[PATCH v2] drm/tilcdc: Precalculate total frametime in tilcdc_crtc_set_mode()

We need the total frame refresh time to check if we are too close to vertical sync when updating the two framebuffer DMA registers and risk a collision. This new method is more accurate that the previous that based on mode's vrefresh value, which itself is inaccurate or may not even be

[PATCH v2] drm/vc4: Fix sleeps during the IRQ handler for DSI transactions.

VC4's DSI1 has a bug where the AXI connection is broken for 32-bit writes from the CPU, so we use the DMA engine to DMA 32-bit values into registers instead. That sleeps, so we can't do it from the top half. As a solution, use an interrupt thread so that all our writes happen when sleeping is is

[PATCH 6/7] drm/sun4i: hdmi: Document PAD_CTRL1 output invert bits

While debugging inverted color from the HDMI output on the A10, I found that the lowest 3 bits were set. These were cleared on A20 boards that had normal display output. By manually toggling these bits the mapping of the color components to these bits was found. While these are not used anywhere,

Initially we configured the PAD_CTRL1 register at probe/bind time. However it seems the HDMI controller will modify some of the bits in this register by itself. On the A10 it is particularly annoying as it toggles the output invert bits, which inverts the colors on the display output. The U-boot

[PATCH 4/7] drm/sun4i: backend: Add comment explaining why registers are cleared

Many of the backend's layer configuration registers have undefined default values. This poses a risk as we use regmap_update_bits in some places, and don't overwrite the whole register. At probe/bind time we explicitly clear all the control registers by writing 0 to them. This patch adds a more

[PATCH 43/48] drm: omapdrm: dss: Pass omap_drm_private pointer to dss_mgr_ops

The dss_mgr_ops operations implemented by the omapdrm side have to look up the omap_crtc objects from global variables as they are only passed a channel number. In order to remove global variables pass the omap_drm_private pointer to the dss_mgr_ops. This requires storing a pointer to the

[PATCH 40/48] drm: omapdrm: dsi: Don't pass channel to dispc init/uninit functions

The dsi_display_init_dispc() and dsi_display_uninit_dispc() functions take a channel argument that is reduntant as it is always identical to the dsi->output.dispc_channel. Remove the argument and use the field directly in the functions to avoid misuse. Signed-off-by: Laurent Pinchart

[PATCH 45/48] drm: omapdrm: dispc: Pass DISPC pointer to remaining dispc API functions

This removes the need to access the global DISPC private data in those functions (both for the current accesses and the future ones that will be introduced when allocating the DISPC private data dynamically). Signed-off-by: Laurent Pinchart ---

[PATCH 47/48] drm: omapdrm: dss: Store the debugfs root directory in struct dss_device

As part of an effort to remove the usage of global variables in the driver, store the debugfs root directory in the dss_device structure instead of a global variable. Signed-off-by: Laurent Pinchart --- drivers/gpu/drm/omapdrm/dss/dispc.c | 2 +-

[PATCH 39/48] drm: omapdrm: dsi: Store the struct device pointer in struct dsi_data

The dsi_data structure stores a pointer to a struct platform_device. The driver only uses the dev member of the platform device structure. Store the struct device pointer instead and use it directly. Signed-off-by: Laurent Pinchart ---

[PATCH 38/48] drm: omapdrm: dsi: Use dev pointer directly in dsi_bind() function

The dsi_bind() function receives a pointer to a struct device that it casts to a struct platform_device, only to use the platform device's dev field through the code. Use the dev pointer directly. While at it rename the struct platform_device pointer dsidev to pdev to make it more explicit.

[PATCH 33/48] drm: omapdrm: venc: Allocate the venc private data structure dynamically

The venc private data structure is currently stored as a global variable. While no platform with multiple VENC encoders currently exists nor is planned, this doesn't comply with the kernel device model and should thus be fixed. Signed-off-by: Laurent Pinchart

[PATCH 00/48] omapdrm: Merge omapdrm and omapdss

Hello, This patch series merges the omapdrm and omapdss drivers into a single driver called omapdrm. The split in two drivers was historical, in order to support the FBDEV, V4L2 and DRM/KMS APIs. Now that the driver supports DRM/KMS only there's no need to keep two seperate drivers. The series
