+       Enable the driver for Sandbox PMIC emulation. The emulated PMIC device
+       depends on two drivers:
+       - sandbox PMIC I/O driver - implements dm pmic operations
+       - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
+
+       A detailed information can be found in header: '<power/sandbox_pmic.h>'
+
+       The Sandbox PMIC info:
+       * I/O interface:
+         - I2C chip address:       0x40
+         - first register address: 0x0
+         - register count:         0x10
+       * Adjustable outputs:
+         - 2x LDO
+         - 2x BUCK
+         - Each, with a different operating conditions (header).
+       * Reset values:
+         - set by i2c emul driver's probe() (defaults in header)
