drm/imx: fix build failure without CONFIG_DRM_FBDEV_EMULATION

2018-10-05T10:09:20+00:00

The variable is declared in an #ifdef section, but the user is now unconditional, which leads to a build failure: drivers/gpu/drm/imx/imx-drm-core.c: In function 'imx_drm_bind': drivers/gpu/drm/imx/imx-drm-core.c:264:6: error: 'legacyfb_depth' undeclared (first use in this function); did you mean 'lockdep_depth'? Remove the remaining #ifdef as well.

drm/imx: Use drm_fbdev_generic_setup()

2018-09-25T09:32:15+00:00

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. CONFIG_DRM_FBDEV_EMULATION wasn't honoured by the CMA helper, but it is by drm_fb_helper.

drm/imx: use suspend/resume helpers, add ipu-v3 V4L2 XRGB32/XBGR32 support - Convert imx_drm_suspend/resume to use the drm_mode_config_helper_suspend/ resume functions. - Add support for V4L2_PIX_FMT_XRGB32/XBGR32, corresponding to DRM_FORMAT_XRGB8888/BGRX8888, respectively.

drm/imx: Use __drm_atomic_helper_plane_reset instead of copying the logic

2018-08-06T10:47:03+00:00

A new helper function(__drm_atomic_helper_plane_reset) has been added for linking a plane with its state and resetting the core properties(alpha, rotation, etc.) to their default values. Use that instead of duplicating the logic.

drm/imx: Convert drm_atomic_helper_suspend/resume()

2018-08-01T07:39:00+00:00

convert drm_atomic_helper_suspend/resume() to use drm_mode_config_helper_suspend/resume(). with this conversion, the remaining member of struct imx_drm_device, state, will be no more useful and it could be removed forever.

drm/imx: cleanup and csi improvements - Remove the unused struct imx_drm_crtc and the unused pipes field from imx_drm_device and replace drm_dev_unref with drm_dev_put. - Extend CSI configuration to support RGB888 and BGR888 capture, as well as 16-bit RGB565 capture via a parallel bus. - Add CPMEM support for negative interlace offsets, which is necessary to support writing captured bottom-top interlaced fields to memory with interleaved lines.
