sysfs_emit() is preferred over sprintf() when formatting the value to be returned to user space in show() functions, because it knows about sysfs buffer specifics and has sanity checks. Signed-off-by:

Currently we are using BIT(), but GENMASK(). Make use of the latter one as well (far less error-prone, far more concise). Signed-off-by:

The driver depends on ACPI (via MFD_INTEL_PMC_BXT), ACPI_PTR() resolution is always the same. Otherwise a compiler may produce a warning. That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or none should be used in a driver. Signed-off-by:

Letting the compiler remove these functions when the kernel is built without CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based kernel configuration guards. Signed-off-by:

kstrtox() along with regmap API can return different error codes based on circumstances. Don't shadow them when returning to the caller. While at it, remove rather confusing message from addr_store(). Signed-off-by:

Add support for the MT6331 PMIC with MT6332 Companion PMIC, found in MT6795 Helio X10 smartphone platforms. This combo has support for multiple devices but, for a start, only the following have been implemented: - Regulators (two instances, one in MT6331, one in MT6332) - RTC (MT6331) - Keys (MT6331) - Interrupts (MT6331 also dispatches MT6332's interrupts) There's more to be implemented, especially for MT6332, which will come at a later stage.

The MT6331 PMIC provides many sub modules: regulators, audio codec, LED controller, keys, RTC and some GPIOs. It is always paired with a MT6332 Companion PMIC, which provides thermistors, WLEDs (display LED backlight), secondary AP cluster regulators, modem clocks, battery charger and fuel gauge. Add the necessary compatibles to start implementing the basics. Signed-off-by:

Maintaining a local driver data structure that is never shared outside of the core device is an unnecessary complexity. Half of the attributes were not used outside of a single function, one of which was not used at all. The remaining 2 are generic and can be passed around as required. Signed-off-by: -

There is no in-tree machine that provides a struct twl4030_platform_data since commit e92fc4f0 ("ARM: OMAP2+: Drop legacy board file for LDP"). So assume dev_get_platdata() returns NULL in twl_probe() and simplify accordingly. Signed-off-by:

Commit b38213c6 ("dt-bindings: mfd: maxim,max77693: Convert to dtschema") converts max77693.txt to maxim,max77693.yaml and adjusts the file entry in MAINTAINERS accordingly. Unfortunately, the merge commit afb67df3 ("Merge branches [...] into ibs-for-mfd-merged") resolves some conflict in MAINTAINERS in such a way that the file entry for the converted text file max77693.txt, removed in the commit above, is added back into MAINTAINERS. Remove the file entry to this converted text file in MAXIM PMIC AND MUIC DRIVERS FOR EXYNOS BASED BOARDS. Signed-off-by:

None of the in-tree instantiations of struct t7l66xb_platform_data provides a disable callback. So better don't dereference this function pointer unconditionally. As there is no user, drop it completely instead of calling it conditional. This is a preparation for making platform remove callbacks return void.
