2019-07-02mfd: rk808: Prepare rk805 for poweroffStefan Mavrodiev1-15/+35
RK805 has SLEEP signal, which can put the device into SLEEP or OFF mode. The default is SLEEP mode. However, when the kernel performs power-off (actually the ATF) the device will not go fully off and this will result in higher power consumption and inability to wake the device with RTC alarm. The solution is to enable pm_power_off_prepare function, which will configure SLEEP pin for OFF function.

2019-07-02mfd: rk808: Check pm_power_off pointerStefan Mavrodiev1-6/+11
The function pointer pm_power_off may point to function from other module (PSCI for example). If rk808 is removed, pm_power_off is overwritten to NULL and the system cannot be powered off. This patch checks if pm_power_off points to a module function. Signed-off-by: Stefan Mavrodiev <stefan@olimex.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2015-03-12mfd: rk808: Disable the under voltage detectChris Zhong1-0/+1
Rk808 has a under voltage detect function, when the voltage of buck is under 85% the target voltage, the buck output will reset. But if the power load is too heavy, this function maybe err, when current over 4.2A, although the voltage is normal, but RK808 mistakenly think it is under 85%, and reset the buck. So let's disable this function. Signed-off-by: Chris Zhong <zyw@rock-chips.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
