From 07444c60ff31b594a09621d0753761f09d73bf07 Mon Sep 17 00:00:00 2001 From: Jai Luthra Date: Fri, 21 Feb 2025 16:22:14 +0530 Subject: [PATCH] media: i2c: imx219: Use subdev state to calculate binning and pixelrate The pixel rate and binning calculations need the format and resolution of the sensor, so pass the v4l2 subdev state directly instead of always operating on the active state.
