[PATCH v7 0/2] media: i2c: imx412: power on timing adjust

[Wenmeng Liu <wenmeng.liu@oss.qualcomm.com>]

This series of patches mainly addresses two issues:
1. Fix potential timing issues that may occur during the first and second power on.
If the reset GPIO happens to default to the deasserted state at the very
first power-up, the previous sequence could let the sensor run before
supplies/clock are fully stable, while subsequent power cycles would
differ because the driver explicitly toggles reset. This results in
inconsistent power on sequences between the first and later power on.

2. The Arducam IMX577 sensor requires a longer reset time.
