This commit adds dtsi file for Sandbox PMIC. It fully describes the PMIC by: - i2c emul node - with a default settings of 16 registers - 2x buck regulator nodes - 2x ldo regulator nodes The default register settings are set with preprocessor macros: - VAL2REG(min[uV/uA], step[uV/uA], val[uV/uA]) - VAL2OMREG(mode id) Both defined in file: - include/dt-bindings/pmic/sandbox_pmic.h The Voltage ranges of each regulator can be found in: - include/power/sandbox_pmic.h The new file is included into: - sandbox.dts - test.dts Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org> Tested on sandbox: Tested-by: Simon Glass <sjg@chromium.org>
