Subject: [PATCH v3 09/10] media: i2c: imx290: Move the settle time delay out of loop
Date: Sun, 24 May 2020 22:25:04 +0300 [thread overview]
Message-ID: <20200524192505.20682-10-andrey.konovalov@linaro.org> (raw)
In-Reply-To: <20200524192505.20682-1-andrey.konovalov@linaro.org>
From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
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().
