drm/stm: Convert to struct drm_crtc_helper_funcs.get_scanout_position()

2020-02-13T12:09:22Z

The callback struct drm_driver.get_scanout_position() is deprecated in favor of struct drm_crtc_helper_funcs.get_scanout_position(). Convert stm over.

drm/stm: ltdc: add number of interrupts

2020-02-04T10:38:59Z

The number of interrupts depends on the ltdc version. Don't try to get interrupt which not exist, avoiding kernel warning messages.

drm: stm: implement get_scanout_position function

2018-09-27T13:04:26Z

Hardware allow to read the position in scanout buffer so we can use this information to make wait of vblank more accurate. Active area bounds (start, end, total height) have already been computed and written in ltdc registers, read them and get the current line position to compute vpos value.

drm/stm: ltdc: remove non-alpha color formats on layer 2 for older hw

2018-02-08T09:23:32Z

Hw older versions support non-alpha color formats derived from native alpha color formats only on the primary layer. For instance, RG16 native format without alpha works fine on 2nd layer but XR24 (derived color format from AR24) does not work on 2nd layer.

drm/stm: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:41Z

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly. Remove duplicate ldev assignment.
