[PATCH v7 2/8] media: qcom: iris: use common set_preset_registers function
From: Dmitry Baryshkov
Date: Mon Mar 16 2026 - 14:55:25 EST
The set_preset_registers is (currently) common to all supported devices.
Extract it to a iris_vpu_common.c and call it directly from
iris_vpu_power_on(). Later, if any of the devices requires special
handling, it can be sorted out separately.
