Subject: [RFC v2 0/5] MT2701 DRM support

From: YT Shen <yt.shen@...iatek.com>

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
