This is MT2701 DRM support RFC, based on MT8173 DRM patch v16. Most codes are the same, except some register changed.
For example: - DISP_OVL address offset changed, color format definition changed. - DISP_RDMA fifo size changed. - DISP_COLOR offset changed.
We add a new component DISP_BLS, and the connection settings are updated. And we have shadow register support in MT2701.
Changes since v1: - Removed BLS bindings and codes, which belong to pwm driver - Moved mtk_disp_mutex_acquire() just before mtk_crtc_ddp_config() - Split patch into smaller parts - Added const keyword to constant structure - Removed codes for special memory align
The RFC depends on MT2701 iommu/smi driver. https://patchwork.kernel.org/patch/9043411/ ("dt-bindings: mediatek: add descriptions for mediatek mt2701 iommu and smi"), https://patchwork.kernel.org/patch/9043391/ ("iommu/mediatek: move the common struct into header file"), https://patchwork.kernel.org/patch/9043421/ ("memory/mediatek: add support for mt2701"), https://patchwork.kernel.org/patch/9043451/ ("iommu/mediatek: add support for mtk iommu generation one HW"), https://patchwork.kernel.org/patch/9043471/ ("ARM: dts: mt2701: add iommu/smi dtsi node for mt2701"),
Thanks, yt.shen
