drm: zte: use devm_of_platform_populate()

2017-06-05T01:57:14+00:00

Use devm_of_platform_populate() to be sure that of_platform_depopulate is called when removing the driver.

drm: zte: add VGA driver support

2017-05-04T05:53:05+00:00

It adds VGA driver support, which needs to configure corresponding VOU interface in RGB_888 format, and thus the following changes are needed on zx_vou. - Rename the CSC block of Graphic Layer a bit to make it more specific, and add CSC of Channel to support RGB output. - Bypass Dither block for RGB output.

drm: zte: move CSC register definitions into a common header

2017-05-04T05:51:52+00:00

The CSC (Color Space Conversion) block in VOU is used by not only Graphic Layer (plane) but also channel (CRTC) module. Let's move its register definitions into a common header, so that CRTC driver can include it when needed.

drm: zte: do not enable clock auto-gating by default

2017-05-04T05:50:34+00:00

Some VOU modules do not work well with clock auto-gating. For example, VGA I2C bus will fail to read EDID data from monitor. Let's not enable this feature by default, and leave it to the possible future low-power optimization.

Pointer for Markus's image conversion work. We need this so we can merge all the pretty drm graphs for 4.12. Signed-off-by: Daniel Vetter

drm: Create DEFINE_DRM_GEM_CMA_FOPS and roll it out to drivers

2017-03-14T13:38:34+00:00

Less code ftw. This converts all drivers except the tinydrm helper module. That one needs more work, since it gets the THIS_MODULE reference from tinydrm.ko instead of the actual driver module like it should. Probably needs a similar trick like I used here with generating the entire struct with a macro.

drm: zte: use vblank hooks in struct drm_crtc_funcs

2017-02-09T08:13:20+00:00

The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead. The functions are moved around to save forward declaration.

drm: remove drm_vblank_no_hw_counter assignment from driver code

2017-02-07T20:43:55+00:00

Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now.
