This series adds support for the regulators found in MT6331 and MT6332 main/companion PMICs. Adding support to each driver in each subsystem is done in different patch series as to avoid spamming uninteresting patches to maintainers. Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone. 2022-09-13T14:04:58+00:00 AngeloGioacchino Del Regno angelogioacchino.delregno@collabora.com 2022-09-13T12:34:56+00:00 urn:sha1:1cc5a52e873a4f9725eafe5aa9cd213b7b58e29e Add a driver for the regulators found in the MT6332 PMICs, including six buck and four LDO regulators.
