2019-02-21regulator: fan53555: Add support for FAN53526Bjorn Andersson
The FAN53526 differs from the FAN53555 only in that the mode bit in VSEL0/VSEL1 is moved to the CONTROL register, the voltage selector mask is extended by 1 bit and the step is different. So extend the existing fan53555 driver to support FAN53526 as well. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2019-02-14devicetree: bindings: bd718x7: document HW state related ROHM specific ↵Matti Vaittinen
properties Add ROHM BD71837 / BD71847 specific device tree bindings for controlling the PMIC shutdown/reset states and voltages for different HW states. The PMIC was designed to be used with NXP i.MX8 SoC and it supports SNVS low power state which seems to be typical for NXP i.MX SoCs. However, when SNVS is used we must not allow SW to control enabling/disabling those regulators which are crucial for system to boot as there is a HW limitation which causes SW controlled regulators to be kept shut down after SNVS reset. Allow setting the SNVS to be used as reset target state and allow marking those regulators which are critical for boot.

2019-02-08dt-bindings: regulator: update fixed-regulator exampleJohan Hovold
Fixed regulators do not have associated bus addresses and are typically placed directly under the root node where their names must still be unique despite not having a unit address. Fix the malformed example node which had a unit address but no "reg" property by dropping the unit address. Also, try to make the example more useful by using the recommended generic node name "regulator", but with a suffix reflecting the regulator name in order to make it unique.

2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.
