[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

Applied it because this patch depends on already merged patch
on extcon-next branch.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
