Subject: [PATCH v5 0/5] Add support for Silicon Mitus SM5703 MFD

This series adds support for Silicon Mitus SM5703 MFD and the
appropriate device-tree bindings. This only adds support for the
regulator module, leaving room for other modules implemented in
future (code for other modules is really not ready for submission
right now). Silicon Mitus SM5703 is used on various mobile phones,
mostly Samsung Galaxy (J5 (2015, 2016), On7, J7 (2015, 2016) ...).

v2:
- mfd bindings: add "SM5703" to the title
- mfd bindings: indent the example
- regulators/Makefile: sort alphabetically
v3:
- mfd bindings: fix an error in example: there should be no
  newline between #size-cells and #address-cells and the node
v4:
mfd bindings:
- drop the -mfd in the compatible
- change reference path to the regulator yaml to an absolute one
- use -gpios for the reset GPIO
- make reset-gpios a required property
- correct the example node name
- correct the example compatible
regulator bindings:
- add unevaluatedProperties: false to all four types of regulators
v5:
mfd driver:
- depend on OF for the SM5703 MFD (Kconfig)
- correct the compatible in the MFD driver
- remove the compatible of -regulators in the struct mfd_cell*
mfd bindings:
- adjust the example for regulators {} node
- include GPIO header in the example
- indent the example properly
- adjust the example for the voltage regulators being fixed
regulator bindings:
- remove the compatible
- refer to regulators.yaml
regulator driver:
- add a separate ops for fixed voltage regulators (to avoid kernel WARN)
- set the config.dev to dev->parent to probe from parent OF node
- (Kconfig) SM5703_MFD -> MFD_SM5703 fix typo

- Add a patch to avoid driver name conflicts in SM5502 extcon driver
