b8b27a44dd regulator: remove unnecessary of_node_get() to parent
These of_node_get() were added to balance refcount decrements inside of
of_find_node_by_name().
See: commit c92f5dd2c4 ("regulator: Add missing of_node_put()")

However of_find_node_by_name() was then replaced by of_get_child_by_name(),
which doesn't call of_node_put() against its input parameter.

So, need to remove these unnecessary of_node_get() calls.

4ae1ff7fe8 regulator: tps65910: get regulators node from parent node only
As per the devicetree binding document of TPS65910, the "regulators"
subnode should be under the parent node, not 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 searches
the "regulators" node from the parent node to end of DTS file.

9fa8175f0f regulator: tps65910: Convert to use regulator_map_voltage_ascend
All regulators have ascendant voltage list in this driver.
Some regulators have more than 200 supported voltages.
e.g.
For TPS65910_REG_VDD1 and TPS65910_REG_VDD2:
n_voltages = VDD1_2_NUM_VOLT_FINE * VDD1_2_NUM_VOLT_COARSE
           = 73 * 3
           = 219

Thus it worth converting to regulator_map_voltage_ascend rather than use
default regulator_map_voltage_iterate.

For consistent, convert all regulators to regulator_map_voltage_ascend.

of_find_node_by_name() returns a node pointer with refcount incremented, use
of_node_put() on it when done.

of_find_node_by_name() will call of_node_put() against from parameter,
thus we also need to call of_node_get(from) before calling
of_find_node_by_name().

08337fdac2 regulator: tps65910: Fix using wrong dev argument for calling of_regulator_match
The dev parameter is the device requesting the data.
In this case it should be &pdev->dev rather than pdev->dev.parent.

The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(),
which means this fixes a memory leak because the memory is allocated every time
probe() is called, thus it should be freed when this driver is unloaded.

Recent change in the core driver to get the maximum voltage
is based on the (n_voltages -1) steps of voltage.
For the tps65910, the (n_voltages -1)th step voltage is

This function direct maps the datasheet and adjust the
first few steps for initial voltage as per datasheet,
and hence initialize the n_voltages based on datasheet.

f6442aa0b5 regulator: tps65910: Remove unused min_uV and max_uV from struct tps_info
The min_uV and max_uV fields of struct tps_info are not used in the code.
For the case voltage_table is provided, the min_uV and max_uV are the same
values as volt_table[0] and volt_table[n_voltages -1].
For the case voltage_table is not available, having the min_uV and max_uV seems
misleading. Current code uses equations to get the voltage value in this case,
but these equations do not use the min_uV and max_uV fields of struct tps_info.

Thus this patch removes the min_uV and max_uV fields from struct tps_info.

6c9eeb0f5c regulator: Remove unneeded include of linux/delay.h from regulator drivers
All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.

For the drivers that don't need the delay, don't need to include linux/delay.h.
This patch removes the unneeded include of linux/delay.h in regulator drivers.

c172708d38 regulator: core: Use a struct to pass in regulator runtime configuration
Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.

The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

d15d76448b regulator: Updates for 3.4
This has been a fairly quiet release from a regulator point of view, the
 only real framework features added were devm support and a convenience
 helper for setting up fixed voltage regulators.
 
 We also added a couple of drivers (but will drop the BQ240022 driver via
 the arm-soc tree as it's been replaced by the more generic
 gpio-regulator driver) and Axel Lin continued his relentless and
 generally awesome stream of fixes and cleanups.

18039e0f16 regulator: tps65910: Provide settling time for DCDC voltage change
Settling time is require when there is dcdc rail's voltage change.
Returning proper delay time for dcdc voltage change to settle down
the output voltage to new value.
