2022-07-19mfd: mt6397: Add basic support for MT6331+MT6332 PMICAngeloGioacchino Del Regno1-0/+2
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.

2022-03-07mfd: Add support for the MediaTek MT6366 PMICJohnson Wang1-0/+1
This adds support for the MediaTek MT6366 PMIC. This is a multifunction device with the following sub modules: - Regulator - RTC - Codec - Interrupt It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap. MT6366 MFD is a child device of the pwrap.

2020-05-21mfd: mt6397: Modify suspend/resume behaviorHsin-Hsiung Wang1-0/+2
Some pmics don't need backup interrupt settings, so we change to use pm notifier for the pmics which are necessary to store settings. Signed-off-by: Hsin-Hsiung Wang <hsin-hsiung.wang@mediatek.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2019-08-12mfd: mt6397: Extract IRQ related code from core driverHsin-Hsiung Wang1-0/+9
In order to support different types of irq design, we decide to add separate irq drivers for different design and keep mt6397 mfd core simple and reusable to all generations of PMICs so far.
