case for this would be devices that are logically
represented as a collection of drivers within Linux but are are
presented as a single device from device tree. It this case it is
necessary for each sub device to locate their supply data on the main
device.

The device tree binding of Palmas regulator driver says as:

palmas_pmis {
	compatible = "ti,palmas-pmic";
	...
	regulators {
		...
	}
};

In this "regulators" subnode is expected to be part of parent node, not
the outside of parent node. Hence to get the regulator node, the correct
call is of_get_child_by_name() rather than of_find_node_by_name() which
actually searches the "regulators" node from the parent node to end of DTS
file.

Fix off-by-one in the equation to calculate max_uV and also adjust the _min_uV
setting accordingly.

For LDOs:
The voltage select bits set the LDO output voltage 0.825V...3.3V, 25mV steps
  ....00h : LDO off
  01h-24h : V_LDO4 = 0.8V + ldo4_vsel * 25mV
                   = 0.825V + (ldo4_vsel - 1h) * 25mV
  25h-3Fh : do not use
  40h-7Fh : V_LDO4 = 1.725V + (ldo4_vsel - 40h) * 25mV

For SD2345:
The voltage select bits set the DC/DC output voltage level and power the DC/DC
converter down.
  ....00h : DC/DC powered down
  01h-40h : V_SD2 = 0.6V + sd2_vsel * 12.5mV
                  = 0.6125V + (sd2_vsel - 1h) * 12.5mV
  41h-70h : V_SD2 = 1.4V + (sd2_vsel - 40h) * 25mV
                  = 1.425V + (sd2_vsel - 41h) * 25mV
  71h-7Fh : V_SD2 = 2.6V + (sd2_vsel - 70h) * 50mV
                  = 2.65V + (sd2_vsel - 71h) * 50mV

Note, the third entry in as3722_sd2345_ranges is wrong in current code.
Fix it based on the datasheet.
