2014-11-26drm: imx: Move imx-drm driver out of stagingPhilipp Zabel1-296/+0
The imx-drm driver was put into staging mostly for the following reasons, all of which have been addressed or superseded: - convert the irq driver to use linear irq domains - work out the device tree bindings, this lead to the common of_graph bindings being used - factor out common helper functions, this mostly resulted in the component framework and drm of_graph helpers. Before adding new fixes, and certainly before adding new features, move it into its proper place below drivers/gpu/drm.

2014-06-19imx-drm: parallel-display: Fix DPMS default state.Denis Carikli1-0/+7
If connector->dpms is left untouched, it defaults to DRM_MODE_DPMS_ON (0). As a result, drm_helper_connector_dpms will exit when it will be asked to set the state to DRM_MODE_DPMS_ON, because it is already set. That issue prevented displays from turning on at boot.

2014-02-27imx-drm: parallel-display: Add drm_panel supportPhilipp Zabel1-0/+23
This patch allows to optionally attach the parallel-display to a panel supported by a drm_panel driver instead of supplying the modes via device tree. Before: parallel-display { compatible = "fsl,imx-parallel-display"; ... display-timings { native-timing = <&timing1>; timing1: etm0700g0dh6 { hactive = <800>; vactive = <480>; clock-frequency = <33260000>; hsync-len = <128>; hback-porch = <88>; hfront-porch = <40>; vsync-len = <2>; vback-porch = <33>; vfront-porch = <10>; hsync-active = <0>; vsync-active = <0>; ... }; }; ... }; After: parallel-display { compatible = "fsl,imx-parallel-display"; fsl,panel = <&panel>; ... }; panel: panel { compatible = "edt,etm0700g0dh6", "simple-panel"; }; Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-02-24imx-drm: initialise drm components directlyRussell King1-44/+17
Now that our bind function is only ever called during the main DRM driver ->load callback, we don't need to have the imx_drm_connector or imx_drm_encoder abstractions anymore. So let's get rid of it, and move the DRM connector and encoder setup into the connector support files.

2014-02-24imx-drm: simplify setup of panel formatRussell King1-2/+1
The encoder format passed into imx_drm_crtc_panel_format*() is the encoder format used for DRM in most cases; the HDMI encoder sets this to none, but this is incorrect, it should be TMDS. Since this is the case, we can pass the drm_encoder structure directly into this function and use the supplied fields there to configure the CRTC.

2014-01-13imx-drm: parallel-display: honor 'native-mode' property when selecting video mode from DTLothar Waßmann1-1/+2
This patch allows to select a specific video mode from a list of modes defined in DT by setting the 'native-mode' property appropriately. Since all current users of this driver have only one mode defined in their .dts files, the patch does not change the behaviour of this driver on the affected platforms.
