This patch adds support for ON Semiconductor FAN53880 regulator.
The FAN53880 is an I2C porgrammable power management IC (PMIC)
that contains a BUCK (step-down converter), four LDOs (low dropouts)
and one BOOST (step-up converter). It is designed for mobile power
applications.

function" from Anand K Mistry <amistry@google.com>:
This patchset adds support for being able to change regulator modes for
the mt6397 regulator. This is needed to allow the voltage scaling
support in the MT8173 SoC to be used on the elm (Acer Chromebook R13)
and hana (several Lenovo Chromebooks) devices.
Without a of_map_mode implementation, the regulator-allowed-modes
devicetree field is skipped, and attempting to change the regulator mode
results in an error:
[ 1.439165] vpca15: mode operation not allowed
Changes in v2:
- Introduce constants in dt-bindings
- Improve conditional readability

<wcheng@codeaurora.org>:
Changes in v4:
- Modified qcom,pmic-typec binding to include the SS mux and the DRD remote
endpoint nodes underneath port@1, which is assigned to the SSUSB path
according to usb-connector
- Added usb-connector reference to the typec dt-binding
- Added tags to the usb type c and vbus nodes
- Removed "qcom" tags from type c and vbus nodes
- Modified Kconfig module name, and removed module alias from the typec driver
Changes in v3:
- Fix driver reference to match driver name in Kconfig for
qcom_usb_vbus-regulator.c
- Utilize regulator bitmap helpers for enable, disable and is enabled calls in
qcom_usb_vbus-regulator.c
- Use of_get_regulator_init_data() to initialize regulator init data, and to
set constraints in qcom_usb_vbus-regulator.c
- Remove the need for a local device structure in the vbus regulator driver
Changes in v2:
- Use devm_kzalloc() in qcom_pmic_typec_probe()
- Add checks to make sure return value of typec_find_port_power_role() is
valid
- Added a VBUS output regulator driver, which will be used by the PMIC USB
type c driver to enable/disable the source
- Added logic to control vbus source from the PMIC type c driver when
UFP/DFP is detected
- Added dt-binding for this new regulator driver
- Fixed Kconfig typec notation to match others
- Leave type C block disabled until enabled by a platform DTS
Add the required drivers for implementing type C orientation and role
detection using the Qualcomm PMIC. Currently, PMICs such as the PM8150B
have an integrated type C block, which can be utilized for this. This
series adds the dt-binding, PMIC type C driver, and DTS nodes.
The PMIC type C driver will register itself as a type C port w/ a
registered type C switch for orientation, and will fetch a USB role switch
handle for the role notifications. It will also have the ability to enable
the VBUS output to any connected devices based on if the device is behaving
as a UFP or DFP.

This driver enables outputs by setting bit EN_BUCKn in the BUCKn_CTRL1
register. However, if bit EN_PIN_CTRLn in the same register is set, the
output is actually enabled only if EN_BUCKn is set AND an enable pin is
active. Since the driver does not touch EN_PIN_CTRLn, the choice is left to
the hardware, which in turn gets this bit from OTP memory, and in absence
of OTP data it uses a default value that is documented in the datasheet for
LP8752x, but not for LP8756x.
Thus the driver doesn't really "know" whether it is actually enabling the
output or not.
In order to make sure activation is always driver-controlled, just clear
the EN_PIN_CTRLn bit. Now all activation solely depend on the EN_BUCKn bit.

Pi-Hsun Shih <pihsun@chromium.org>:
Add support for controlling voltage regulator that is connected and
controlled by ChromeOS EC. Kernel controls these regulators through
newly added EC host commands.
Changes from v5:
* Move new host command to a separate patch.
* Use devm_regulator_register.
* Address review comments.
Changes from v4:
* Change compatible name from regulator-cros-ec to cros-ec-regulator.
Changes from v3:
* Fix dt bindings file name.
* Remove check around CONFIG_OF in driver.
* Add new host commands to cros_ec_trace.
* Address review comments.
Changes from v2:
* Add 'depends on OF' to Kconfig.
* Add Kconfig description about compiling as module.
Changes from v1:
* Change compatible string to google,regulator-cros-ec.
* Use reg property in device tree.
* Change license for dt binding according to checkpatch.pl.
* Address comments on code styles.
