This is MT2701 DRM support PATCH v9, based on 4.9-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.
We remove dts patch from the patch series, which depends on MT2701 CCF and scpsys.
Changes since v8: - enable 3 DSI interrupts only - move mtk_dsi_wait_for_irq_done() to the patch of irq control - use the name BLS in DRM driver part - move BLS declaration to a separate patch - update mtk_dsi_switch_to_cmd_mode() - update mtk_output_dsi_enable() and mtk_output_dsi_disable()
Changes since v7: - Remove redundant codes - Move the definition of DDP_COMPONENT_BLS to patch of "drm/mediatek: update display module connections" - Move _dsi_irq_wait_queue into platform driver data - Move mtk_dsi_irq_data_clear() to patch of "drm/mediatek: add dsi interrupt control" - Add more descriptions in the commit messages
Changes since v6: - Change data type of irq_data to u32 - Rewrite mtk_dsi_host_transfer() for simplify - Move some MIPI_TX config to patch of "drm/mediatek: add *driver_data for different hardware settings". - Remove device tree from this patch series
Changes since v5: - Remove DPI device tree and compatible string - Use one wait queue to handle interrupt status - Update the interrupt check flow and DSI_INT_ALL_BITS - Use same function for host read/write command - various fixes
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
