Subject: Applied "regulator: bd70528: Remove .set_ramp_delay for bd70528_ldo_ops" to the regulator tree

The patch

   regulator: bd70528: Remove .set_ramp_delay for bd70528_ldo_ops

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.5

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: bd70528: Remove .set_ramp_delay for
 bd70528_ldo_ops

The .set_ramp_delay should be for bd70528_buck_ops only.
Setting .set_ramp_delay for for bd70528_ldo_ops causes problem because
BD70528_MASK_BUCK_RAMP (0x10) overlaps with BD70528_MASK_LDO_VOLT (0x1f).
So setting ramp_delay for LDOs may change the voltage output, fix it.
