5b01bd11b7 regulator: palmas: fix typo in enable_reg calculation
When setting up .enable_reg for an SMPS regulator, presumably we should
call PALMAS_BASE_TO_REG(PALMAS_SMPS_BASE, ...) rather than using
LDO_BASE. This change makes the LCD panel and HDMI work again on the
NVIDIA Dalmore board anyway.

318dbb02b5 regulator: palmas: Fix SMPS enable/disable/is_enabled
We use regmap regulator ops to enable/disable and check if regulator
is enabled for various SMPS. However, these depend on valid
enable_reg, enable_mask and enable_value in regulator descriptor.

Currently we do not populate these for SMPS other than SMPS10, this
results in spurious results as regmap assumes that the values are
valid and ends up reading register 0x0 RTC:SECONDS_REG on Palmas
variants that do have RTC! To fix this, we update proper parameters
for the descriptor fields.

Further, we want to ensure the behavior consistent with logic
prior to commit dbabd624d4, where, once you do a set_mode,
enable/disable ensure the logic remains consistent and configures
Palmas to the configuration that we set with set_mode (since the
configuration register is common). To do this, we can rely on the
regulator core's regulator_register behavior where the regulator
descriptor pointer provided by the regulator driver is stored. (no
reallocation and copy is done). This lets us update the enable_value
post registration, to remain consistent with the mode we configure as
part of set_mode.

4251c2a670 Most of this is cleaning up various driver sysfs permissions so we can
re-add the perm check (we unified the module param and sysfs checks, but
 the module ones were stronger so we weakened them temporarily).
 
 Param parsing gets documented, and also "--" now forces args to be
 handed to init (and ignored by the kernel).
 
 Module NX/RO protections get tightened: we now set them before calling
 parse_args().
 
 Cheers,
 Rusty.

6b7f2d82d5 regulator: palmas: Fix SMPS list for 0V
get_voltage_sel reads from SMPS register - if the read selector value
is 0, the SMPS is actually disabled - So, this is in addition to the
ctrl_register that may also be used to enable/disable the SMPS.

The original logic(prior to commit dbabd624d4) used to be:
static int palmas_map_voltage_smps(struct regulator_dev *rdev,
               int min_uV, int max_uV)
<snip>
       if (min_uV == 0)
               return 0;

To handle this scenario, with the transition to regulator_list
implementation, we seem to have missed the data necessary to mark as
one of the valid entries as "0" 'disabled regulator' which results in
0 volts - So, stick with pre-existing logic.

Without this added to the list, palmas regulator driver,
on probe, attempts to setup constraints and in the case of
OMAP5uEVM, SMPS9 (which is mapped for 2v1 audio supply) fails in
regulator_list_voltage_linear_range mapping of '0', and as a fall back
of constraints not being applied, the entire regulator list is not
enumerated due to assumption that something system wide has gone bad
on with the PMIC.

2050afde19 regulator: as3722: Make 0 a valid selector
As of commit 064d5cd110 (regulator: core: Fix the init of DT defined
fixed regulators) the regulator core tries to query the current voltage
of a regulator when applying constraints. This exposes a bug in the
AS3722 regulator driver which fails to read the voltage of disabled
regulators. The reason is that the hardware is programmed to a selector
of 0, but none of the voltage tables include 0 as a valid selector. The
datasheets indicate that 0 is a valid selector when the regulators are
powered off.

To fix this, add a range including selector 0 to the voltage tables.

fd482a3e3e regulator: core: Disable unused regulators after deferred probing is done
regulator_init_complete does a scan of regulators which dont have
always-on or consumers are automatically disabled as being unused.
However, with deferred probing, late_initcall() is too soon to
declare a regulator as unused as the regulator itself might not
have registered due to defferal - Example: A regulator deffered due
to i2bus not available which in turn is deffered due to pinctrl
availability.

Since deferred probing is done in late_initcall(), do the cleanup of
unused regulators by regulator_init_complete in late_initcall_sync
instead of late_initcall.

e953583456 regulator: Don't disable unused regulators we don't have permission for
In the spirit of conservatism that governs our general approach to
permissions it is better if we don't touch regulators we weren't explicitly
given permissions to control. This avoids the need to explicitly specify
unknown regulators in DT as always on, if a regulator is not otherwise
involved in software control it can be omitted from the DT.

Regulators explicitly given constraints in DT still need to have an always
on constraint specified as before.

c0c14e6af9 regulator: ltc3589: Remove ltc3589_list_voltage_fixed function
When fixed_uV is set and n_voltage is 1, regulator core will return
rdev->desc->fixed_uV in regulator_get_voltage() and regulator_list_voltage().

Rename ltc3589_standby_regulator_ops to ltc3589_fixed_standby_regulator_ops,
this makes the code clear that the ops is for fixed voltage regulator.
