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"),
