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. Signed-off-by: Johnson Wang <[email protected]> Signed-off-by: Lee Jones <[email protected]> Link: https://lore.kernel.org/r/[email protected]
