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)
- 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.
