Subject: Applied "regulator: axp20x: fix DCDCA and DCDCD for AXP806" to the regulator tree

The patch

   regulator: axp20x: fix DCDCA and DCDCD for AXP806

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.3

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] regulator: axp20x: fix DCDCA and DCDCD for AXP806

Refactoring of the driver introduced bugs in AXP806's DCDCA and DCDCD
regulator definitions.

In DCDCA case, AXP806_DCDCA_1120mV_STEPS was obtained by subtracting
0x47 and 0x33. This should be 0x14 (hex) and not 14 (dec).

In DCDCD case, axp806_dcdcd_ranges[] contains two ranges with same
start and end macros, which is clearly wrong. Second range starts at
1.6V so it should use AXP806_DCDCD_1600mV_[START|END] macros. They are
already defined but unused.
