Subject[RFCv2,1/2] v4l2-controls.h: add addtional Flash fault bits
Date
Add additional FLASH Fault bits to dectect faults from chip.
Some Flash drivers support UVLO, IVFM, NTC Trip faults.
UVLO : Under Voltage Lock Out Threshold crossed
IVFM : IVFM block reported and/or adjusted LED current Input Voltage Flash Monitor trip threshold
NTC : NTC Threshold crossed. Many Flash drivers have a pin and the fault bit to
serves as a threshold detector for negative temperature coefficient (NTC) thermistors.
