Some STM32 devices embed a voltage reference buffer which can be used as voltage reference for ADCs, DACs and also as voltage reference for external components through the dedicated VREF+ pin. This patchset adds vrefbuf regulator driver, device tree bindings and vrefbuf device tree node for STM32H7 SoC. --- Changes in v2: - Update regulator driver following Mark's remarks Fabrice Gasnier (3): dt-bindings: regulator: Add STM32 Voltage Reference Buffer regulator: Add support for stm32-vrefbuf ARM: dts: stm32: add vrefbuf to stm32h743 .../bindings/regulator/st,stm32-vrefbuf.txt | 20 ++ arch/arm/boot/dts/stm32h743.dtsi | 9 + drivers/regulator/Kconfig | 12 ++ drivers/regulator/Makefile | 1 + drivers/regulator/stm32-vrefbuf.c | 202 +++++++++++++++++++++ 5 files changed, 244 insertions(+) create mode 100644 Documentation/devicetree/bindings/regulator/st,stm32-vrefbuf.txt create mode 100644 drivers/regulator/stm32-vrefbuf.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
