[ Upstream commit401aec35ac] We have experienced seen multiple I2C errors while doing stress test on the module: dw9714 i2c-PRP0001:01: dw9714_vcm_resume I2C failure: -5 dw9714 i2c-PRP0001:01: I2C write fail Inspecting the powerup sequence we found that it does not match the documentation at: https://blog.arducam.com/downloads/DW9714A-DONGWOON(Autofocus_motor_manual).pdf """ (2) DW9714A requires waiting time of 12ms after power on. During this waiting time, the offset calibration of internal amplifier is operating for minimization of output offset current . """ This patch increases the powerup delay to follow the documentation.
