In the Linux kernel, the following vulnerability has been resolved:
regulator: axp20x: AXP717: set ramp_delay
AXP717 datasheet says that regulator ramp delay is 15.625 us/step, which is 10mV in our case.
Add a AXPDESCRANGESDELAY macro and update AXPDESCRANGES macro to expand to AXPDESCRANGESDELAY with ramp_delay = 0
For DCDC4, steps is 100mv
Add a AXPDESCDELAY macro and update AXPDESC macro to expand to AXPDESCDELAY with rampdelay = 0
This patch fix crashes when using CPU DVFS.
