Subject: Applied "dt-bindings: regulator: add support for the stm32-booster" to the regulator tree

The patch

   dt-bindings: regulator: add support for the stm32-booster

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] dt-bindings: regulator: add support for the stm32-booster

Document the 3.3V booster regulator embedded in stm32h7 and stm32mp1
devices, that can be used to supply ADC analog input switches.
It's controlled by using system configuration registers (SYSCFG).
Introduce two compatibles as the booster regulator is controlled by:
- a unique register/bit in STM32H7
- a set/clear register pair in STM32MP1

+STM32 BOOSTER - Booster for ADC analog input switches
+
+Some STM32 devices embed a 3.3V booster supplied by Vdda, that can be used
+to supply ADC analog input switches.
+
+Required properties:
+- compatible: Should be one of:
+  "st,stm32h7-booster"
+  "st,stm32mp1-booster"
+- st,syscfg: Phandle to system configuration controller.
+- vdda-supply: Phandle to the vdda input analog voltage.
+
+Example:
+	booster: regulator-booster {
+		compatible = "st,stm32mp1-booster";
+		st,syscfg = <&syscfg>;
+		vdda-supply = <&vdda>;
+	};
