dbc5595540 regulator: core: Fix size limit of supply_map
Now the debugfs file supply_map has a size limit PAGE_SIZE and the user
can not see the whole content of regulator_map_list when it is larger
than this limit.

This patch uses seq_file instead to make sure supply_map shows the full
information of regulator_map_list.

Some regulators support get_voltage() and some support get_voltage_sel()

a get_voltage() operation.  Also do this if we've got get_voltage_sel()

062171973e regulator: core: Prioritise consumer mappings over regulator name
Currently, when looking up a regulator supply, the regulator name
takes priority over the consumer mappings. As there are a lot of
regulator names that are in fairly common use (VDD, MICVDD, etc.) this
can easily lead to obtaining the wrong supply, when a system contains
two regulators that share a name.

The explicit consumer mappings contain much less ambiguity as they
specify both a name and a consumer device. As such prioritise those if
one exists and only fall back to the regulator name if there are no
matching explicit mappings.

4b7f4958a3 regulator: da9061: BUCK and LDO regulator driver
Regulator support for the DA9061 is added into the DA9062 regulator driver.

The regulators for DA9061 differ from those of DA9062.
A new DA9061 enumeration list for the LDOs and Bucks supported by this
device is added. Regulator information added: the old regulator
information for DA9062 is renamed from local_regulator_info[] to
local_da9062_regulator_info[] and a new array is added to support
local_da9061_regulator_info[].

The probe() function switches on the da9062_compatible_types enumeration
and configures the correct da9062_regulator_info array and number of
regulator entries.

Kconfig is updated to reflect support for DA9061 and DA9062 regulators.

96e4f5232c regulator: palmas: Drop unnecessary static
Drop static on a local variable, when the variable is initialized before
any use, on every possible execution path through the function.

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@bad exists@
position p;
identifier x;
type T;
@@

static T x@p;
...
x = <+...x...+>

@@
identifier x;
expression e;
type T;
position p != bad.p;
@@

-static
 T x@p;
 ... when != x
     when strict
?x = e;
// </smpl>

There is no reduction in code size in this case, but the change does reduce
the size of the bss segment, containing uninitialized static data.

c90722b54a regulator: tps65023: Fix inverted core enable logic.
Commit 43530b69d7 ("regulator: Use
regmap_read/write(), regmap_update_bits functions directly") intended
to replace working inline helper functions with standard regmap
calls.  However, it also inverted the set/clear logic of the "CORE ADJ
Allowed" bit.  That patch was clearly never tested, since without that
bit cleared, the core VDCDC1 voltage output does not react to I2C
configuration changes.

This patch fixes the issue by clearing the bit as in the original,
correct implementation.  Note for stable back porting that, due to
subsequent driver churn, this patch will not apply on every kernel
version.
