From 20af6be6bee4c3af80aac9b44b3d32d89824dde7 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Tue, 14 Feb 2023 17:35:39 +0000 Subject: [PATCH] media: nxp: imx8-isi: Remove 300ms sleep after enabling channel The current implementation of the mxc_isi_channel_enable() function has a hard 300ms sleep. This was copied from the NXP BSP, which has since dropped the sleep in a commit that implied the delay was meant to wait for the sensor to be "stable". As the sensor is started after the ISI, the delay won't affect sensor operation. Drop it.
