[PATCH 1/3] regulator: arizona: Update device tree binding to support Madera CODECs

[Charles Keepax]

The Arizona regulator drivers are now also used by the Cirrus Logic
Madera audio CODECs, update the binding document to link to the primary
binding document for these as well as the existing Arizona document.

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

Applied "regulator: arizona: Update device tree binding to support Madera CODECs" to the regulator tree

[Mark Brown]

The patch

   regulator: arizona: Update device tree binding to support Madera CODECs

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: arizona: Update device tree binding to support
 Madera CODECs

The Arizona regulator drivers are now also used by the Cirrus Logic
Madera audio CODECs, update the binding document to link to the primary
binding document for these as well as the existing Arizona document.
