From: Shawn Guo <shawn.guo at linaro.org>
The vblank is mostly CRTC specific and implemented as part of CRTC
driver. The first patch adds 3 vblank core<->driver hooks into struct
drm_crtc_funcs, and plug them into core by adding wrapper functions for
vblank handling code. We effectively make the .get_vblank_counter hook
optional by providing drm_vblank_no_hw_counter() as the default fallback
in the wrapper function.
Patch #2 and #3 unexport function drm_vblank_no_hw_counter() by cleaning
up its use, since it's already the default implememention for
.get_vblank_counter hook anyway.
The rest of the series is trying to do a massive conversion to the new
hooks for DRIVER_MODESET drivers. But it only handles low-hanging
fruit, and leaves out the ones that need a bit surgery, like gma500,
i915, msm etc. Most of conversion get done by simply moving code and
making functions static, but imx and rockchip are great examples showing
how driver code can be cleaned up with these new hooks.
The series is generated against branch drm-next.
Changes for v3:
- Let drm_vblank_no_hw_counter() be the last fallback for
.get_vblank_counter() hook.
- Improve the kernel-doc for .get_vblank_counter() hook.
- Convert more DRIVER_MODESET drivers to new hooks.
Changes for v2:
- Wrap around core vblank handling code to save
drm_crtc_enable[disable]_vblank() helpers
- Add .get_vblank_counter to struct drm_crtc_funcs
- Add some comments to link between two sets of hooks
- Add one hdlcd driver patch for example
