Core Voltages Clarification

[sudarkb]

Why does the Core voltage ( SOC and ARM voltage domain) are being changed in most revision of IMX6 application document. The latest revision of the document specifies the values as below for LDO enabled mode.

static struct cpu_op mx6dl_cpu_op_1G[] = {
{
.pll_rate = 996000000,
.cpu_rate = 996000000,
.cpu_podf = 0,
.pu_voltage = 1275000,
.soc_voltage = 1275000,
.cpu_voltage = 1350000,},
{
.pll_rate = 792000000,
.cpu_rate = 792000000,
.cpu_podf = 0,
.pu_voltage = 1275000,
.soc_voltage = 1275000,
.cpu_voltage = 1275000,},
{
.pll_rate = 396000000,
.cpu_rate = 396000000,
.cpu_podf = 0,
.pu_voltage = 1275000,
.soc_voltage = 1275000,
.cpu_voltage = 1250000,},
};

Is this settings safe to apply to older versions of IMX6 Solo processor like processors manufactured in 2016.

Yes, it's safe to apply the new values to earlier batches of the processors.

Have a great day,
