The regulators for DA9061 differ from those of DA9062. A new DA9061 enumeration list for the LDOs and Bucks supported by this device is added. Regulator information added: the old regulator information for DA9062 is renamed from local_regulator_info[] to local_da9062_regulator_info[] and a new array is added to support local_da9061_regulator_info[]. The probe() function switches on the da9062_compatible_types enumeration and configures the correct da9062_regulator_info array and number of regulator entries. Kconfig is updated to reflect support for DA9061 and DA9062 regulators. Acked-by: Mark Brown Signed-off-by: Steve Twiss --- Hi, This patch was Acked by Mark Brown, a long time ago, way back in Oct 2016 (https://patchwork.kernel.org/patch/9397787/). I have kept Mark Brown's Ack attached because there have been no real code changes since then, but I have recently updated the copyright header slightly, rebased the code (no changes necessary) and compile tested it against x86_64. The MFD files which this patch depended on were accepted into linux-next by Lee Jones last week. If there is anything in the way of this patch acceptance, could you please let me know? Regards, Steve This patch applies against linux-next and v4.12-rc2 v6 -> v7 - NO CODE CHANGE - Compile tested ARCH=x86_64 v5 -> v6 - Rebased from v4.9 to v4.11-rc3 - Modify Copyright to match Dialog latest legal statement v4 -> v5 - Rebased from v4.8 to v4.9 - NO CODE CHANGE v3 -> v4 - NO CODE CHANGE - Patch renamed from [PATCH V3 6/9] to [PATCH V4 5/8] v2 -> v3 - NO CODE CHANGE - Patch renamed from [PATCH V2 06/10] to [PATCH V3 6/9] - Added Ack from Mark Brown v1 -> v2 - Patch renamed from [PATCH V1 02/10] to [PATCH V2 06/10] -- these changes were made to fix checkpatch warnings caused by the patch set dependency order - Updated header to use DA9061 and DA9062 Hi, I have updated copyright header slightly to match Dialog's legal expectation, but there are no code changes for this version PATCH V7. As previously: These changes depend on a header file provided as part of an earlier patch [V7,4/7] mfd: da9061: MFD core support from this set. The regulator probe() switches on the chip_type which uses enum da9062_compatible_types in core.h from this patch.
