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. Patch 1 and 2 are hi6421-pmic cleaning up. Patch 3 and 4 extends hi6421-pmic-core.c to support Hi6421v530 revision. Patch 5 add hi6421v530-regulator.c driver for LDO regulators. Patch 6 fixes an issue for hi6421 regulator, which is not related to v530 but it's found in this review. Patch 7 is dts change, it depends on and can be applied to hi3660/hikey960 patchset [1]. Patch 8 enables the relevant config items. [1], http://www.spinics.net/lists/devicetree/msg178303.html Major changes in v6: - Patch 5, solve review comments from Mark Brown, add hi6421v530 regulator driver to module device table. - Add Acked-by from Arnd Bergmann Major changes in v5: - Patch 3, solve review comments from Lee Johes Major changes in v4: - put hi6421-pmic cleanup in separate patches. - solve review comments from Lee Johes. - regulator-name should not have '/' character. Otherwise it "Failed to create debugfs directory" Major changes in v3: - in hi6421-pmic-core.c * use shorter license script. * arrange #include in alphabetical order. * using recommended error log messages from Lee Jones. - in hi6421v530-regulator.c * remove unused #include files * arrange remaining ones in alphabetical order. Major changes in v2: - instead of writing a new driver, extend hi6421-pmic-core.c to support its v530 revision - update hi6421v530-regulator.c to use modern regulator driver design logics.
