From e6d6d3620e20f6eddf92f71e30a7e0c47d403489 Mon Sep 17 00:00:00 2001 From: V Sowmya Date: Sat, 24 Sep 2022 21:47:55 +0530 Subject: drivers/intel/mipi_camera: Remove IPU ES support entry for ADL-N The current IPU ES entry value is always set to true for ADL-N and kernel picks the ES version of the main IPU FW even for the production bootloader but loading is not successful due to the authentication failure. Alderlake-N silicon has the same CPU id for all the SKU's and also the production binaries are backward compatible with ES parts. This change removes the IPU ES support ACPI entry since the kernel needs to load the production IPU main firmware on both the ES/QS parts. BUG=b:248249032 TEST=Verify the Camera functionality by enabling the IPU secure mode on ADL-N variants with both ES/QS silicon.
