[PATCH 3/3] drm/msm/dpu: drop dpu_encoder_phys_ops.atomic_mode_set

Dmitry Baryshkov dmitry.baryshkov at linaro.org
Sun Jun 4 14:45:14 UTC 2023


The atomic_mode_set() callback only sets the phys_enc's IRQ data. As the
INTF and WB are statically allocated to each encoder/phys_enc, drop the
atomic_mode_set callback and set the IRQs during encoder init.

For the CMD panel usecase some of IRQ indexes depend on the selected
resources. Move setting them to the irq_enable() callback.
