This is MT2701 DRM support PATCH v5, based on 4.7-rc1. We add DSI interrupt control, transfer function for MIPI DSI panel support. 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. - MIPI_TX setting changed.
We add a new component DDP_COMPONENT_BLS, and the connections are updated. OVL -> RDMA -> COLOR -> BLS -> DSI RDMA -> DPI And we have shadow register support in MT2701.
Changes since v4: - Add messages when timeout in mtk_disp_mutex_acquire() - Add descriptions for DISP_REG_MUTEX registers - Move connection settings for display modules to a separate patch - Remove 'mt2701-disp-wdma' because it is unused - Move cleaning up and renaming to a separate patch - Use wait_event_interruptible_timeout() to replace polling - Remove irq_num from mtk_dsi structure - Remove redundant and debug codes
Changes since v3: - Add DSI support for MIPI DSI panels - Update BLS binding to PWM nodes - Remove ufoe device nodes - Remove redundant parentheses - Remove global variable initialization
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
