Subject: Applied "regulator: da9063: fix DT probing with constraints" to the regulator tree

The patch

   regulator: da9063: fix DT probing with constraints

has been applied to the regulator tree at

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

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: da9063: fix DT probing with constraints

Commit 1c892e38ce59 ("regulator: da9063: Handle less LDOs on DA9063L")
reordered the da9063_regulator_info[] array, but not the DA9063_ID_*
regulator ids and not the da9063_matches[] array, because ids are used
as indices in the array initializer. This mismatch between regulator id
and da9063_regulator_info[] array index causes the driver probe to fail
because constraints from DT are not applied to the correct regulator:

  da9063 0-0058: Device detected (chip-ID: 0x61, var-ID: 0x50)
  DA9063_BMEM: Bringing 900000uV into 3300000-3300000uV
  DA9063_LDO9: Bringing 3300000uV into 2500000-2500000uV
  DA9063_LDO1: Bringing 900000uV into 3300000-3300000uV
  DA9063_LDO1: failed to apply 3300000-3300000uV constraint(-22)

This patch reorders the DA9063_ID_* as apparently intended, and with
them the entries in the da90630_matches[] array.
