e227867f12 treewide: Fix typo in Documentation/DocBook
This patch fix spelling typo in Documentation/DocBook.
It is because .html and .xml files are generated by make htmldocs,
I have to fix a typo within the source files.

3e01c75a45 pfuze100-regulator: Fix of_node_get() parameter
Since commit d7857c42 (regulator: pfuze100: Use of_get_child_by_name) we get
the following probe failure:

pfuze100-regulator 1-0008: Full layer: 1, Metal layer: 0
pfuze100-regulator 1-0008: FAB: 0, FIN: 0
pfuze100-regulator 1-0008: regulators node not found
pfuze100-regulator: probe of 1-0008 failed with error -22

Now that of_get_child_by_name() is used we should adjust the device_node pointer
'np' to not get the parent node anymore.

regulators for cpu voltage scaling.

Since bypass and power gating modes are not configured

store bypass state to be restored when reenabling the

5c24d355dd regulator: ti-abb-regulator: do not open-code counting and access of dt array elements
Open coding the counting of elements in a dt-property is abstracted by the newly
introduced of_property_count_uXX_elems functions. Additionally the raw iteration
over the states element exposes the endian conversion and dtb-format details,
which according to Mark Rutland "would be nice to limit [...] to of_ helper
functions".

Thus change ti-abb-regulator to use the helper for element counting and
of_property_read_u32_index for retrieval of individual values.

This makes it possible to remove the raw access to the property entirely.

ebf6dad0de regulator: da9063: Bug fix when setting max voltage on LDOs 5-11
Bug fix to allow the setting of maximum voltage for certain LDOs.

What the bug is:

There is a problem caused by an invalid calculation of n_voltages
in the driver. This n_voltages value has the potential to be
different for each regulator.

The value for linear_min_sel is set as DA9063_V##regl_name#
which can be different depending upon the regulator. This is
chosen according to the following definitions in the DA9063
registers.h file:

DA9063_VLDO1_BIAS	0
DA9063_VLDO2_BIAS	0
DA9063_VLDO3_BIAS	0
DA9063_VLDO4_BIAS	0
DA9063_VLDO5_BIAS	2
DA9063_VLDO6_BIAS	2
DA9063_VLDO7_BIAS	2
DA9063_VLDO8_BIAS	2
DA9063_VLDO9_BIAS	3
DA9063_VLDO10_BIAS	2
DA9063_VLDO11_BIAS	2

The calculation for n_voltages is valid for LDOs whose BIAS value
is zero but this is not correct for those LDOs which have a
non-zero value.

What the fix is:

In order to take into account the non-zero linear_min_sel value which
is set for the regulators LDO5, LDO6, LDO7, LDO8, LDO9, LDO10 and
LDO11, the calculation for n_voltages should take into account the
missing term defined by DA9063_V##regl_name#.

This will in turn allow the core constraints calculation to set the
maximum voltage limits correctly and therefore allow users to apply
the maximum expected voltage to all of the LDOs.
