From 2f4ffd14b6c0556ae0b5e5ba5691ba8fc6d1fcad Mon Sep 17 00:00:00 2001 From: Antti Laakso Date: Thu, 27 Aug 2026 15:33:36 +0300 Subject: [PATCH] media: ipu6: Enable support for IPU 7 and IPU 7.5 Enable support for Intel IPU 7 and IPU 7.5, found in Lunar lake and Panther lake, respectively, in the ipu6 driver. Disabling the CONFIG_VIDEO_INTEL_IPU6_IPU7 Kconfig option can be used to still default the support of IPU7 and 7.5 to the ipu7 driver, while default is enabled. The driver binding can still be configured at runtime by using force_probe and force_no_ipu7_probe options in ipu6 and ipu7 drivers, respectively.
