Doesn't the PMC also receive a "clk32k_in" from the PMIC, or is that routed into the CAR, and then into the PMC? Either way, the PMC module receives that clock somehow. Since there are multiple clocks, that also means that a clock-names property is required. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
