CVE-2024-53682: regulator: axp20x: AXP717: set ramp_delay
Description
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 AXP_DESC_RANGES_DELAY macro and update AXP_DESC_RANGES macro to
expand to AXP_DESC_RANGES_DELAY with ramp_delay = 0
For DCDC4, steps is 100mv
Add a AXP_DESC_DELAY macro and update AXP_DESC macro to
expand to AXP_DESC_DELAY with ramp_delay = 0
This patch fix crashes when using CPU DVFS.
