[RFC v3 0/5] MT2701 DRM support

[YT Shen <yt.shen@mediatek.com>]

This is MT2701 DRM support RFC v3, based on 4.7-rc1.
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 v2:
- Rename mtk_ddp_mux_sel to mtk_ddp_sout_sel
- Update mt2701_mtk_ddp_ext components
- Changed to prefix naming
- Reorder the patch series
- Use of_device_get_match_data() to get driver private data
- Use iopoll macros to implement mtk_disp_mutex_acquire()
- Removed empty device tree nodes

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 the following patch:
https://patchwork.kernel.org/patch/8832441/ ("dt-bindings: ARM: Mediatek: Document bindings for MT2701"),
https://patchwork.kernel.org/patch/9140487/ ("dt-bindings: pwm: Add MediaTek display PWM bindings"),
https://patchwork.kernel.org/patch/9137919/ ("dt-bindings: mediatek: add descriptions for mediatek mt2701 iommu and smi"),
https://patchwork.kernel.org/patch/9137923/ ("iommu/mediatek: move the common struct into header file"),
https://patchwork.kernel.org/patch/9137921/ ("memory/mediatek: add support for mt2701"),
https://patchwork.kernel.org/patch/9137927/ ("iommu/mediatek: add support for mtk iommu generation one HW"),
https://patchwork.kernel.org/patch/9137931/ ("ARM: dts: mt2701: add iommu/smi dtsi node for mt2701"),

Thanks,
