Subject: [PATCH v5] drm/rockchip: Remove dependency on DRM simple helpers
Date: Sat, 04 Jul 2026 11:12:02 +0200	[thread overview]
Message-ID: <20260704-rockchip-drm-simple-v5-1-a333f527a4f9@gmail.com> (raw)

Simple KMS helper are deprecated since they only add an intermediate
layer between drivers and the atomic modesetting.
This patch removes the drm_simple_encoder_init() helper usage in the
rockchip drivers by open coding it and using the encoder atomic helpers
directly. This is a step to eventually get rid of this simple KMS helper,
once all drivers that use it have been converted.

Reviewed-by: Javier Martinez Canillas <javierm@redhat.com>

---
v5:
 - fixed formatting and some indentation

v4:
 - improved commit message based on Javier Canillas feedback

v3:
 - rebase on drm-tip tree
