gpu: ipu-v3: ipu-dc: Remove unused 'di' variable

2017-10-04T10:18:56Z

The 'di' variable is never used inside ipu_dc_enable_channel(), so just remove it. This fixes the following build warning with W=1: drivers/gpu/ipu-v3/ipu-dc.c: In function 'ipu_dc_enable_channel': drivers/gpu/ipu-v3/ipu-dc.c:252:6: warning: variable 'di' set but not used [-Wunused-but-set-variable] Signed-off-by: Fabio Estevam Signed-off-by: Philipp Zabel

gpu: ipu-v3: remove IRQ dance on DC channel disable

2017-03-15T14:28:27Z

This has never worked properly, as the IRQ got retriggered immediately on unmask. Remove the IRQ wait dance, as it is apparently safe to disable the DC channel at any point in time. Signed-off-by: Lucas Stach Signed-off-by: Philipp Zabel

gpu: ipu-v3: ipu-dc: don't bug out on invalid bus_format

2016-07-12T16:26:05Z

If imx-drm is combined with a bridge or panel that requests an unsupported format, warn and use a default mapping instead of hanging the machine. The worst that can happen here are wrong colors. Signed-off-by: Philipp Zabel

drm/imx: atomic phase 1: Use transitional atomic CRTC and plane helpers

2016-07-12T16:23:47Z

Use the drm_plane_helper_update/disable() and drm_helper_crtc_mode_set() transitional atomic helpers. The crtc->mode_set_nofb callback is added so that the primary plane is no longer tied to the CRTC. Check/update logics are separated to make sure crtc->mode_set_nofb and plane->atomic_update are always successful. Also, some necessary logics are tweaked for a smooth transition.

gpu: ipu-v3: ipu-dc: Simplify display controller microcode setup

2016-03-01T07:33:38Z

This cleans up the display controller microcode setup in ipu_dc_init_sync a little bit. The microcode template words for DI0 and DI1 are properly separated to avoid a clash when DI1 is active in interlaced mode at the same time as DI0 in non-interlaced mode. A comment is added to explain the meaning of the sync counter. Signed-off-by: Philipp Zabel

gpu: imx: fix support for interlaced modes

2015-10-06T18:58:30Z

The support for interlaced video modes seems to be broken; we don't use anything other than the vtotal/htotal from the timing information to define the various sync counters. Freescale patches for interlaced video support contain an alternative sync counter setup, which we include here. This setup produces the hsync and vsync via the normal counter 2 and 3, but moves the display enable signal from counter 5 to counter 6. Therefore, we need to change the display controller setup as well. The corresponding Freescale patches for this change are: iMX6-HDMI-support-interlaced-display-mode.patch IPU-fine-tuning-the-interlace-display-timing-for-CEA.patch This produces a working interlace format output from the IPU.

drm/imx: consolidate bus format variable names

2015-03-31T09:59:34Z

This patch consolidates the different interface_pix_fmt, pixel_fmt, pix_fmt, and pixfmt variables to a common name "bus_format" wherever they describe the pixel format on the bus between display controller and encoder hardware. At the same time, it renames imx_drm_panel_format to imx_drm_set_bus_format. Signed-off-by: Philipp Zabel Tested-by: Emil Renner Berthing

drm/imx: switch to use media bus formats

2015-03-31T09:59:34Z

imx-drm internally misused the V4L2_PIX_FMT constants, which are supposed to describe the pixel format of frame buffers in memory, to describe the pixel format on the bus between the display controller and the encoder hardware. Now that MEDIA_BUS_FMT constants are available to drm drivers, use those instead. Signed-off-by: Philipp Zabel Tested-by: Emil Renner Berthing
