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 regulator: rk808: add dvs support Documentation/devicetree/bindings/mfd/rk808.txt | 13 +- drivers/regulator/rk808-regulator.c | 192 ++++++++++++++++++++++-- 2 files changed, 192 insertions(+), 13 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
