[PATCH v4 09/10] media: i2c: imx290: Move the settle time delay out of loop
From: Andrey Konovalov
Date: Sun Jun 07 2020 - 12:31:22 EST
From: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>
The 10ms settle time is needed only at the end of all consecutive
register writes. So move the delay to outside of the for loop of
imx290_set_register_array().
