Subject: [PATCH v2 0/2] add the dvs support for rk808
Date: Thu, 11 Dec 2014 11:16:40 +0800 [thread overview]
Message-ID: <1418267802-13159-1-git-send-email-zyw@rock-chips.com> (raw)
rk808 has a dvs function, there are 3 pins for dvs, dvs1 & dvs2 & dvsok.
Normally, the voltage of DCDC1/DCDC2 are controlled by BUCKn_ON_VSEL, when
we pull dvs1/dvs2 pin to active, they would be controlled by BUCKn_DVS_VSEL.
And the dvsok pin is used to indicate whether regulating has been completed.
When dvs1/dvs2 pin change, dvsok would be pull down, and it would be pull up
once the regulating is complete.
Changes in v2:
- increase description about dvs pins
- modify the multiline commenting
Chris Zhong (2):
mfd: dt-bindings: add the description about dvs gpio for rk808
