ENGR00139213: Add read and change voltage support for mx6
dd read and change voltage support for mx6. For help, pls type "help regul" Detail command info: regul list - List all regulators' name regul show all - Display all regulators' voltage regul show core - Show core voltage in mV regul show periph - Show peripheral voltage in mV regul show <regulator name> - Show regulator's voltage in mV regul set core <voltage value> - Set core voltage in mV regul set periph <voltage value> - Set periph voltage in mV regul set <regulator name> <voltage value> - Set regulator's voltage in mV Example: MX6Q ARM2 U-Boot > regul list Name Voltage vddpu vddcore vddsoc vdd2p5 vdd1p1 vdd3p0 MX6Q ARM2 U-Boot > regul show all Name Voltage vddpu 1100000 vddcore 1100000 vddsoc 1200000 vdd2p5 2400000 vdd1p1 1100000 vdd3p0 3000000 MX6Q ARM2 U-Boot > regul show periph Name Voltage periph: 1100000 MX6Q ARM2 U-Boot > regul show core Name Voltage core: 1100000 MX6Q ARM2 U-Boot > regul set core 1100000 Set voltage succeed!
