From mboxrd@z Thu Jan 1 00:00:00 1970 From: guodong.xu@linaro.org (Guodong Xu) Date: Fri, 26 May 2017 14:35:12 +0800 Subject: [PATCH 0/6] MFD: add driver for HiSilicon Hi6421v530 PMIC Message-ID: <20170526063518.21246-1-guodong.xu@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patchset adds driver for HiSilicon Hi6421v530 PMIC. Mainline kernel already has driver support to a similar chip, Hi6421. Hi6421 and Hi6421v530 are both from the same vendor, HiSilicon, but they are at different revisions. They both use the same Memory-mapped I/O method to communicate with Main SoC. However, they differ quite a lot in their regulator designs. Eg. they have completely different LDO voltage points. In order to enable future extension of Hi6421v530 functionality, a new mfd driver and regulator driver are added in this patchset. Only header file hi6421-pmic.h is reused between them. Patch 2 is for just this purpose. Patch 3 and 4 adds mfd and regulator driver respectively. Patch 5 is dts change, it depends and can be applied on hi3660/hikey960 patchset [1]. Patch 6 enables the relevant config items.
