Hi,

I'm working on low power management in imx6ull evk. I found a dedicated pin CCM_PMIC_STBY_REQ and GPIO_DVFS.

And I'm getting following results in power state = standby,

PMIC_STBY_REQ = 0, GPIO_DVFS = 0, output is 1.4V (1.375V + 25mV)
PMIC_STBY_REQ = 0, GPIO_DVFS = 1, output is 1.3V (1.275V + 25mV)

 

  1. But I have a doubt in below condition

      PMIC_STBY_REQ = 1, GPIO_DVFS = 0, output is 0.925V (0.9V + 25mV)

      How to get the above condition, I'm unable to find any configuration for CCM_PMIC_STBY_REQ in dts or pm_imx6.c.

   2. Whether this condition is achieved in any other power state.

 

awaiting your response.
