|
|
The regulator_init_complete_work logic defers the cleanup for an
arbitrary 30 seconds of time to allow modules loaded by userland
to start.
This arbitrary timeout is similar to the
driver_deferred_probe_timeout value, and its been suggested we
align these so users have a method to extend the timeouts as
needed.
So this patch changes the logic to use the
driver_deferred_probe_timeout value for the delay value if it
is set (using a delay of 0 if it is not).

There maybe an overshoot, when disabling, then re-enabling vrefbuf
too quickly. VREFBUF is used by ADC/DAC on some boards. When re-enabling
too quickly, an overshoot on the reference voltage make the conversions
inaccurate for a short period of time.
- Don't put the VREFBUF in HiZ when disabling, to force an active
discharge.
- Enforce a 1ms OFF/ON delay

Few ROHM PMICs allow setting the voltage states for different system states
like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific
mechanisms. bd718x7 driver implemented device-tree parsing functions for
these state specific voltages. The parsing functions can be re-used by
other ROHM chip drivers like bd71828. Split the generic functions from
bd718x7-regulator.c to rohm-regulator.c and export them for other modules
to use.

Do device matching using the platform_device_id instead of using

`cat /sys/kernel/debug/regulator/regulator_summary` ends on a deadlock
when you have a voltage controlled regulator (vctrl).
The problem is that the vctrl_get_voltage() and vctrl_set_voltage() calls the
regulator_get_voltage() and regulator_set_voltage() and that will try to lock
again the dependent regulators (the regulator supplying the control voltage).
Fix the issue by exporting the unlocked version of the regulator_get_voltage()
and regulator_set_voltage() API so drivers that need it, like the voltage
controlled regulator driver can use it.

ROHM BD71828 is a power management IC containing 7 bucks and 7 LDOs. Bucks
1,2,6 and 7 can be assigned to a regulator group controlled by run-levels.
Eg. Voltages and enable/disable statuses for specific run-levels (run0 to
run3) can be set via register interface and run level changes can then be
done either via I2C or GPIO.
This initial commit does not support assigning bucks to be controlled via
run-levels but only allows them to be individually controlled.
LDO5 voltage can also be controlled by GPIO2 pin and register interfaces
but this driver only supports the control via register.

RK808 can leverage a couple of GPIOs to tweak the ramp rate during DVS
(Dynamic Voltage Scaling). These GPIOs are entirely optional but a
dev_warn() appeared when cleaning this driver to use a more up-to-date
gpiod API. At least reduce the log level to 'info' as it is totally
fine to not populate these GPIO on a hardware design.
This change is trivial but it is worth not polluting the logs during
bringup phase by having real warnings and errors sorted out
correctly.

Inside machine_constraints_voltage() a loop is in charge of verifying that
each of the defined voltages are within the configured constraints and
that those constraints are in fact compatible with the available voltages'
list.
When the registered regulator happens to be defined with a wide range of
possible voltages the above O(n) loop can be costly.
Moreover since this behaviour is triggered during the registration process,
it means also that it can be easily triggered at probe time, slowing down
considerably some module loading.
On the other side if such wide range of voltage values happens to be also
continuous and without discontinuity of any kind, the above potentially
cumbersome operation is also useless.
For these reasons, avoid such .list_voltage poll loop when regulator is
described as 'continuous_voltage_range' as is, indeed, similarly already
done inside regulator_is_supported_voltage().

clean:

We add a variable to record the failure of device_register() and
move put_device() down a bit to avoid the above issues.

This is caused by dereferencing 'rdev' after put_device() in
the _regulator_get()/_regulator_put() functions.
This patch just moves the put_device() down a bit to avoid the
issue.

Tell the regulator framework to retrieve regulator init
data from the 'regulator' subnode, or from the parent mfd
device's platform data.
Example:
i2c0 {
tps61052@33 {
compatible = "ti,tps61052";
reg = <0x33>;
regulator {
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
regulator-always-on;
};
};
};
