drm/sun4i: Fix an error handling path in 'sun4i_drv_bind()'

2018-03-12T09:42:09Z

Commit 070badfab767 ("drm/sun4i: call drm_vblank_init with correct number of crtcs") has moved some code without updating the error handling gotos accordingly. Branch to the correct label and remove a now unused lablel.

drm/sun4i: Add a driver for the display frontend

2018-01-22T14:15:38Z

The display frontend is an hardware block that can be used to implement some more advanced features like hardware scaling or colorspace conversions. It can also be used to implement the output format of the VPU. Let's create a minimal driver for it that will only enable the hardware scaling features.

drm/sun4i: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:42Z

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.

drm/sun4i: use sun4i_tcon_of_table to check if a device node is a TCON

2017-11-30T15:46:05Z

The sun4i DRM driver maintains a list of compatible strings it uses to check if a device node within the display component graph is a TCON. The TCON driver also has this list, used to bind the TCON driver to the device. These two lists are identical. Instead of maintaining two identical lists, export the list from the TCON driver for the DRM driver to use.

drm/sun4i: Add support for A20 display pipeline components

2017-10-17T17:49:17Z

The A20 display pipeline has 2 frontends, 2 backends, and 2 TCONs. This patch adds support (or a compatible string in the frontend's case) for these components. The TCONs support directly outputting to CPU/RGB/LVDS LCD panels, or it can output to HDMI via an on-chip HDMI controller, or CVBS/YPbPr/VGA signals via on-chip TV encoders. These additional encoders are not covered in this patch.
