Add DT bindings for the ROHM BD9571MWV-M PMIC. This PMIC has the following features: - multiple voltage monitors for 1V8, 2V5, 3V3 voltage rail - one voltage regulator for DVFS - two GPIOs Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: devicetree@vger.kernel.org Cc: Rob Herring <robh@kernel.org> Cc: Geert Uytterhoeven <geert+renesas@glider.be> Cc: linux-renesas-soc@vger.kernel.org --- V2: - Drop the compatible = "regulator-fixed" from the binding example, it should not be there. - List the VD09 regulator --- .../devicetree/bindings/mfd/bd9571mwv.txt | 49 ++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/bd9571mwv.txt
